How long after i take claritin (loratadine) should my allergy swelling go down?
A doctor has provided 1 answer
Couple of hours: Antihistamines can help with the itching and swelling that accompany allergic reactions. If the swelling is significant, it may take several hours to a day or so. For milder symptoms, Loratadine may begin to help in 1-2 hours.
