Cross-allergic reactions occur among the β-lactam antibiotics. To determine whether treatment with a β-lactam is safe when an allergy is noted, patient history regarding severity of previous reaction is essential.
Hypersensitive reactions are a major problem associated with the use of penicillin. A true allergy to penicillin is rare with an estimated frequency of anaphylaxis at 1-5 per 10 000 cases of penicillin therapy. Many adverse reactions will result in anaphylaxis, nausea, wheezing and laryngeal oedema. [16]
If the person is allergic to the family of antibiotics which both penicillin and amoxicillin are a part of (beta-lactam antibiotics), a first generation cephalosporin is used.
