Allegra 120mg tablets are a medication used primarily for treating symptoms associated with allergic rhinitis (hay fever) and chronic idiopathic urticaria (hives of unknown cause). Here's a detailed description of Allegra 120mg tablets:

They are also used for the treatment of symptoms associated with chronic idiopathic urticaria (hives), including itching and rash.
