Before taking Demeclocycline

You should not use demeclocycline if you are allergic to demeclocycline or similar antibiotics such as doxycycline, minocycline, or tetracycline.

Tell your doctor if you have ever had:

liver or kidney disease;

diabetes; or

lupus.

If you are using demeclocycline to treat gonorrhea, your doctor may test you to make sure you do not also have syphilis, another sexually transmitted disease.

Do not use if you are pregnant. Taking demeclocycline during the second or third trimester of pregnancy may cause bone growth problems in the unborn baby, or permanent tooth discoloration later in life.

Demeclocycline can make birth control pills less effective. Ask your doctor about other birth control options such as an injection, implant, skin patch, vaginal ring, condom, diaphragm, cervical cap, or contraceptive sponge.

Demeclocycline can pass into breast milk and may affect bone and tooth development in a nursing infant. Do not breastfeed while you are taking doxycycline.

Children younger than 8 years old should use demeclocycline only for infections that cannot be treated with a safer antibiotic. Demeclocycline can affect a child's growth or cause permanent yellowing or graying of the teeth.
