By Mayo Clinic staffIf ringworm of the body covers a large area, is severe or doesn't respond to over-the-counter medicine, you may need a prescription-strength topical medication (lotion, cream or ointment) or an oral medication (pill, capsule or tablet). Many options are available, including:
Topical
- Butenafine (Mentax)
- Ciclopirox (Loprox)
- Econazole
- Miconazole (Monistat-Derm)
- Oxiconazole (Oxistat)
- Terbinafine (Lamisil)
Oral
- Itraconazole (Sporanox)
- Fluconazole (Diflucan)
- Ketoconazole (Nizoral)
- Terbinafine (Lamisil)
Side effects from oral medications include gastrointestinal upset, rash and abnormal liver functioning. Taking other medications, such as antacid therapies for ulcer disease or gastroesophageal reflux disease (GERD), may interfere with the absorption of these drugs taken for ringworm. Oral medications for ringworm may alter the effectiveness of warfarin, an anticoagulant drug that decreases the clotting ability of your blood.
