Penicillin family



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


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.
