IGKAST-L is a medication that contains Levocetirizine as its active ingredient. It is an antihistamine that is used to relieve symptoms of allergies such as sneezing, runny nose, itching, and watery eyes. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms.

IGKAST-L is commonly prescribed for the treatment of allergic rhinitis, which is inflammation of the nasal passages due to an allergic reaction. It can also be used to treat chronic idiopathic urticaria, which is a skin condition characterized by itchy, red, and raised areas on the skin. The medication is available in tablet form and is usually taken once daily.
