The weekly rate of first-time low-dose oral minoxidil (LDOM) prescriptions per 10,000 outpatient encounters was “significantly higher 8 weeks after vs. 8 weeks before article publication,” at 0.9 prescriptions, compared with 0.5 per 10,000, wrote the authors of the research letter, published in JAMA Network Open. There was no similar bump for first-time finasteride or hypertension prescriptions, wrote the authors, from Harvard Medical School and Massachusetts General Hospital, Boston, and Truveta, a company that provides EHR data from U.S. health care systems.
The New York Times article noted that LDOM was relatively unknown to patients and doctors – and not approved by the Food and Drug Administration for treating hair loss – but that it was inexpensive, safe, and very effective for many individuals. “The article did not report new research findings or large-scale randomized evidence,” wrote the authors of the JAMA study.
Dr. Rodney Sinclair
Rodney Sinclair, MD, professor of dermatology at the University of Melbourne, who conducted the original research on LDOM and hair loss and was quoted in the Times story, told this news organization that “the sharp uplift after the New York Times article was on the back of a gradual increase.” He added that “the momentum for minoxidil prescriptions is increasing,” so much so that it has led to a global shortage of LDOM. The drug appears to still be widely available in the United States, however. It is not on the ASHP shortages list.
“There has been growing momentum for minoxidil use since I first presented our data about 6 years ago,” Dr. Sinclair said. He noted that 2022 International Society of Hair Restoration Surgery survey data found that 26% of treating physicians always or often prescribed off-label oral minoxidil, up from 10% in 2019 and 0% in 2017, while another 20% said they prescribed it sometimes.
The authors of the new study looked at prescriptions for patients at eight health care systems before and after the Times article was published in August 2022. They calculated the rate of first-time oral minoxidil prescriptions for 2.5 mg and 5 mg tablets, excluding 10 mg tablets, which are prescribed for hypertension.
Among those receiving first-time prescriptions, 2,846 received them in the 7 months before the article and 3,695 in the 5 months after publication. Men (43.6% after vs. 37.7% before publication) and White individuals (68.6% after vs. 60.8% before publication) accounted for a higher proportion of prescriptions after the article was published. There was a 2.4-fold increase in first-time prescriptions among men, and a 1.7-fold increase among females, while people with comorbidities accounted for a smaller proportion after the publication.
“Socioeconomic factors, such as access to health care and education and income levels, may be associated with individuals seeking low-dose oral minoxidil after article publication,” wrote the authors.
Dr. Adam Friedman
In an interview, Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, said that he was not surprised to see an uptick in prescriptions after the Times article.
He and his colleagues were curious as to whether the article might have prompted newfound interest in LDOM. They experienced an uptick at George Washington, which Dr. Friedman thought could have been because he was quoted in the Times story. He and colleagues conducted a national survey of dermatologists asking if more patients had called, emailed, or come in to the office asking about LDOM after the article’s publication. “Over 85% said yes,” Dr. Friedman said in the interview. He and his coauthors also found a huge increase in Google searches for terms such as hair loss, alopecia, and minoxidil in the weeks after the article, he said.
The results are expected to published soon in the Journal of Drugs in Dermatology.
“I think a lot of people know about [LDOM] and it’s certainly has gained a lot more attention and acceptance in recent years,” said Dr. Friedman, but he added that “there’s no question” that the Times article increased interest.
That is not necessarily a bad thing, he said. “With one article, education on a common disease was disseminated worldwide in a way that no one doctor can do,” he said. The article was truthful, evidence-based, and included expert dermatologists, he noted.
“It probably got people who never thought twice about their hair thinning to actually think that there’s hope,” he said, adding that it also likely prompted them to seek care, and, more importantly, “to seek care from the person who should be taking care of this, which is the dermatologist.”
However, the article might also inspire some people to think LDOM can help when it can’t, or they might insist on a prescription when another medication is more appropriate, said Dr. Friedman.
Both he and Dr. Sinclair expect demand for LDOM to continue increasing.
“Word of mouth will drive the next wave of prescriptions,” said Dr. Sinclair. “We are continuing to do work to improve safety, to understand its mechanism of action, and identify ways to improve equity of access to treatment for men and women who are concerned about their hair loss and motivated to treat it,” he said.
