Urticaria caused by drug allergy requires immediate discontinuation of the offending drug, followed by substitution with an alternative medication. Next, under a physician’s guidance, topical medications may be applied to relieve pruritus—commonly used agents include calamine lotion or topical corticosteroid creams, such as triamcinolone acetonide cream or hydrocortisone cream. For severe pruritus, oral antihistamines may also be prescribed.
