Explanation:

An allergic reaction to medication can range from mild to severe. Hives or a rash are common mild - moderate allergic manifestations. Difficulty breathing (not being able to breathe) is a severe, potentially life - threatening allergic reaction (anaphylaxis). Lack of appetite is not typically an allergic reaction symptom but could be a side - effect of some medications not related to allergy.
