The standard dosage of fluconazole for the treatment of cryptococcal meningitis is 400 mg, followed by 200 mg daily for 10 to 12 weeks. The recommended amount for preventing fungal infections in adults undergoing bone marrow transplantation is 400 mg once daily. For the treatment of fungal infections, dosing will vary, depending on the specific type of infection.
The dose of fluconazole (Diflucan®) your healthcare provider recommends will vary, depending on a number of factors, including:
- The medical condition being treated
- Your age and weight (for children)
- Other medications you are taking
- Other medical conditions you may have.
As is always the case, do not adjust this amount unless your healthcare provider specifically instructs you to do so.
The medication is available in the following strengths and forms:
- Fluconazole 50 mg tablets
- Fluconazole 100 mg tablets
- Fluconazole 150 mg tablets
- Fluconazole 200 mg tablets
- Fluconazole powder for oral suspension (which is mixed by a pharmacist to a concentration of 10 or 40 mg per mL, depending on the strength)
- Fluconazole 2 mg per mL injection (available in various package sizes).
Interestingly, the recommended dosages are the same for the oral forms and the injectable forms, since the medication is absorbed well when taken by mouth.
Dosing for Vaginal Yeast InfectionsThe standard dose of fluconazole for treating vaginal yeast infections in adults is a single dose of 150 mg taken by mouth. Unlike most other yeast infection medications, fluconazole is not used vaginally. It works through the bloodstream to treat yeast infections.
