Patient Information: Drink plenty of fluids along with doxycycline to reduce risk of esophageal irritation and ulceration.
Food, especially those which contain calcium, reduces absorption of tetracycline. However, doxycyline's absorption is not markedly influenced by simultaneous ingestion of food or milk.
Avoid excessive sunlight or artificial ultraviolet light while taking doxycycline. Discontinue therapy if phototoxicity occurs.
Chronic doxycycline use increases incidence of vaginal candidiasis.
