Antihistamines such as Astemizole and Cetirizine provide relatively rapid relief from pruritus; noticeable itch relief typically occurs within 30 minutes of oral administration. Combining these with topical medications further enhances efficacy. Once pruritus symptoms improve, maintenance therapy may include oral calcineurin inhibitors to help prevent recurrence of itching.
