Terbinafine Use in Pregnancy

Introduction to Terbinafine Safety

• Onychomycosis and most dermatophyte infections are not life-threatening conditions and pose no risk to maternal or fetal health if left untreated during pregnancy, according to the British Journal of Dermatology 1, 2

Alternative Treatment Approaches

• For superficial fungal infections (not onychomycosis), topical antifungals are preferred, as suggested by the British Journal of Dermatology and Clinical Infectious Diseases 1, 2, 3, 4
• Avoid systemic azoles (itraconazole, fluconazole) during pregnancy due to established teratogenic risks, as recommended by the British Journal of Dermatology and Clinical Infectious Diseases 1, 2, 4

Critical Distinction from Other Antifungals

• Itraconazole is explicitly contraindicated in pregnancy, according to the British Journal of Dermatology 1, 2, 6
• High-dose fluconazole (400-800 mg/day) during the first trimester is associated with birth defects including craniosynostosis and skeletal abnormalities, as reported by the British Journal of Dermatology and Praxis Medical Insights 7

Systemic Therapy

• If systemic therapy is absolutely necessary for life-threatening fungal infection, amphotericin B is the drug of choice, as recommended by Clinical Infectious Diseases 4, 5
