Doxycycline is a tetracycline antibiotic that fights bacteria in the body.
Doxycycline is used to treat many different bacterial infections, such as acne, urinary tract infections, intestinal infections, respiratory infections, eye infections, gonorrhea, chlamydia, syphilis, periodontitis (gum disease), and others.
Doxycycline is also used to treat blemishes, bumps, and acne-like lesions caused by rosacea. It will not treat facial redness caused by rosacea.
Some forms of doxycycline are used to prevent malaria, to treat anthrax, or to treat infections caused by mites, ticks, or lice.
You should not take doxycycline if you are allergic to any tetracycline antibiotic.
Children younger than 8 years old should use doxycycline only in cases of severe or life-threatening conditions. This medicine can cause permanent yellowing or graying of the teeth in children.
Using doxycycline during pregnancy could harm the unborn baby or cause permanent tooth discoloration later in the baby's life.
You should not take this medicine if you are allergic to doxycycline or other tetracycline antibiotics such as demeclocycline, minocycline, tetracycline, or tigecycline.
To make sure doxycycline is safe for you, tell your doctor if you have ever had:
liver disease;
kidney disease;
asthma or sulfite allergy;
increased pressure inside your skull; or
if you also take isotretinoin, seizure medicine, or a blood thinner such as warfarin (Coumadin).
If you are using doxycycline to treat chlamydia, your doctor may test you to make sure you do not also have gonorrhea, another sexually transmitted disease.
Taking this medicine during pregnancy may affect tooth and bone development in the unborn baby. Taking doxycycline during the last half of pregnancy can cause permanent tooth discoloration later in the baby's life. Tell your doctor if you are pregnant or if you become pregnant while using this medicine.
Doxycycline can make birth control pills less effective. Ask your doctor about using a non-hormonal birth control (condom, diaphragm with spermicide) to prevent pregnancy.
Doxycycline can pass into breast milk and may affect bone and tooth development in a nursing infant. The extent of absorption is unknown. Do not breastfeed while you are taking this medicine.
Children should not use this medicine. Doxycycline can cause permanent yellowing or graying of the teeth in children younger than 8 years old.
Children should use doxycycline only in cases of severe or life-threatening conditions such as anthrax or Rocky Mountain spotted fever. The benefit of treating a serious condition may outweigh any risks to the child's tooth development.
Do not take iron supplements, multivitamins, calcium supplements, antacids, or laxatives within 2 hours before or after taking doxycycline.
Avoid taking any other antibiotics with doxycycline unless your doctor has told you to.
Avoid exposure to sunlight or tanning beds. Doxycycline can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.
Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.
Get emergency medical help if you have any signs of an allergic reaction to doxycycline: (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning in your eyes, skin pain, red or purple skin rash that spreads and causes blistering and peeling).
Seek medical treatment if you have a serious drug reaction that can affect many parts of your body. Symptoms may include: skin rash, fever, swollen glands, flu-like symptoms, muscle aches, severe weakness, unusual bruising, or yellowing of your skin or eyes. This reaction may occur several weeks after you began using doxycycline.
