A
Drug and food allergies are also Type I hypersensitivity. Any drug potentially may cause a drug reaction, but common ones include penicillin, cephalosporins, codeine, pain medications, vaccines, and local anesthetics. Reactions vary from mild to severe. Usually, symptoms do not occur until the client has taken several doses of the medication, although they can occur at first exposure. The most common reaction is the sudden development of a bright red, itchy rash, often appearing initially on the trunk or arms. Occasionally, a client may develop an anaphylactic reaction.
