Is there an over-the-counter medicine for chylmidia?

No: Some docs will offer partner treatment without exam after the primary case is diagnosed. However, since this can be acquired the same way and at the same time as other STD's like gonorrhea. This doesn't respond to the chlamydia treatment, so it is best to have a real evaluation. Untreated gonorrhea can have few or no symptoms but still make you sterile.
