What Is the Treatment for a Drug Allergy?
Patient Comment Read 1 Comment
The main treatment for drug allergy is stopping the suspected drug. Mild reactions may be treated at home. For itching, an antihistamine such as diphenhydramine (Benadryl), cetirizine (Zyrtec), or fexofenadine (Allegra) may be recommended. For more involved skin symptoms, sometimes oral steroids (prednisone) may be indicated.
Moderate to severe reactions require immediate medical attention. Some severe hypersensitivity reactions may require hospitalization. Anaphylaxis to a drug needs to be treated quickly with epinephrine. Patients with anaphylaxis need monitoring for an appropriate time period after the reaction. They are usually treated with steroids and antihistamines, as well. Other severe skin reactions or drug reactions with other organ involvement may require hospitalization and directed treatment. Also steroids may be necessary for treatment.

Drug eruptions can mimic a wide range of dermatoses. The morphologies are myriad and include morbilliform (most common, see Media file 1), urticarial, papulosquamous, pustular, and bullous. Medications can also cause pruritus and dysesthesia without an obvious eruption.
