What is Fluconazole?
Fluconazole is an oral antifungal thatโs prescribed โoff-labelโ for tinea versicolor, a condition that causes discolored skin patches. โOff-labelโ use simply means that the medication is prescribed in a different way than what itโs licensed for – in this case, for a different condition. Your physician will only prescribe this medicine, though, if thereโs enough evidence supporting its effectiveness and if they think itโs the most appropriate treatment for you.
Although you donโt always need treatment for tinea versicolor, the discoloration can make people self-conscious.
Topical treatments are usually recommended as the first choice, but if they are ineffective, oral antifungals like fluconazole may be prescribed.
How does Fluconazole work?
Fluconazole stops the production of ergosterol, an important component of the fungal cell membrane. Without it, the fungi struggle to survive, causing holes to appear in the fungal cell wall. This causes the contents of the fungus to leak out, which eventually leads to their expiration, helping clear the infection from the body.[1]
Will I get side effects using Fluconazole?
Yes, thereโs a chance of getting side effects when taking Fluconazole, although not everyone will get them. The most common side effects include:
- Headache
- Stomach discomfort
- Diarrhea
- Vomiting
- Nausea
- Rash
The side effects should subside once you stop taking Fluconazole, but if they worsen or persist, consult your doctor.
For the full list of side effects, check the package insert that comes with your medicine.
Can I get Fluconazole over the counter?
No, you canโt get Fluconazole without seeing a medical professional first. Fluconazole is only available with a prescription from a clinician.
What doses of Fluconazole are there?
Fluconazole comes as a 50 mg dose. Alternatively, you may be advised to take 300 mg to 400 mg once weekly for up to 12 weeks (usually two to four). But this may depend on the severity of your infection, and whether previous courses of treatment have been unsuccessful.
