Amoxicillin is an antibiotic used to treat bacterial infections. The drug comes in many different forms, including capsules, tablets, and liquid. One of the common side effects of amoxicillin is a skin rash.

Amoxicillin comes from penicillin, which is known to cause allergic reactions in some people.

An amoxicillin rash can be mild or severe, depending on how sensitive the individual is to the medication.

It can be red or purple and can spread across the body. Amoxicillin rash may also show up as hives, which are red or white bumps that develop on the skin. Or, it may appear as a maculopapular rash with areas that resemble flat, red patches.
