Infections that occur because of bacteria can be effectively treated with Tetracycline. The drug is an antibiotic which cures a number of bacterial infections that affect the skin, urinary tract, intestines, genitals, respiratory tract, lymph nodes and various other parts of the body. The drug is also useful in the treatment of acne and sexually transmitted diseases (STD’s) like chlamydia, gonorrhea as well as syphilis. In cases of some patients who cannot be prescribed penicillin or any other antibiotic for the treatment of severe infections like anthrax and listeria, Tetracycline is prescribed instead.

The medicine should be taken exactly as prescribed by the doctor. Take it about an hour or 2 after you take your meal. The drug should not be consumed with milk or for that matter any other dairy products unless specifically advised by the doctor. This is primarily because dairy products make it difficult for the body to absorb Tetracycline. The drug will only treat bacterial infections, it cannot be taken for the treatment of viral infections like cold or flu.

Some facts should be kept in mind when taking this drug. For instance, children below the age of 8 years cannot be given this medicine.

It may also lead to discolored teeth in the child which will be permanent. Lactating mothers should also take their doctors advice before using Tetracycline. It is also important that you throw away expired Tetracycline, as consumption of the drug can lead to severe kidney problems.
