Doxycycline Precautions

 Some people develop secondary infections while taking Doxycycline. Some patients will experience overgrowth of colon bacteria which can cause diarrhea ranging from mild to life threatening. If you begin having diarrhea, call your doctor. Doxycyclin may cause patients to be more sensitive than usual to sun exposure. Tell your doctor if you develop a rash while using Doxycycline.
