Itching scalp and ears appear to be related to taking Allegra. It began last summer (2002) after starting Allegra for hayfever and allergies, but I didn't make the connection. Didn't take Allegra from approximately November, 2002 until April, 2003, and in hindsight, itch almost totally gone. Started on Allegra again in April 2003 when seasonal allergic symptoms began again. Scalp itch flared up immediately, and I made the connection to Allegra. Has anyone else experienced or reported this side effect?
