Mark's doctor said she believes the symptoms that he reported to her were caused by the hair loss drug. HIMSS declined to comment on Mark's care. Many of Mark's symptoms weren't identified as potential side effects during Finasteride's clinical trials and aren't listed on the drug's label.

My colleague Rolf spoke to an endocrinologist who said the clinical trials had flaws that might have underestimated the incidence and severity of side effects, and that they didn't follow its subjects long enough.

Organon said it didn't run the trials and stood by the drug's safety and efficacy. Regulators have revisited finasteride side effects in the past. In 2011 and 2012, the FDA revised the drug's label to highlight sexual side effects. In 2022, the agency updated the drug's label to include the risks of, quote, suicidal ideation and behavior.

The side effects that HIMSS and other telehealth companies list on their websites are based on what's on the drug's label. Most men tolerate finasteride well. The drug's label currently says 3.8% of patients experienced one or more sexual side effects during the clinical trial. The risk of experiencing one of the main sexual side effects was under 2%.
