Doxycycline, while effective for some bacterial infections, can cause side effects. These vary in severity and frequency. Common side effects include nausea, diarrhea, and vomiting. These usually are mild and resolve without treatment. However, you should contact your doctor if they persist or worsen.
Gastrointestinal Issues
Besides nausea, diarrhea, and vomiting, some individuals experience abdominal pain or heartburn. Taking doxycycline with food can often mitigate these issues. Drink plenty of water while taking the medication.
Sun Sensitivity
Doxycycline increases your sun sensitivity. Severe sunburn can result from even brief sun exposure. Use sunscreen with a high SPF (30 or higher), wear protective clothing, and limit sun exposure while taking this antibiotic and for a few days after completing the course.
Other Potential Side Effects
Less common, but still possible, side effects include vaginal yeast infections, headache, dizziness, and photosensitivity (skin sensitivity to light). Rarely, more serious reactions such as difficulty breathing, swelling of the face, lips, tongue, or throat, and severe skin reactions occur. Seek immediate medical attention if you experience any of these severe side effects.
Medication Interactions
Doxycycline can interact with other medications. Always inform your doctor and pharmacist about all medications, including over-the-counter drugs and supplements, you are taking. This helps prevent potential drug interactions.
