From the FDA Drug Label
If you are pregnant, have diabetes, use birth control pills, or take antibiotics you may get yeast infections more often than other women
- Antibiotics can increase the chance of getting a yeast infection.
- The exact mechanism is not explicitly stated in the label, but it is mentioned that taking antibiotics may lead to an increased risk of yeast infections.
- It is likely that antibiotics disrupt the normal balance of bacteria in the vagina, allowing yeast to overgrow and cause an infection 1.
From the Research
Antibiotics can cause yeast infections by disrupting the natural balance of microorganisms in the body, leading to an overgrowth of yeast, particularly Candida albicans. When you take antibiotics to treat bacterial infections, these medications don't just kill harmful bacteria but also beneficial bacteria that normally keep yeast in check [ 2 ]. Without this natural competition, yeast can multiply rapidly, especially in warm, moist areas like the vagina, mouth, or digestive tract.
Key Points to Consider
- Common antibiotics that may trigger yeast infections include broad-spectrum antibiotics like amoxicillin, doxycycline, and ciprofloxacin.
- If you're prone to yeast infections while taking antibiotics, preventive measures can help, such as taking probiotics (containing Lactobacillus) during and after antibiotic treatment [ 3 ].
- Maintaining good hygiene, wearing cotton underwear, and avoiding douching can also reduce the risk of developing a yeast infection.
- For those experiencing symptoms like itching, burning, unusual discharge, or redness, over-the-counter antifungal treatments such as fluconazole (Diflucan) or topical miconazole (Monistat) can effectively treat the infection.
Important Considerations
The risk of developing a yeast infection varies among individuals, with some people being more susceptible due to factors like diabetes, pregnancy, or compromised immune systems [ 2 ]. It is essential to be aware of these factors and take preventive measures to minimize the risk of yeast infections when taking antibiotics.
