Side Effects and Precautions

Doxycycline monohydrate, while effective, can cause side effects. Common reactions include nausea, vomiting, diarrhea, and heartburn. These usually resolve without intervention. However, report persistent or severe digestive upset to your doctor immediately.

Sun Sensitivity

Doxycycline increases sun sensitivity. Avoid prolonged sun exposure and use high SPF sunscreen daily. Wear protective clothing, such as hats and long sleeves, during peak sun hours (10 AM to 4 PM).

Medication Interactions

This antibiotic interacts with several medications. Inform your doctor about all medications, supplements, and herbal remedies you are taking, including birth control pills, since doxycycline can reduce their effectiveness. Avoid antacids and dairy products, as these can hinder absorption.

Other Potential Side Effects

Less common but potentially serious side effects include yeast infections, allergic reactions (rash, itching, swelling), and esophageal irritation (difficulty swallowing). Seek medical attention if you experience any unusual symptoms.

Consult your physician before starting doxycycline if you are pregnant, breastfeeding, or have kidney or liver problems. They can determine if the benefits outweigh the risks for you.
