Question: can ketoconazole cause erectile dysfunction?
Answer: Lesser-known drug types that can also cause such sexual problems include antihistamines such as diphenhydramine (Benadryl) and antifungal drugs such as ketoconazole (Nizoral). Surprisingly, heartburn drugs, including famotidine (Pepcid) and ranitidine (Zantac) are known to reduce sexual desire in men.
