Patients are not finding out until they go to pick up their prescription, which can result in an interruption of treatment – and, potentially a loss of hard-earned hair gain, said Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, who was the lead author of the survey, published online on Oct. 26 as a research letter in the Journal of Drugs in Dermatology.
Going off low-dose oral minoxidil may spark a telogen effluvium event, and that is very disappointing to patients, Dr. Friedman told this news organization.
“There needs to be some system that alerts us,” he said. “Even if it’s a minor shortage, just so we’re aware. We can then prepare patients,” he added, noting that it would be better for someone to be taking a lower-than-normal dose rather than no medication at all while they wait for a refill.
Minoxidil has long been approved in a topical formulation to treat androgenetic alopecia, but a low-dose oral form has gained currency in the wake of findings that it might more effectively treat hair loss, and is without side effects. A New York Times article in August 2022 touting low-dose oral minoxidil as a cheap and effective hair loss drug appeared to ignite interest in this option. In May, 2023, researchers reporting in JAMA Network Open demonstrated a significant uptick in prescriptions for oral minoxidil in the wake of the article’s publication.
Oral minoxidil is approved by the Food and Drug Administration only for hypertension, but dermatologists are prescribing it off-label at a lower dose for hair loss. Dr. Friedman said it’s not clear whether the shortages his team found are national in scope, or whether they are a result of increased demand, or other factors.
After several patients told him they were having trouble filling minoxidil prescriptions, and colleagues said they’d had patients with similar experiences, Dr. Friedman and his colleagues undertook the survey. In the first week of October 2023, they contacted 277 pharmacies by phone in Washington and surrounding Virginia and Maryland counties. The pharmacies were CVS, Giant, Walgreens, and Harris Teeter.
Of the 277 pharmacies they contacted, 40% (111) reported availability of 2.5-mg tablets for a 30-day supply, and just under 30% (82) reported having 10-mg tablets for a 30-day supply.
For treating hair loss, most patients are prescribed 2.5-mg pills, with starting doses ranging from 0.625 mg to 5 mg twice a day, Dr. Friedman said. The 10-mg dose is more frequently prescribed for hypertension.
Only 28% (19 of 67) of the Maryland pharmacies had 30-day supplies of 2.5-mg tablets on hand, and just 22% (15) of the Maryland pharmacies had 30-day supplies of 10-mg tablets. In Northern Virginia, 44% (63 of 143) of the pharmacies had 30-day supplies of the 2.5 mg tablets, as did just 43% (29 of 67) of the Washington pharmacies.
Dr. Friedman said he has started giving patients paper prescriptions they can use to shop around, rather than electronically sending a prescription to a particular pharmacy.
Neither the Food and Drug Administration nor the American Society of Health System Pharmacists lists oral minoxidil as a drug in shortage.
Michael Ganio, PharmD, senior director of pharmacy practice and quality for ASHP, said the organization received a report from wholesalers in mid-September showing spotty oral minoxidil availability, with the drug on backorder with some manufacturers. ASHP's shortages list is compiled from reports from physicians, manufacturers and wholesalers, he said.
Under what he calls "blue sky conditions," pharmacies using a just-in-time inventory model should be able to fill prescriptions within hours or days, which might explain why some pharmacies in the Washington, DC area survey did not have a 30-day supply on hand, he said. However, Dr. Ganio noted that the causes of drug shortages are complex and multi-factorial. For now, he said there have been no oral minoxidil shortage reports since mid-September.
But Dr. Friedman said some of his patients have waited weeks for a new supply – and that no one is aware of the problem until the last moment.
The lack of alerts or transparency “also erodes the physician-patient relationship because there’s this expectation of the patient that we should have known this,” said Dr. Friedman.
Dr. Friedman reports no relevant financial relationships.
