Diflucan (fluconazole): what it treats and how to use it safely

Need a quick, reliable guide to Diflucan? This page explains what Diflucan (fluconazole) does, common dosing patterns, side effects to watch for, and smart tips if you’re buying it online. No fluff — just the facts you can use when talking with your doctor or pharmacist.

What Diflucan treats and common doses

Diflucan is an oral antifungal medicine. Doctors prescribe it for vaginal yeast infections, oral thrush, skin and nail fungal infections, and more serious fungal illnesses. For uncomplicated vaginal yeast infections, a single 150 mg dose is a common one-time treatment. For oral thrush or recurrent infections, doctors often use daily doses like 100 mg until symptoms clear. Serious systemic infections may need higher or longer courses under specialist care.

Remember: doses vary with the illness, your weight, other health problems, and other medicines you take. Always follow your prescriber's instructions — and don’t self-adjust the dose based on web advice alone.

Side effects, interactions, and buying tips

Most people tolerate Diflucan well, but expect some mild side effects: headache, stomach upset, nausea, or a rash. More serious issues include liver problems (dark urine, yellowing skin or eyes) and changes in heart rhythm for people with certain heart conditions or who take QT‑prolonging drugs. If you notice worsening symptoms or signs of liver trouble, stop the drug and seek medical help.

Fluconazole can interact with common medicines — for example, blood thinners like warfarin, some anti-seizure drugs, certain cholesterol medicines, and some antidepressants. It can raise levels of these drugs and increase side effect risks. Tell your prescriber about every prescription, over-the-counter med, and supplement you take before starting Diflucan.

Pregnancy note: oral fluconazole is generally avoided in pregnancy unless a doctor says it’s necessary. If you’re pregnant or trying to conceive, ask your clinician for safer options.

Questions to ask your doctor or pharmacist: Is this the right antifungal for my infection? How long will I need to take it? Are there tests or blood checks needed while I’m on it? How might it interact with my other meds? A quick chat can prevent most problems.
