Correct answer: DDo not dispense and contact the prescriber for a non-penicillin alternative

Lip swelling and wheeze after co-amoxiclav suggest an immediate beta-lactam allergy. Amoxicillin is a penicillin and should not be supplied without prescriber review. Giving the first dose in the pharmacy is unsafe because anaphylaxis risk exists. Flucloxacillin is also a penicillin, so it is not an appropriate pharmacist substitution.
