Medications That Can Cause Hirsutism

Hirsutism means excess coarse hair in areas influenced by androgens, such as the face, chest, or abdomen. Medicines may contribute by changing hormone signals or their effects on hair follicles. New or rapidly worsening growth can also have other causes, so medication exposure alone does not identify the diagnosis. A clinician may ask about menstrual changes, acne, voice change, and other symptoms. Learn more in [Hirsutism](/conditions/hirsutism/).

Write down every prescription, supplement, and performance or hormone-related product, with the date each began. Do not stop a prescribed medicine without advice. A clinician may consider an examination, medication adjustment, or hormone assessment. Hair-removal choices depend on hair colour, skin type, location, and whether growth is still active. Options include [Laser Hair Removal](/treatments/laser-and-energy/laser-hair-removal/) and [Electrolysis Hair Removal](/treatments/laser-and-energy/electrolysis-hair-removal/).

Book medical advice when excess hair is new, increasing quickly, or accompanied by irregular periods, deepening voice, scalp hair loss, severe acne, or increased muscle bulk. Seek prompt care for sudden, marked changes or symptoms suggesting a medicine reaction. Do not delay review while pursuing cosmetic removal if hormone-related symptoms are appearing.

Ask whether any current medicine could be contributing, whether testing is appropriate, and how long improvement might take after a safe change. Ask whether [Spironolactone Treatment](/treatments/medical-dermatology/spironolactone-therapy/) is suitable, including pregnancy and monitoring considerations.
