Doxycycline, while generally safe and effective, can cause side effects. Common ones include nausea, vomiting, diarrhea, and heartburn. These usually are mild and resolve without treatment. Drink plenty of water to minimize digestive upset.
More serious, though less frequent, side effects include increased sun sensitivity. Use sunscreen with an SPF of 30 or higher and limit sun exposure, especially during peak hours. This reduces your risk of sunburn.
Yeast infections are another possibility. If you notice any unusual vaginal discharge or itching, consult your doctor. Similarly, monitor for signs of a Clostridium difficile infection (C. diff), such as persistent diarrhea. Report any persistent or severe side effects immediately.
Before taking doxycycline, tell your doctor about all your medical conditions, including liver or kidney problems, and any medications you are taking, especially those affecting blood clotting or antibiotics. Pregnancy and breastfeeding also require special considerations – discuss these with your doctor before starting treatment.
Doxycycline can interact with certain medications, potentially reducing their effectiveness or increasing the risk of side effects. Inform your healthcare provider of all medications and supplements you use to ensure safe and effective use.
Finally, always follow your doctor’s instructions regarding dosage and duration of treatment. Do not stop taking doxycycline prematurely, even if you feel better, unless advised by your doctor.
