Why Antifungals Matter
Antifungal medications treat infections caused by fungi, including yeast infections, athlete's foot, ringworm, and more serious systemic fungal infections. These medications appear in both OTC and prescription sections of the pharmacy, making them relevant to the PTCE Medications domain.
Topical Antifungals
Many common fungal infections are treated with topical preparations:
- Clotrimazole (Lotrimin) - available OTC for athlete's foot and yeast infections
- Miconazole (Monistat) - commonly used OTC for vaginal yeast infections
- Terbinafine (Lamisil) - available OTC as a cream for skin fungal infections
- Nystatin - a prescription topical and oral suspension used for various fungal infections
Oral Antifungals
More serious or widespread fungal infections may require oral treatment:
- Fluconazole (Diflucan) - commonly prescribed as a single-dose treatment for vaginal yeast infections or as a longer course for other fungal infections
- Terbinafine (Lamisil) - also available in oral form for nail fungal infections, which may require months of treatment
Key Points for the Exam
- Know common brand/generic pairs for frequently dispensed antifungals
- Understand that many antifungals are available OTC in topical forms
- Recognize that oral antifungals may require longer treatment courses
- Be aware that some oral antifungals can interact with other medications
Study Tip
Antifungals are a smaller drug class compared to antibiotics or cardiovascular drugs, so focused study can cover this category quickly. Learn the most common products in both topical and oral forms and their general uses.
