Are you based in the US? In the US, you Can
't purchase antibiotics
with a prescription. If you Can
purchase over the counter, it would depend on what you're allergic too but amoxicillin (similar to penicillin) would probably work. If the wisdom teeth are just inflamed and
its not an infection though, trying to keep the area clean and
placing ice on it while its "teething" would be a better solution than antibiotics
as the antibiotics
would do nothing for the inflammation.
