Advise patients about drugs that are cross-reactive and about drugs that must be avoided. For example, penicillin allergy reactions have cross-reactivity with cephalosporins, phenytoin hypersensitivity syndrome has cross-reactivity with phenobarbital and carbamazepine, and sulfonamide reactions cross-react with other sulfa-containing drugs.

For patient education resources, see the Allergies Center.
