SIDE EFFECTS: The most common side effects of terbinafine are:
Oral terbinafine can cause liver failure sometimes leading to liver transplantation or death.
PRESCRIPTION: Yes (Tablets), OTC (Topical preparations)
GENERIC AVAILABLE: Yes
PREPARATIONS: Tablets: 250 mg. Oral Granule: 125 and 187.5 mg. Cream, Gel, solution, or spray: 1%.
STORAGE: All formulations should be stored at room temperature, 15 C - 30 C (59 F - 86 F).
DRUG INTERACTIONS: Rifampin reduces oral terbinafine blood concentrations, potentially reducing the efficacy of terbinafine. Cimetidine (Tagamet) may increase oral terbinafine blood levels, potentially increasing side effects of terbinafine. Fluconazole (Diflucan) increases the blood levels of oral terbinafine by 52%-69%. Potentially leading to increased side effects.
PREGNANCY: There are no adequate studies in pregnant women. Since nail fungus treatment can be delayed until after pregnancy there is no reason to use oral terbinafine during pregnancy.
NURSING MOTHERS: Breastfeeding mothers should not use oral terbinafine because terbinafine passes into breast milk.
