Drug allergies

Alternative names:

allergic reaction to a drug (medication)

Prevention:

There is no known way to prevent development of a drug allergy. In people who have a drug allergy, avoiding the medication is the best means to prevent an allergic reaction. In some cases, the medication may be given safely after pre-treatment with corticosteroids (such as prednisone), antihistamines (such as diphenhydramine), and/or epinephrine.
