Why is this medication prescribed?

Clemastine is an antihistamine medication that is commonly prescribed for the treatment of allergy symptoms. It is used to relieve symptoms associated with various allergic conditions, including:

• Allergic Rhinitis: Clemastine is often prescribed to alleviate symptoms such as sneezing, runny or itchy nose, and itchy or watery eyes caused by seasonal allergies or other environmental allergens.
• Urticaria (Hives): Clemastine may be used to relieve the symptoms of hives, which include red, raised, and itchy welts on the skin.

Clemastine works by blocking the effects of histamine, a substance in the body that contributes to allergic symptoms.
