Stop antibiotic: If you develop any rash after taking an antibiotic it is best to stop and call your dentist for a different drug.

Rash is Not OK: A rash is telling you that something is not well. It is very rare to see anybody show an allergic reaction to amoxicillin, however it can happen. The rash may be a result of something else that the patient is having happen at the same time. Therefore, it is good to have the dentist and/or physician evaluate what is occurring with this patient at this time.

No: Stop medication immediately and take diphenhydramine. This might be an allergic reaction to the medication. Allergy testing would be advisable to determine if the reaction is to the active ingredient itself or to some other inactive ingredient. In any case check with e prescribing doctor asap.

Dentist can prescribe a different (non-penicillin) antibiotic to reduce swelling and prevent spread of infection. The tooth, however, will require definitive dental treatment.
