Hydrochlorothiazide, commonly referred to as HCTZ, is a diuretic medication that belongs to the thiazide group. It is often prescribed to treat high blood pressure and edema. While hydrochlorothiazide is generally well-tolerated, it can cause certain side effects, including hair loss.
The occurrence of hair loss as a side effect of hydrochlorothiazide is relatively uncommon, affecting a small percentage of patients. In most cases, hair loss is mild and resolves once the medication is discontinued. In some cases, however, hair loss can be more severe and may require treatment.
