Fluconazole typically starts working within 24 hours, especially for mild vaginal yeast infections, with noticeable symptom improvement such as reduced itching and irritation. However, full relief and clearance of the infection can take 3 to 7 days, sometimes up to a week. For more severe or recurring infections, it may take longer, and treatment might involve multiple doses over several days or weeks.
How Fluconazole Works
Fluconazole is an antifungal medication that works by stopping the growth of fungi, specifically by inhibiting the production of ergosterol, an essential component of the fungal cell membrane. This leads to the death of the fungal cells and helps clear the infection.
Timeline for Symptom Relief
- Mild vaginal yeast infections: Symptom relief often begins within 24 to 48 hours after a single 150 mg dose.
- Oral thrush or more serious infections: May require treatment for up to 14 days or longer.
- Severe or systemic fungal infections: Could take weeks or months with higher doses and sustained treatment.
Additional Considerations
Individual factors such as immune system strength, underlying health conditions (e.g., diabetes, kidney disease), and the type and severity of infection also influence how fast fluconazole works.
In summary, people usually start to feel better within the first day or two of taking fluconazole, but completing the full course of treatment as prescribed is essential for completely clearing the infection.
