Pfizer markets fluconazole under the brand name Diflucan. It’s an antifungal medication (a triazole) used to treat a variety of Candida infections and some other fungal infections. Generic fluconazole is also widely available.
What it’s used for (typical indications)
- Vaginal yeast infections (uncomplicated)
- Oropharyngeal and esophageal candidiasis
- Invasive candidiasis and other systemic Candida infections
- Certain other fungal infections (depending on local guidelines and clinician judgment)
- Prophylaxis in some immunocompromised patients (e.g., after certain transplants)
Forms you might see
- Oral tablets (e.g., 50 mg, 100 mg, 150 mg, 200 mg)
- Oral suspension
- Intravenous (IV) injection
Common dosing concepts (very general)
- Dosing depends on the specific infection and patient factors. For example, a single 150 mg dose is commonly used for uncomplicated vaginal candidiasis. Other infections require different regimens (often higher daily doses for longer periods). Always follow your clinician’s prescription and the product labeling.
- Fluconazole is dosed once daily for many infections, but your doctor will tailor this to your situation.
- People with kidney problems may need dose adjustments.
Safety, interactions, and cautions
- Tell your clinician about other medicines you take (warfarin, phenytoin, rifampin, cyclosporine, tacrolimus, oral hypoglycemics, etc.), as fluconazole can interact with many drugs.
- It can affect liver enzymes and rarely cause liver injury; seek care if you notice jaundice (yellowing of skin/eyes), dark urine, or severe abdominal pain.
- It can cause headaches, nausea, stomach pain, or skin rashes; severe allergic reactions are uncommon but require urgent care.
- Pregnancy: fluconazole is a pregnancy category C drug in general; use in pregnancy requires careful medical consideration. Discuss with your obstetrician if you’re pregnant or planning pregnancy.
- Avoid self-medicating for extended periods; use only as prescribed.
If you want, tell me:
- The infection you’re treating (or the indication you’re concerned about)
- Your location (so I can tailor availability and typical dosing guidance)
- Any medicines you’re taking or health conditions (renal/hepatic issues)
I can then give more specific dosing ranges, safety notes, or help you find the most relevant information.
