I got bit by my cat last night the area is now red and swollen. what type of medicine will they give me for this?

This is an infected cat bite and requires prompt treatment with appropriate antibiotics to avoid septicemia. I recommend proceeding to the ER ASAP as you may need IV antibiotics in view of the redness& swelling of the wound. Your cat has most likely had its rabies shot. You may need a tetanus booster. You'll need follow-up care for this infection. The ER MD will decide on the best antibiotic
