In recent years, direct-to-consumer (DTC) teledermatology platforms have gained popularity as telehealth business models, allowing patients to directly initiate visits with physicians and purchase medications from single platforms. A shortage of dermatologists, improved technology, drug patent expirations, and rising health care costs accelerated the growth of DTC dermatology.¹ During the COVID-19 pandemic, teledermatology adoption surged due to the need to provide care while social distancing and minimizing viral exposure. These needs prompted additional federal funding and loosened regulatory provisions.² As the userbase of these companies has grown, so have their valuations.³ Although the DTC model has attracted the attention of patients and investors, its rise provokes many questions about patients acting as consumers in health care. Indeed, DTC telemedicine offers greater autonomy and convenience for patients, but it may impact the quality of care and the nature of physician-patient relationships, perhaps making them more transactional.

Evolution of DTC in Health Care

The DTC model emphasizes individual choice and accessible health care. Although the definition has evolved, the core idea is not new.⁴ Over decades, pharmaceutical companies have spent billions of dollars on DTC advertising, circumventing physicians by directly reaching patients with campaigns on prescription drugs and laboratory tests and shaping public definitions of diseases.⁵

The DTC model of care is fundamentally different from traditional care models in that it changes the roles of the patient and physician. Whereas early telehealth models required a health care provider to initiate teleconsultations with specialists, DTC telemedicine bypasses this step (eg, the patient can consult a dermatologist without needing a primary care provider’s input first). This care can then be provided by dermatologists with whom patients may or may not have pre-established relationships.^4,6

Dermatology was an early adopter of DTC telemedicine. The shortage of dermatologists in the United States created demand for increasing accessibility to dermatologic care. Additionally, the visual nature of diagnosing dermatologic disease was ideal for platforms supporting image sharing.⁷ Early DTC providers were primarily individual companies offering teledermatology. However, many dermatologists can now offer DTC capabilities via companies such as Amwell and Teladoc Health.⁸

Over the last 2 decades, start-ups such as Warby Parker (eyeglasses) and Casper (mattresses) defined the DTC industry using borrowed supply chains, cohesive branding, heavy social media marketing, and web-only retail. Scalability, lack of competition, and abundant venture capital created competition across numerous markets.⁹ Health care capitalized on this DTC model, creating a $700 billion market for products ranging from hearing aids to over-the-counter medications.¹⁰

Borrowing from this DTC playbook, platforms were created to offer delivery of generic prescription drugs to patients’ doorsteps. However, unlike with other products bought online, a consumer cannot simply add prescription drugs to their shopping cart and check out. In all models of American medical practice, physicians still serve as gatekeepers, providing a safeguard for patients to ensure appropriate prescription and avoid negative consequences of unnecessary drug use. This new model effectively streamlines diagnosis, prescription, and drug delivery without the patient ever having to leave home. Combining the prescribing and selling of medications (2 tasks that traditionally have been separated) potentially creates financial conflicts of interest (COIs). Additionally, high utilization of health care, including more prescriptions and visits, does not necessarily equal high quality of care. The companies stand to benefit from extra care regardless of need, and thus these models must be scrutinized for any incentives driving unnecessary care and prescriptions.

Ultimately, DTC has evolved to encompass multiple definitions in health care (Table 1). Although all models provide health care, each offers a different modality of delivery. The primary service may be the sale of prescription drugs or simply telemedicine visits. This review primarily discusses DTC pharmaceutical telemedicine platforms that sell private-label drugs and also offer telemedicine services to streamline care. However, the history, risks, and benefits discussed may apply to all models.

The DTC Landscape

Most DTC companies employ variations on a model with the same 3 main components: a triage questionnaire, telehealth services, and prescription/drug delivery (Figure). The triage questionnaire elicits a history of the patient’s presentation and medical history. Some companies may use artificial intelligence (AI) algorithms to tailor questions to patient needs. There are 2 modalities for patient-provider communication: synchronous and asynchronous. Synchronous communication entails real-time patient-physician conversations via audio only or video call. Asynchronous (or store-and-forward) communication refers to consultations provided via messaging or text-based modality, where a provider may respond to a patient within 24 hours.⁶ Direct-to-consumer platforms primarily use asynchronous visits (Table 2). However, some also use synchronous modalities if the provider deems it necessary or if state laws require it.

Once a provider has consulted with the patient, they can prescribe medication as needed. In certain cases, with adequate history, a prescription may be issued without a full physician visit. Furthermore, DTC companies require purchase of their custom-branded generic drugs. Prescriptions are fulfilled by the company’s pharmacy network and directly shipped to patients; few will allow patients to transfer a prescription to a pharmacy of their choice. Some platforms also sell supplements and over-the-counter medications.

Payment models vary among these companies, and most do not accept insurance (Table 2). Select models may provide free consultations and only require payment for pharmaceuticals. Others charge for consultations but reallocate payment to the cost of medication if prescribed. Another model involves flat rates for consultations and additional charges for drugs but unlimited messaging with providers for the duration of the prescription. Moreover, patients can subscribe to monthly deliveries of their medications.

Foundation of DTC

Technological advances have enabled patients to receive remote treatment from a single platform offering video calls, AI, electronic medical record interoperability, and integration of drug supply chains. Even in its simplest form, AI is increasingly used, as it allows for programs and chatbots to screen and triage patients.¹¹ Technology also has improved at targeted mass marketing through social media platforms and search engines (eg, companies can use age, interests, location, and other parameters to target individuals likely needing acne treatment).

Drug patent expirations are a key catalyst for the rise of DTC companies, creating an attractive business model with generic drugs as the core product. Since 2008, patents for medications treating chronic conditions, such as erectile dysfunction, have expired. These patent expirations are responsible for $198 billion in projected prescription sales between 2019 and 2024.¹ Thus, it follows that DTC companies have seized this opportunity to act as middlemen, taking advantage of these generic medications’ lower costs to create platforms focused on personalization and accessibility.

Rising deductibles have led patients to consider cheaper out-of-pocket alternatives that are not covered by insurance.¹ For example, insurers typically do not cover finasteride treatment for conditions deemed cosmetic, such as androgenetic alopecia.¹² The low cost of generic drugs creates an attractive business model for patients and investors. According to GoodRx, the average retail price for a 30-day supply of brand-name finasteride (Propecia [Merck]) is $135.92, whereas generic finasteride is $75.24.¹³ Direct-to-consumer pharmaceutical companies offer a 30-day supply of generic finasteride ranging from $8.33 to $30.¹⁴ The average wholesale cost for retailers is an estimated $2.31 for 30 days.¹⁵ Although profit margins on generic medications may be lower, more affordable drugs increase the size of the total market. These prescriptions are available as subscription plans, resulting in recurring revenue.

Lax US pharmaceutical marketing regulations allow direct advertising to the general public.¹⁶ In 1997, the US Food and Drug Administration allowed DTC advertisements to replace summaries of serious and common adverse effects with short statements covering important risks or referrals to other sources for complete information. In 2015, the US Food and Drug Administration guidelines preventing encouragement of self-diagnosis and self-treatment were withdrawn.⁵ These changes enable DTC companies to launch large advertising campaigns and to accelerate customer acquisition, as the industry often describes it, with ease.

Rapid Growth and Implications

Increasing generic drug availability and improving telemedicine capabilities have the potential to reduce costs and barriers but also have the potential for financial gain. Venture capital funds have recognized this opportunity, reflected by millions of dollars of investments, and accelerated the growth of DTC health care start-ups. For example, Ro has raised $376 million from venture capital, valuing the company at $1.5 billion.³

Direct-to-consumer companies require a heavy focus on marketing campaigns for customer acquisition. Their aesthetically pleasing websites and aggressive campaigns target specific audiences based on demographics, digital use habits, and purchasing behavior.⁴ Some campaigns celebrate the ease of obtaining prescriptions.¹⁷ Companies have been effective in recruiting so-called millennial and Generation Z patients, known to search the internet for remedies prior to seeking physician consultations.¹⁸ Recognizing these needs, some platforms offer guides on diseases they treat, creating effective customer-acquisition funnels. Recruitment of these technology-friendly patients has proven effective, especially given the largely positive media coverage of DTC platforms––potentially serving as a surrogate for medical credibility for patients.¹⁸

Some DTC companies also market physically; skin care ads may be strategically placed in social media feeds, or even found near mirrors in public bathrooms.¹⁹ Marketing campaigns also involve disease awareness; such efforts serve to increase diagnoses and prescribed treatments while destigmatizing diseases. Although DTC companies argue this strategy empowers patients, these marketing habits have the potential to take advantage of uninformed patients. Campaigns could potentially medicalize normal experiences and expand disease definitions resulting in overdiagnosis, overtreatment, and wasted resources.⁵ For example, off-label propranolol use has been advertised to attract patients who might have “nerves that come creeping before an important presentation.”¹⁷ Disease awareness campaigns also may lead people to falsely believe unproven drug benefits.⁵ According to studies, DTC pharmaceutical advertisements are low in informational quality and result in increased patient visits and prescriptions despite cost-effective alternatives.^5,20-22

Fragmentation of the health care system is another possible complication of DTC teledermatology. These companies operate as for-profit organizations separated from the rest of the health care system, raising concerns about care coordination.⁸ Vital health data may not be conveyed as patients move among different providers and pharmacies. One study found DTC teledermatology rarely offered to provide medical records or facilitate a referral to a local physician.²³ Such a lack of communication is concerning, as medication errors are the leading cause of avoidable harm in health care.²⁴

Direct-to-consumer care models also seemingly redefine the physician-patient relationship by turning patients into consumers. Patient interactions may seem transactional and streamlined toward sales. For these platforms, a visit often is set up as an evaluation of a patient’s suitability for a prescription, not necessarily for the best treatment modality for the problem. These companies primarily make money through the sale of prescription drugs, creating a potential COI that may undermine the patient-physician relationship. Although some companies have made it clear that medical care and pharmaceutical sales are provided by legally separate business entities and that they do not pay physicians on commission, a conflict may still exist given the financial importance of physicians prescribing medication to the success of the business.¹⁶

Even as DTC models advertise upon expanded access and choice, the companies largely prohibit patients from choosing their own pharmacy. Instead, they encourage patients to fill prescriptions with the company’s pharmacy network by claiming lower costs compared with competitors. One DTC company, Hims, is launching a prescription-fulfillment center to further consolidate their business.^17,19,25 The inherent COI of issuing and fulfilling prescriptions raises concerns of patient harm.²⁶ For example, when Dermatology.com launched as a DTC prescription skin medication shop backed by Bausch Health Companies Inc, its model included telemedicine consultation. Although consultations were provided by RxDefine, a third party, only Dermatology.com drugs were prescribed. Given the poor quality of care and obvious financial COI, an uproar in the dermatology community and advocacy by the American Academy of Dermatology led to the shutdown of Dermatology.com’s online prescription services.²⁶

The quality of care among DTC telemedicine platforms has been equivocal. Some studies have reported equivalent care in person and online, while others have reported poor adherence to guidelines, overuse of antibiotics, and misdiagnosis.^8,23 A vital portion of the DTC experience is the history questionnaire, which is geared to diagnosis and risk assessment.²⁵ Resneck et al²³ found diagnostic quality to be adequate for simple dermatologic clinical scenarios but poor for scenarios requiring more than basic histories. Although Ro has reported leveraging data from millions of interactions to ask the right questions and streamline visits, it is still unclear whether history questionnaires are adequate.^17,27 Additionally, consultations may lack sufficient counseling on adverse effects, risks, or pregnancy warnings, as well as discussions on alternative treatments and preventative care.^17,23 Finally, patients often are limited in their choice of dermatologist; the lack of a fully developed relationship increases concerns of follow-up and monitoring practices. Although some DTC platforms offer unlimited interactions with physicians for the duration of a prescription, it is unknown how often these services are utilized or how adequate the quality of these interactions is. This potential for lax follow-up is especially concerning for prescriptions that autorenew on a monthly basis and could result in unnecessary overtreatment.

Postpandemic and Future Outlook

The COVID-19 pandemic dramatically impacted the use of telemedicine. To minimize COVID-19 transmission, the Centers for Medicare & Medicaid Services and private payers expanded telehealth coverage and eliminated reimbursement and licensing barriers.²⁸ A decade’s worth of regulatory changes and consumer adoption was accelerated to weeks, resulting in telemedicine companies reaching record-high visit numbers.²⁹ McKinsey & Company estimated that telehealth visit numbers surged 50- to 175-fold compared with pre–COVID-19 numbers. Additionally, 76% of patients were interested in future telehealth use, and 64% of providers were more comfortable using telehealth than before the pandemic.³⁰ For their part, US dermatologists reported an increase in telemedicine use from 14.1% to 96.9% since COVID-19.³¹

Exactly how much DTC pharmaceutical telemedicine companies are growing is unclear, but private investments may be an indication. A record $14.7 billion was invested in the digital health sector in the first half of 2021; the majority went to telehealth companies.³⁰ Ro, which reported $230 million in revenue in 2020 and has served 6 million visits, raised $200 milllion in July 2020 and $500 million in March 2021.³² Although post–COVID-19 health care will certainly involve increased telemedicine, the extent remains unclear, as telehealth vendors saw decreased usage upon reopening of state economies. Ultimately, the postpandemic regulatory landscape is hard to predict.³⁰

Although COVID-19 appears to have caused rapid growth for DTC platforms, it also may have spurred competition. Telemedicine providers have given independent dermatologists and health care systems the infrastructure to implement custom DTC services.³³ Although systems do not directly sell prescription drugs, the target market is essentially the same: patients looking for instant virtual dermatologic care. Therefore, sustained telemedicine services offered by traditional practices and systems may prove detrimental to DTC companies. However, unlike most telemedicine services, DTC models are less affected by certain changes in regulation since they do not rely on insurance. If regulations are tightened and reimbursements for telehealth are not attractive for dermatologists, teledermatology services may see an overall decrease. If so, patients who appreciate teledermatology may shift to using DTC platforms, even if their insurance does not cover them. Still, a nationwide survey found 56% of respondents felt an established relationship with a physician prior to a telemedicine visit is important, which may create a barrier for DTC adoption.³⁴

Conclusion

Direct-to-consumer teledermatology represents a growing for-profit model of health care that provides patients with seemingly affordable and convenient care. However, there is potential for overtreatment, misdiagnosis, and fragmentation of health care. It will be important to monitor and evaluate the quality of care that DTC teledermatology offers and advocate for appropriate regulations and oversight. Eventually, more patients will have medications prescribed and dermatologic care administered through DTC companies. Dermatologists will benefit from this knowledge of DTC models to properly counsel patients on the risks and benefits of their use.

Asynchronous (or store-and-forward) communication refers to consultations provided via messaging or text-based modality, where a provider may respond to a patient within 24 hours.⁶ Direct-to-consumer platforms primarily use asynchronous visits (Table 2). However, some also use synchronous modalities if the provider deems it necessary or if state laws require it.

Once a provider has consulted with the patient, they can prescribe medication as needed. In certain cases, with adequate history, a prescription may be issued without a full physician visit. Furthermore, DTC companies require purchase of their custom-branded generic drugs. Prescriptions are fulfilled by the company’s pharmacy network and directly shipped to patients; few will allow patients to transfer a prescription to a pharmacy of their choice. Some platforms also sell supplements and over-the-counter medications.

Payment models vary among these companies, and most do not accept insurance (Table 2). Select models may provide free consultations and only require payment for pharmaceuticals. Others charge for consultations but reallocate payment to the cost of medication if prescribed. Another model involves flat rates for consultations and additional charges for drugs but unlimited messaging with providers for the duration of the prescription. Moreover, patients can subscribe to monthly deliveries of their medications.

Foundation of DTC

Technological advances have enabled patients to receive remote treatment from a single platform offering video calls, AI, electronic medical record interoperability, and integration of drug supply chains. Even in its simplest form, AI is increasingly used, as it allows for programs and chatbots to screen and triage patients.¹¹ Technology also has improved at targeted mass marketing through social media platforms and search engines (eg, companies can use age, interests, location, and other parameters to target individuals likely needing acne treatment).

Drug patent expirations are a key catalyst for the rise of DTC companies, creating an attractive business model with generic drugs as the core product. Since 2008, patents for medications treating chronic conditions, such as erectile dysfunction, have expired. These patent expirations are responsible for $198 billion in projected prescription sales between 2019 and 2024.¹ Thus, it follows that DTC companies have seized this opportunity to act as middlemen, taking advantage of these generic medications’ lower costs to create platforms focused on personalization and accessibility.

Rising deductibles have led patients to consider cheaper out-of-pocket alternatives that are not covered by insurance.¹ For example, insurers typically do not cover finasteride treatment for conditions deemed cosmetic, such as androgenetic alopecia.¹² The low cost of generic drugs creates an attractive business model for patients and investors. According to GoodRx, the average retail price for a 30-day supply of brand-name finasteride (Propecia [Merck]) is $135.92, whereas generic finasteride is $75.24.¹³ Direct-to-consumer pharmaceutical companies offer a 30-day supply of generic finasteride ranging from $8.33 to $30.¹⁴ The average wholesale cost for retailers is an estimated $2.31 for 30 days.¹⁵ Although profit margins on generic medications may be lower, more affordable drugs increase the size of the total market. These prescriptions are available as subscription plans, resulting in recurring revenue.

Lax US pharmaceutical marketing regulations allow direct advertising to the general public.¹⁶ In 1997, the US Food and Drug Administration allowed DTC advertisements to replace summaries of serious and common adverse effects with short statements covering important risks or referrals to other sources for complete information. In 2015, the US Food and Drug Administration guidelines preventing encouragement of self-diagnosis and self-treatment were withdrawn.⁵ These changes enable DTC companies to launch large advertising campaigns and to accelerate customer acquisition, as the industry often describes it, with ease.

Rapid Growth and Implications

Increasing generic drug availability and improving telemedicine capabilities have the potential to reduce costs and barriers but also have the potential for financial gain. Venture capital funds have recognized this opportunity, reflected by millions of dollars of investments, and accelerated the growth of DTC health care start-ups. For example, Ro has raised $376 million from venture capital, valuing the company at $1.5 billion.³

Direct-to-consumer companies require a heavy focus on marketing campaigns for customer acquisition. Their aesthetically pleasing websites and aggressive campaigns target specific audiences based on demographics, digital use habits, and purchasing behavior.⁴ Some campaigns celebrate the ease of obtaining prescriptions.¹⁷ Companies have been effective in recruiting so-called millennial and Generation Z patients, known to search the internet for remedies prior to seeking physician consultations.¹⁸ Recognizing these needs, some platforms offer guides on diseases they treat, creating effective customer-acquisition funnels. Recruitment of these technology-friendly patients has proven effective, especially given the largely positive media coverage of DTC platforms––potentially serving as a surrogate for medical credibility for patients.¹⁸

Some DTC companies also market physically; skin care ads may be strategically placed in social media feeds, or even found near mirrors in public bathrooms.¹⁹ Marketing campaigns also involve disease awareness; such efforts serve to increase diagnoses and prescribed treatments while destigmatizing diseases. Although DTC companies argue this strategy empowers patients, these marketing habits have the potential to take advantage of uninformed patients. Campaigns could potentially medicalize normal experiences and expand disease definitions resulting in overdiagnosis, overtreatment, and wasted resources.⁵ For example, off-label propranolol use has been advertised to attract patients who might have “nerves that come creeping before an important presentation.”¹⁷ Disease awareness campaigns also may lead people to falsely believe unproven drug benefits.⁵ According to studies, DTC pharmaceutical advertisements are low in informational quality and result in increased patient visits and prescriptions despite cost-effective alternatives.^5,20-22

Fragmentation of the health care system is another possible complication of DTC teledermatology. These companies operate as for-profit organizations separated from the rest of the health care system, raising concerns about care coordination.⁸ Vital health data may not be conveyed as patients move among different providers and pharmacies. One study found DTC teledermatology rarely offered to provide medical records or facilitate a referral to a local physician.²³ Such a lack of communication is concerning, as medication errors are the leading cause of avoidable harm in health care.²⁴

Direct-to-consumer care models also seemingly redefine the physician-patient relationship by turning patients into consumers. Patient interactions may seem transactional and streamlined toward sales. For these platforms, a visit often is set up as an evaluation of a patient’s suitability for a prescription, not necessarily for the best treatment modality for the problem. These companies primarily make money through the sale of prescription drugs, creating a potential COI that may undermine the patient-physician relationship. Although some companies have made it clear that medical care and pharmaceutical sales are provided by legally separate business entities and that they do not pay physicians on commission, a conflict may still exist given the financial importance of physicians prescribing medication to the success of the business.¹⁶

Even as DTC models advertise upon expanded access and choice, the companies largely prohibit patients from choosing their own pharmacy. Instead, they encourage patients to fill prescriptions with the company’s pharmacy network by claiming lower costs compared with competitors. One DTC company, Hims, is launching a prescription-fulfillment center to further consolidate their business.^17,19,25 The inherent COI of issuing and fulfilling prescriptions raises concerns of patient harm.²⁶ For example, when Dermatology.com launched as a DTC prescription skin medication shop backed by Bausch Health Companies Inc, its model included telemedicine consultation. Although consultations were provided by RxDefine, a third party, only Dermatology.com drugs were prescribed. Given the poor quality of care and obvious financial COI, an uproar in the dermatology community and advocacy by the American Academy of Dermatology led to the shutdown of Dermatology.com’s online prescription services.²⁶

The quality of care among DTC telemedicine platforms has been equivocal. Some studies have reported equivalent care in person and online, while others have reported poor adherence to guidelines, overuse of antibiotics, and misdiagnosis.^8,23 A vital portion of the DTC experience is the history questionnaire, which is geared to diagnosis and risk assessment.²⁵ Resneck et al²³ found diagnostic quality to be adequate for simple dermatologic clinical scenarios but poor for scenarios requiring more than basic histories. Although Ro has reported leveraging data from millions of interactions to ask the right questions and streamline visits, it is still unclear whether history questionnaires are adequate.^17,27 Additionally, consultations may lack sufficient counseling on adverse effects, risks, or pregnancy warnings, as well as discussions on alternative treatments and preventative care.^17,23 Finally, patients often are limited in their choice of dermatologist; the lack of a fully developed relationship increases concerns of follow-up and monitoring practices. Although some DTC platforms offer unlimited interactions with physicians for the duration of a prescription, it is unknown how often these services are utilized or how adequate the quality of these interactions is. This potential for lax follow-up is especially concerning for prescriptions that autorenew on a monthly basis and could result in unnecessary overtreatment.

Postpandemic and Future Outlook

The COVID-19 pandemic dramatically impacted the use of telemedicine. To minimize COVID-19 transmission, the Centers for Medicare & Medicaid Services and private payers expanded telehealth coverage and eliminated reimbursement and licensing barriers.²⁸ A decade’s worth of regulatory changes and consumer adoption was accelerated to weeks, resulting in telemedicine companies reaching record-high visit numbers.²⁹ McKinsey & Company estimated that telehealth visit numbers surged 50- to 175-fold compared with pre–COVID-19 numbers. Additionally, 76% of patients were interested in future telehealth use, and 64% of providers were more comfortable using telehealth than before the pandemic.³⁰ For their part, US dermatologists reported an increase in telemedicine use from 14.1% to 96.9% since COVID-19.³¹

Exactly how much DTC pharmaceutical telemedicine companies are growing is unclear, but private investments may be an indication. A record $14.7 billion was invested in the digital health sector in the first half of 2021; the majority went to telehealth companies.³⁰ Ro, which reported $230 million in revenue in 2020 and has served 6 million visits, raised $200 milllion in July 2020 and $500 million in March 2021.³² Although post–COVID-19 health care will certainly involve increased telemedicine, the extent remains unclear, as telehealth vendors saw decreased usage upon reopening of state economies. Ultimately, the postpandemic regulatory landscape is hard to predict.³⁰

Although COVID-19 appears to have caused rapid growth for DTC platforms, it also may have spurred competition. Telemedicine providers have given independent dermatologists and health care systems the infrastructure to implement custom DTC services.³³ Although systems do not directly sell prescription drugs, the target market is essentially the same: patients looking for instant virtual dermatologic care. Therefore, sustained telemedicine services offered by traditional practices and systems may prove detrimental to DTC companies. However, unlike most telemedicine services, DTC models are less affected by certain changes in regulation since they do not rely on insurance. If regulations are tightened and reimbursements for telehealth are not attractive for dermatologists, teledermatology services may see an overall decrease. If so, patients who appreciate teledermatology may shift to using DTC platforms, even if their insurance does not cover them. Still, a nationwide survey found 56% of respondents felt an established relationship with a physician prior to a telemedicine visit is important, which may create a barrier for DTC adoption.³⁴

Conclusion

Direct-to-consumer teledermatology represents a growing for-profit model of health care that provides patients with seemingly affordable and convenient care. However, there is potential for overtreatment, misdiagnosis, and fragmentation of health care. It will be important to monitor and evaluate the quality of care that DTC teledermatology offers and advocate for appropriate regulations and oversight. Eventually, more patients will have medications prescribed and dermatologic care administered through DTC companies. Dermatologists will benefit from this knowledge of DTC models to properly counsel patients on the risks and benefits of their use.

Rosacea fulminans (RF) is a rare facial dermatosis characterized by its fulminating course. ¹ It presents with superficial and deep-seated papules, pustules, and nodules combined with an intense reddish or cyanotic erythema localized to the face. Furthermore, there is an absence of comedones and involvement of the chest or back. ² Rosacea fulminans primarily affects women and often is, but not always, proceeded by seborrhea, chronic acne vulgaris, or rosacea. Although the etiology of RF remains unknown, immunologic, hormonal, and vascular factors have been implicated. ³ We report a case of RF in a pregnant patient with a history of mild acne as a teenager that was long ago resolved.

Case Report

A 32-year-old pregnant woman (10 weeks’ gestation) presented with a rapidly progressing inflammatory disorder of the face of 1 month’s duration. The lesions developed 3 weeks after beginning progesterone therapy (200 mg vaginal suppository) for infertility due to polycystic ovary syndrome. Despite discontinuing progesterone for the last month, the patient’s lesions had dramatically worsened (Figure 1). Empiric cephalosporin treatment prescribed by her primary care physician yielded no improvement. Physical examination at the current presentation revealed erythematous nodules and pustules all over the face, coalescing into large thick plaques on the patient’s right cheek and chin. Submental nodes were palpable and tender. Based on the initial clinical findings, acne conglobata secondary to progesterone therapy was considered. The patient was given intralesional triamcinolone (2.5 mg/cc) injections to all larger nodules and several blue light treatments.

The injected areas had improved 5 days after the initial visit; however, the chin and right paranasal cheek developed even more nodules and papules coalescing into large plaques. After consulting the patient’s obstetrician, prednisone (20 mg once daily) was initiated. Three weeks later, the patient’s nodular lesions had improved, but there was a showering of more than 100 pustules and increased general erythema of the entire face (Figure 2). Crotamiton cream 10% (every day before noon), ivermectin cream 1% (every night at bedtime), and sodium sulfacetamide cleanser 10% once daily were added to the treatment plan.

The patient delivered a healthy girl (birth weight, 1.985 kg) prematurely at 34 weeks’ gestation. At 2 months postpartum, the patient’s existing lesions continued to spontaneously improve; however, she still had numerous nodules and papules and continued to develop new lesions and form additional scars. Isotretinoin was instituted at 3 months postpartum upon cessation of nursing. Three months later (40 mg/d isotretinoin), the patient was nearly clear. At 8 months postpartum, isotretinoin was discontinued after a course of 150 mg/kg.

Comment

Rosacea fulminans initially was called pyoderma faciale but was later regarded as a severe form of rosacea and was renamed rosacea fulminans.² According to a PubMed search of articles indexed for MEDLINE using the terms pregnancy and rosacea fulminans or pyoderma faciale, we identified 12 publications reporting 20 cases of RF associated with pregnancy (Table). Although there is no substantial evidence regarding the exact mechanism, these cases indicate that pregnancy can be an exacerbating or causative factor in the pathogenesis of RF.

In addition to pregnancy, RF has been associated with inflammatory bowel disease, thyroid and liver disease, erythema nodosum, and severe emotional trauma. However, no organism has been consistently isolated, and no evidence of family history has been reported.¹ Histopathologic findings are dependent on the stage of disease. Massive infiltrates of neutrophils may be observed in early stages. In older lesions, infiltrates take the form of epithelioid cell granulomas.²

Treatment of RF during pregnancy is challenging. Early and aggressive treatment with retinoids, tetracycline antibiotics, antiandrogenic contraceptives, and dapsone is recommended in patients who are not pregnant; these therapies are all contraindicated in pregnancy. Topical steroids can be safely used; however, systemic steroids usually are required to control RF. The use of systemic steroids can only be justified if the risks for intrauterine growth retardation, maternal diabetes mellitus, and hypertension outweigh the benefits of treating this severe disfiguring skin condition.¹⁰ A study by Bakar et al¹³ indicated that azithromycin is an effective and safe alternative in the treatment of RF. It has a superior pharmacokinetic profile compared to other macrolides and does not pose increased risks for congenital malformation or miscarriage. Because of the concomitant use of both azithromycin and prednisone, it is not possible to determine which had the larger role in the patient’s improvement.

Isotretinoin therapy in our patient led to substantial improvement of RF. Time will tell if the response will be durable. Also unknown is the risk for recurrence with subsequent pregnancies, which has not been reported in the literature. Although it is difficult to confidently say that pregnancy was the inciting factor in this patient’s RF, this case certainly provides more evidence for a link between pregnancy and RF.
