Mostly self-limiting hair loss caused by taking certain drugs, which occurs 2-6 months after the triggering event.
EtiopathogenesisThis section has been translated automatically.
Medications that can cause hair loss:
- Cytostatics/immunosuppressants: e.g. cyclophosphamide, methotrexate, colchicine, azathioprine, prednisone. General alopecia incidence for chemotherapeutics is about 65%.
- Targeted tumor therapeutics (especially inihbitoren of the Hedgehog, VEGF, MAP kinase signaling pathway; especially vismodegib, sorafenib, dabrafenib, incidences, sunitinib and others; average alopecia incidence >15%)
- Analgesics: Diclofenac, Indometacin, Ibuprofen, Naproxen.
- Antimycotics: Ketoconazole.
- Anticoagulants: systemic heparins, systemic coumarins.
- Antihypertensives: ACE inhibitors.
- Retinoids: vitamin A acid derivatives, e.g. acitretin, isotretinoin, tretinate.
- Lipid reducers: Fibrates such as clofibrate, fenofibrate, benzfibrate.
- Hormone preparations: Bromocriptine, androgens, anabolic steroids, clomiphene
- Antimalarials: chloroquine, hydroxychloroquine, mefloquine.
- Heavy metals: mercury, bismuth, gold, thallium.
- Neurological drugs: antiepileptic drugs (e.g. valproic acid), antidepressants, anticonvulsants, sedatives, Parkinson's drugs (e.g. levodopa).
- Others: Thyrostatic drugs (e.g. carbimazole), propranolol, butyrophenones, D-penicillamine, H2-blockers, amiodarone.
