Flonaz 400 mg Tablet

Flonaz 400 mg Tablet is an oral antifungal medicine that contains 400 mg of fluconazole in each tablet. It belongs to the triazole antifungal class and is used to treat certain fungal and yeast infections. This strength is typically used when a doctor needs a higher fluconazole dose for a specific infection or treatment plan. It is taken by mouth as a tablet, making it a practical option for prescribed systemic antifungal therapy.

How it works: Fluconazole works by blocking a fungal enzyme needed to make ergosterol, an important part of the fungal cell membrane. Without that membrane support, the fungus cannot grow normally and dies off over time; the tablet form delivers the medicine into the body so it can work throughout the infection site.

Flonaz 400 mg Tablet is a higher-strength fluconazole tablet, so it is not meant for self-selection or casual use. A doctor may choose Flonaz 400 mg Tablet when a larger single dose or a higher daily dose is needed based on the infection being treated, your weight, kidney function, and other medicines you take. Compared with lower-strength fluconazole tablets, this 400 mg tablet is intended for patients who have already been assessed and need that specific dose.

• Treatment of certain yeast infections
• Treatment of some Candida infections
• Treatment of certain systemic fungal infections
• Prevention of fungal infection in selected patients
• Doctor-directed high-dose fluconazole therapy

• Swallow Flonaz 400 mg Tablet whole with water unless your doctor tells you otherwise.
• Take it exactly on the schedule prescribed; this strength may be given as a single dose or once daily depending on the infection.
• You may take it with or without food, since food does not usually change how fluconazole tablets work.
• Do not split, crush, or chew unless a clinician or pharmacist confirms it is appropriate for your prescription.
• If you miss a dose, take it when you remember unless it is almost time for the next dose; do not double up.
• Because this is a 400 mg tablet, do not use it to adjust doses on your own—your prescriber should decide the exact regimen.

Each Flonaz 400 mg Tablet provides 400 mg of fluconazole in one tablet. How often it is taken can vary a lot: some treatment plans use a single 400 mg dose, while others use 400 mg once daily or another doctor-directed schedule. The maximum daily amount depends on the condition being treated and your medical situation, so your prescriber should set the dose and duration specifically for you.

Do not change your dose or stop the medicine without speaking to your doctor.
