Levocetirizina Miril Dihydrochloride is a preparation of Levocetirizina Miril Dihydrochloride. Levocetirizina Miril is the active (levo) isomer of Cetirizine.

Levocetirizina Miril has a rapid and long-lasting action, allowing once-a-day administration.
Levocetirizina Miril is a second generation histamine H1 antagonist used to treat various allergic symptoms. It has a long duration of action as it is generally taken once daily, and a wide therapeutic window as animal studies show the maximal nonlethal dose is over 100x a normal dose.
