Doxycycline can cause intestinal symptoms, vaginal yeast infections in women, and sensitivity to sunlight, resulting in a sunburn-like reaction in a small percentage of people. People should take it with a full glass of liquid and should not lie down for several hours to ensure that the drug reaches the stomach.
