Doxycycline, while effective for treating bacterial infections, can cause several side effects. Many are mild and temporary, but some require medical attention. Let’s review the most common ones.
Gastrointestinal Issues
Upset stomach, nausea, vomiting, and diarrhea are frequently reported. These usually subside as your body adjusts to the medication. Drink plenty of water and consider taking doxycycline with food to minimize these effects. Severe or persistent diarrhea, however, requires immediate medical attention as it could indicate a serious complication.
Sun Sensitivity
Doxycycline increases your skin’s sensitivity to sunlight. Limit sun exposure, wear protective clothing, and use sunscreen with a high SPF (at least 30) when outdoors. Sunburns are more likely and can be more severe while taking this antibiotic. Severe sunburn requires prompt medical attention.
Other Potential Side Effects
While less common, you might experience yeast infections (especially in women), headaches, dizziness, or changes in your skin color. Rarely, more serious side effects like increased pressure in your skull or liver problems can occur. These require immediate medical attention.
