Doxycycline, while effective in malaria prevention, can cause side effects. Common reactions include nausea, vomiting, diarrhea, and heartburn. These usually are mild and resolve without treatment. However, more serious reactions are possible.
Photosensitivity is a significant concern. Avoid prolonged sun exposure and use high SPF sunscreen. Sunburn can be severe with doxycycline.
Yeast infections (candidiasis) are another potential side effect, especially in women. This is due to changes in the gut flora.
Rare but serious side effects include: increased pressure in the skull (pseudotumor cerebri), liver problems, and esophageal irritation. Consult a doctor immediately if you experience severe abdominal pain, yellowing of skin or eyes (jaundice), or difficulty swallowing.
Certain groups should use caution. Pregnant or breastfeeding women should discuss risks and benefits with their physicians before taking doxycycline. It’s contraindicated in children under 8 years old. People with known allergies to tetracycline antibiotics should avoid it. Individuals with kidney or liver problems need careful monitoring.

Always inform your doctor of all medications you are taking, including herbal supplements, before starting doxycycline. This helps prevent potential drug interactions. Regular blood tests may be recommended during prolonged use. Adherence to the prescribed dosage is paramount for efficacy and minimizing risk.
