Diflucan (Fluconazole): What It Treats and How to Use It Safely

One single 150 mg tablet of Diflucan often clears a vaginal yeast infection — but that quick fix doesn’t mean it’s the right choice every time. Diflucan (generic: fluconazole) is a widely used antifungal that treats many fungal infections, yet it can interact with other drugs, affect the liver, and isn’t safe in certain pregnancies. Know what it does, when to use it, and when to check with a clinician.

How Diflucan is commonly used and typical dosing

Fluconazole treats yeast infections in the mouth, throat, esophagus, vagina, and some systemic fungal infections. For uncomplicated vaginal yeast infections a single 150 mg oral dose is standard. For oral thrush or more serious infections, doctors usually prescribe daily doses (e.g., 100–200 mg) for one or more weeks. For severe systemic infections the dose and duration change a lot and need monitoring.

Don’t guess the dose: follow your prescriber. Missing doses or stopping early can let the fungus come back or become harder to treat. If symptoms don’t improve within 48–72 hours for simple infections, contact your healthcare provider.

Safety, interactions, and buying tips

Fluconazole is generally well tolerated but watch for these issues: liver injury (look for yellowing skin, dark urine), serious skin reactions, and heart rhythm changes in rare cases. If you have liver disease or take drugs that stress the liver, your doctor may choose a different treatment or monitor blood tests.

Drug interactions are common. Fluconazole can raise levels of warfarin, some statins, certain benzodiazepines, and many others. Always tell your clinician about all prescription drugs, OTC meds, and supplements you use. If you’re on warfarin or certain anti-arrhythmics, your clinician must check levels or pick another antifungal.

Pregnancy and breastfeeding: avoid single high doses of fluconazole in the first trimester unless a specialist advises it. For chronic or repeated use during pregnancy, doctors usually recommend alternatives. If you’re breastfeeding, talk with your prescriber — low levels pass into milk, but risks depend on dose and infant age.

Practical tips: keep a symptom diary, avoid unnecessary repeat doses, and don't treat recurrent infections alone — recurrent yeast infections (4+ a year) need medical evaluation for underlying causes like diabetes or immune issues. If you get a bad rash, swelling, jaundice, or fainting, stop the drug and seek urgent care.
