• tell your doctor and pharmacist if you are allergic to doxycycline, minocycline, tetracycline, sulfites (for doxycycline syrup only), or any other medications.
• tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially antacids, anticoagulants ('blood thinners') such as warfarin (Coumadin), carbamazepine (Tegretol), penicillin, phenobarbital, phenytoin (Dilantin), and vitamins. Doxycycline decreases the effectiveness of some oral contraceptives; another form of birth control should be used while taking this drug.
• be aware that antacids, calcium supplements, iron products, and laxatives containing magnesium interfere with doxycycline, making it less effective. Take doxycycline 1 hour before or 2 hours after antacids (including sodium bicarbonate), calcium supplements, and laxatives containing magnesium. Take doxycycline 2 hours before or 3 hours after iron preparations and vitamin products that contain iron.
• tell your doctor if you have or have ever had diabetes or kidney or liver disease.
• tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking doxycycline, call your doctor immediately. Doxycycline can harm the fetus.
• if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking doxycycline.
• plan to avoid unnecessary or prolonged exposure to sunlight and to wear protective clothing, sunglasses, and sunscreen. Doxycycline may make your skin sensitive to sunlight.
• you should know that when you are receiving doxycycline for prevention of malaria, you should also use protective measures such as effective insect repellent, mosquito nets, clothing covering the whole body, and staying in well-screened areas, especially from early nighttime until dawn. Taking doxycycline does not give you full protection against malaria.
• you should know that when doxycycline is used during pregnancy or in babies or children up to age 8, it can cause the teeth to become permanently stained. Doxycycline should not be used in children under age 8 except for inhalational anthrax or if your doctor decides it is needed.
