No: Amoxicillin is a type of penicillin. You should not take it if you are sure that you are allergic to penicillin. Other pencillin drugs you need to avoid are ampicillin, ticaracillin, augmentin (amoxicillin and clavulanate) (amoxicillin-clavulanate), piperacillin, and sometimes cephalosporin antibiotics. You should see an allergist to help you out with by testing and clarifying the allergies.

A 24-year-old male asked:

I am allergic to penicillin notatum, would I be allergic to penicillin or amoxicillin?

Probably not: Penicillium notatum is a mold/fungi that if allergic, can cause symptoms like runny nose, sneezing, nasal congestion, worsening of asthma symptoms, etc. Penicillin antibiotics do not contain enough of the mold, and when ingested, would be a different reaction. To be safe, you could get tested for penicillin allergy with an allergist.
