Doxycycline is used to treat and prevent infections, and sometimes for other conditions.
Take doxycycline regularly as directed until the course is finished. Take it with food.
Doxycycline can damage the oesophagus (food pipe). To avoid this, take it with a large glass of water. Swallow the tablet whole, do not crush or chew it. Sit or stand upright for at least 30 minutes after taking a dose.
Take the missed dose as soon as possible and continue as directed.
Some medicines available without a prescription may react with doxycycline including:
