General Info:

Tetracycline is a tetracycline antibiotic. It fights bacteria in the body.
Tetracycline is used to treat many different bacterial infections, such as urinary tract infections, acne, gonorrhea, and chlamydia, and others.
Tetracycline may also be used for purposes other than those listed in this medication guide.

Take all of the tetracycline that has been prescribed for you even if you begin to feel better. Your symptoms may start to improve before the infection is completely treated.
Children younger than 8 years of age should not take tetracycline. Tetracycline can cause permanent tooth discoloration and adversely affect growth.
Do not take iron supplements, multivitamins, calcium supplements, antacids, or laxatives within 2 hours of taking tetracycline. These products may decrease the effectiveness of tetracycline.
Tetracycline may decrease the effectiveness of birth control pills. Use a second method of birth control while taking tetracycline to ensure protection from unintended pregnancy.
Avoid prolonged exposure to sunlight or artificial UV light (e.g., tanning beds). Tetracycline may increase the sensitivity of the skin to sunlight, and severe burning may result. Wear protective clothing and sunscreen if exposure to the sun is unavoidable.
