Antifungal

What Are Antifungal? 

Fungal infections affect over 1 billion people globally, ranging from common superficial infections (ringworm, athlete’s foot, vaginal thrush) to life-threatening invasive mycoses in immunocompromised patients. AmozonPill stocks 76 generic antifungal medications covering azoles, allylamines, polyenes, and topical agents — sourced from FDA-inspected, WHO-GMP manufacturers at up to 95% below brand-name prices. 

Drug Classes Available 

• Azoles (Triazoles): Fluconazole, Itraconazole, Voriconazole, Posaconazole — inhibit ergosterol synthesis, disrupting the fungal cell membrane. Used for Candida, Aspergillus, Cryptococcus, and dermatophyte infections. 
• Allylamines: Terbinafine, Naftifine — inhibit squalene epoxidase, causing ergosterol depletion. Highly effective for dermatophyte infections: onychomycosis (nail fungus), tinea pedis, and tinea corporis. 
• Imidazoles (Topical): Clotrimazole, Miconazole, Ketoconazole — available as creams, gels, and shampoos. First-choice for localised skin and vaginal candidiasis and tinea infections. 
• Polyenes: Amphotericin B (oral suspension), Nystatin — bind ergosterol, forming pores in the fungal membrane. Nystatin is used for oral and intestinal candidiasis; oral Amphotericin B is non-absorbed and used for GI fungal overgrowth.

How to Choose the Right Product 

For vaginal thrush (acute): Fluconazole 150 mg single dose is the easiest and most effective oral treatment. For onychomycosis (nail fungus): Terbinafine 250 mg daily for 6 weeks (fingernail) or 12 weeks (toenail) is first-line. For recurrent or severe oral/oesophageal Candida: Fluconazole 100–200 mg daily. For skin dermatophyte infections: a topical antifungal cream (Clotrimazole, Miconazole) is usually sufficient. For invasive or systemic fungal infections: specialist-prescribed Voriconazole or Posaconazole. 

Frequently Asked Questions

What is the fastest treatment for a vaginal yeast infection? 

A single oral dose of Fluconazole 150 mg clears most uncomplicated vaginal Candida infections within 1–3 days. Topical Clotrimazole 500 mg pessary is an equally effective single-dose option. 

How long does it take for nail fungus treatment to work? 

Terbinafine is taken for 6 weeks (fingernails) or 12 weeks (toenails), but clear nail growth takes 6–18 months as the nail grows out. Cure rates for toenail onychomycosis are approximately 70–80% with Terbinafine. 

What is the difference between Fluconazole and Itraconazole? 

Fluconazole has excellent Candida coverage but limited mould activity. Itraconazole has broader spectrum including Aspergillus and dermatophytes, and is preferred for nail fungus and moulds. It requires food for absorption and has more drug interactions. 

Can antifungals be used during pregnancy? 

Topical antifungals (Clotrimazole, Miconazole) are considered safe during pregnancy. Oral Fluconazole, particularly at doses above 150 mg, has been associated with foetal risk and should be avoided. Always consult your obstetrician before using any antifungal while pregnant. 

Why does ringworm keep coming back despite treatment? 

Recurrence usually means incomplete treatment (course too short), re-exposure from the environment or infected contacts, or undiagnosed coexisting nail infection that re-seeds the skin. Ensure shared footwear, towels, and surfaces are disinfected alongside treatment. 

Does Ketoconazole shampoo work for scalp fungal infections? 

Yes. Ketoconazole 2% shampoo is effective for tinea capitis (scalp ringworm) and seborrhoeic dermatitis caused by Malassezia. It is used 2–3 times weekly as maintenance or during active infection.
