What is the most important information I should know about demeclocycline (Declomycin)?
You should not take this medication if you are allergic to demeclocycline or to similar antibiotics such as doxycycline (Adoxa, Alodox, Avidoxy, Oraxyl, Doryx, Oracea, Vibramycin), minocycline (Dynacin, Minocin, Solodyn), or tetracycline (Ala-Tet, Brodspec, Panmycin, Sumycin, Tetracap).
Demeclocycline 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 taking demeclocycline.
Demeclocycline passes into breast milk and may affect bone and tooth development in a nursing baby. You should not breast-feed while you are taking demeclocycline.
Do not give demeclocycline to a child younger than 8 years old. Demeclocycline can affect a child's growth or cause permanent yellowing or graying of the teeth.
Avoid exposure to sunlight or tanning beds. Demeclocycline can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.
Do not take iron supplements, multivitamins, calcium supplements, antacids, or laxatives within 2 hours before or after taking demeclocycline. Also avoid a product that contains bismuth subsalicylate (such as Pepto-Bismol) within 2 hours before or after taking demeclocycline. These medications can make it harder for your body to absorb demeclocycline.
Throw away any unused demeclocycline after the expiration date on the label has passed.
