Doxycycline is not a primary treatment for yeast infections, which are typically caused by Candida species. Antifungal medications are the standard treatment for vaginal yeast infections [1].
Why Isn't Doxycycline Used for Yeast Infections?
Doxycycline is an antibiotic that targets bacteria, not fungi [2]. Yeast infections are fungal overgrowths, and antibiotics like doxycycline can sometimes disrupt the natural balance of microorganisms in the body, potentially leading to a yeast infection as a side effect rather than treating it [3].
What Medications Treat Yeast Infections?
Common treatments for yeast infections include antifungal medications such as fluconazole (Diflucan), clotrimazole, and miconazole [1]. These are available in oral or vaginal suppository/cream forms [1].
Can Doxycycline Cause a Yeast Infection?
Yes, antibiotics like doxycycline can increase the risk of developing a yeast infection. By killing off beneficial bacteria that normally keep Candida in check, antibiotics can allow yeast to multiply unchecked [3].
When Should You See a Doctor for a Yeast Infection?
Consult a healthcare provider if you have a yeast infection that doesn't improve with over-the-counter treatments, if you experience recurrent infections, or if you are unsure if your symptoms are indeed a yeast infection [1].
