What is tetracycline?

Tetracycline is an antibiotic that's used to treat a variety of bacterial infections and other conditions. It may be used to treat upper respiratory infections, pneumonia, typhus fever, Rocky Mountain spotted fever, gonorrhea and urinary tract infections. It also may be used to treat conjunctivitis (pink eye) and other eye infections. Sometimes, tetracycline is used to treat severe acne. Tetracycline works by decreasing bacteria's ability to make certain proteins that it needs to live. This helps kill bacteria and eliminate the infection. Tetracycline is available as a capsule that is to be taken by mouth with a full glass of water. This medication works best when taken on an empty stomach, so take it one to two hours before or after meals. Your dosage of medication will depend on what condition you're treating, but always take tetracycline as your doctor prescribes. This means that even if you're feeling better, you should continue taking tetracycline for the full amount of time your doctor recommends. There are several generic versions of tetracycline.
