What is the most important information I should know about doxycycline?

Do not use this medicine if you are pregnant. It could harm the unborn baby or cause permanent tooth discoloration later in life.

Doxycycline can make birth control pills less effective. Ask your doctor about using a non hormone method of birth control (such as a condom, diaphragm, spermicide) to prevent pregnancy while using doxycycline.

You should not take this medicine if you are allergic to doxycycline or to other tetracycline antibiotics such as demeclocycline (Declomycin), minocycline (Dynacin, Minocin, Solodyn, Vectrin), or tetracycline (Brodspec, Panmycin, Sumycin, Tetracap).

Before taking doxycycline, tell your doctor if you have liver disease, kidney disease, asthma, or if you are allergic to sulfites.

Drink plenty of liquids while you are taking doxycycline.

Children should not use doxycycline. Doxycycline can cause permanent yellowing or graying of the teeth in children younger than 8 years old.

Take this medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics.

Report Problems to the Food and Drug Administration
