How are drug allergies treated?
The primary goal when treating drug allergies is symptom relief. Symptoms such as rash, hives, and itching can often be controlled with antihistamines, and occasionally corticosteroids. For coughing and lung congestion, drugs called bronchodilators may be prescribed to widen the airways. For more serious anaphylactic symptoms — life-threatening allergic reactions including difficulty breathing or loss of consciousness — epinephrine may be given. Occasionally, desensitization is used for penicillin allergy. This technique decreases your body’s sensitivity to particular allergy-causing agents. Tiny amounts of penicillin are injected periodically in increasingly larger amounts until your immune system learns to tolerate the drug. If you are severely allergic to certain antibiotics, there are alternative antibiotics your doctor can prescribe.
