Just had a tooth removed and it seems infected. whats good over-the-counter medication?

Gentle rinse: No over the counter meds will fix your problem if it really is infected. Try warm salt water, gently rinsing. You may have what is called a dry-socket. Call your dentist to re-check the site and make sure that you are healing properly.

Advil/allieve: Otc's are good for discomfort, however, if you truly have an infection you should be on something stronger than otc's.

Infection : Infections need to be treated with antibiotics and these require a prescription from a dentist.

None: You need to return to the dentist or removed it to have it checked before the infection becomes more serious.

Professional opinion: When you say "it seems infected, " may be your assessment and maybe everything is just healing. But don't take chances, get back to the dentist or oral surgeon to make sure.
