Potential Side Effects and Adverse Reactions

Doxycycline, even at a high dosage like 200mg twice daily, can cause various side effects. These reactions vary in severity and frequency.

Common side effects include nausea, vomiting, diarrhea, and heartburn. These are usually mild and often resolve without intervention. However, persistent or severe gastrointestinal upset warrants contacting your doctor.

Sun sensitivity is another potential concern. Increased risk of sunburn necessitates using sunscreen with a high SPF and limiting sun exposure, especially during peak hours.

Yeast infections (candidiasis) may occur, particularly in women. Symptoms include vaginal itching and discharge. Treatment might be required if these symptoms develop.

Less frequent but more serious side effects include allergic reactions (rash, hives, swelling), increased pressure in the brain (pseudotumor cerebri), and liver problems. Seek immediate medical attention if you experience any severe allergic reaction or signs of liver dysfunction (jaundice, dark urine, abdominal pain).

Medication interactions are possible. Inform your doctor about all medications, supplements, and herbal remedies you are taking to minimize potential risks.

This information does not cover all possible side effects. Always consult your healthcare provider for personalized advice and to discuss any concerns.
