Fluconazole 150 mg: Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions

What Is Fluconazole 150 mg?

Fluconazole 150 mg is a prescription antifungal medication used to treat infections caused by fungi, especially infections caused by Candida species. It belongs to a group of medicines called azole antifungals.

Fluconazole works by stopping fungi from producing ergosterol, an essential component of fungal cell membranes. Without ergosterol, fungal cells become damaged and are unable to grow or survive.

Fluconazole 150 mg is commonly used as a single-dose treatment for vaginal thrush (vulvovaginal candidiasis), although the dosage and duration depend on the type and severity of infection.

How Fluconazole Works

Fungi need a healthy cell membrane to survive.

Fluconazole works by:

• Blocking the fungal enzyme responsible for making ergosterol.
• Weakening fungal cell membranes.
• Preventing fungal growth and reproduction.
• Helping the body’s immune system clear the infection.

It targets fungi rather than bacteria, meaning it is not effective against bacterial infections.
