Tetracycline is a popularly prescribed antibiotic efficient in treating such conditions as acne, urinary tract infections, gonorrhea, chlamydia and others as directed by your health care professional. Taking tetracycline and breastfeeding a baby is not recommended as your nursing infant is likely to experience permanent tooth discoloration in the future. Tetracycline passes into breast milk and must not be taken by breastfeeding women unless otherwise advised by their health care provider. Tetracycline can increase the sensitivity of your skin, which means you will be more likely to have bad sunburn. It’s recommended to wear sunglasses, put on sunscreen and try not to stay outside for a long time if it’s sunny.

Certain supplements or vitamins you are also taking are likely to make tetracycline less effective. These include laxatives, antacids, multivitamins and supplements containing iron or calcium. Do not use this drug past its expiration date as this is fraught with serious damage to your kidneys. A relapse of infection is possible if you do not take the entire amount of tetracycline prescribed to you. Even thought your symptoms may improve the bacteria may still be there and your body will not be able to deal with it.
