Doxycycline is a widely used antibiotic that effectively treats many bacterial infections, but like any medication, it may cause side effects. Most patients experience mild reactions such as nausea, headaches, or increased sensitivity to sunlight. These effects are temporary and often improve as the body adjusts to the medication.

More serious but less common side effects include esophageal irritation, persistent headaches, or liver-related symptoms. To minimize discomfort, patients should take doxycycline with a full glass of water, stay upright for at least 30 minutes after dosing, and use sunscreen when outdoors. If severe symptoms like difficulty breathing, intense rashes, or unexplained bruising occur, immediate medical attention is necessary.
