While doxycycline is generally well-tolerated, some individuals may experience side effects. These are usually mild and temporary, but it’s crucial to be aware of them.
- Gastrointestinal issues: Nausea, vomiting, diarrhea, or heartburn are common. These usually subside as your body adjusts to the medication. Consider taking doxycycline with food to minimize stomach upset. Photosensitivity: Doxycycline can increase your skin’s sensitivity to sunlight. Wear sunscreen with a high SPF, protective clothing, and limit sun exposure, especially during peak hours. Yeast infections: Doxycycline can disrupt the natural balance of bacteria in your body, potentially leading to yeast infections. Watch for symptoms like vaginal itching or discharge. Skin reactions: Rash, itching, or hives are possible. If you develop a severe allergic reaction, discontinue use immediately and seek medical attention.
Less common, but still possible, side effects include:
