How are sexually transmitted infections (STIs) treated?

Many STIs are treated with antibiotics. Antibiotics are medicines that are given as a shot or taken by mouth.

If you are given an antibiotic to treat an STI, it's important that you take all of your medicine, even if the symptoms go away. Also, never take someone else's medicine to treat your illness. By doing so, you may make it more difficult to treat the infection. Likewise, you should not share your medicine with others.
