TLDR Some drugs used to treat inflammation may cause hair loss.
The study analyzed 282,590 spontaneous adverse drug reaction reports from the French Pharmacovigilance Database, identifying 1068 cases of alopecia, with 52 cases (4.9%) associated with TNF-α antagonist exposure, including drugs like infliximab, adalimumab, etanercept, and certolizumab. A significant association between TNF-α antagonists and alopecia was found, with a pooled reporting odds ratio of 3.0. The study confirmed a strong link between TNF-α antagonist exposure and the occurrence of alopecia, suggesting a class effect, despite TNF-α's known role in inhibiting hair growth and its implication in alopecia areata pathogenesis. The paradox is that while TNF-α antagonists are used to treat inflammatory diseases, they have been reported to induce alopecia, including alopecia areata. The document concludes that there is a confirmed association between TNF-α antagonist exposure and various types of alopecia.
