Tetracycline can be used for people with bacteria-induced infections helping the immune system to deal with this condition. It is most often prescribed for urinary tract infections, but can be also used for other conditions as recommended by your health care provider. Tetracycline is not for use in children younger than 8 as their growth can be affected, and they can have graying or yellowing of their teeth. If you think your child needs to take this drug and he or she is younger than 8 talking to your doctor is strongly recommended. You must make sure the benefits of such treatment outweigh potential health risks. Taking this medicine during pregnancy can cause dangerous health effects in an unborn baby. Pregnant women must notify their doctor of their condition before they are prescribed this drug.
During the whole period of treatment try to avoid being exposed to direct sunlight or sunlamps as you are more likely to get sunburn. Make sure you apply sunscreen with a high sun protection factor and wear clothes that cover your skin as much as possible. If you are allergic to tetracycline or similar drugs (demeclocycline, doxycycline or minocycline) you must not start to take it to avoid an allergic reaction.
