Question:

what medicines are in the pennicillin family that you should not take if you are allergic to pennicillin?

Answer:

If you are allergic to penicillin or related drugs, you should avoid penicillin all beta-lactam antibiotics. This is a class of antibiotics that will react in people with a penicillin allergy. Common drugs include Penicillin, Pen V, Amoxicillin, Augmentin and many, many others. I can't provide a complete list, but I can suggest that you talk with your doctor or pharmacist about a medicine that is prescribed to find out if it is safe to take. Some persons with a penicillin allergy will tolerate a type of medication called a cephalosporin, others will have an allergic reaction. You should ask your doctor if it is safe for you to take a cephalosporin antibiotic.
