Lorine FM is likely a brand name for a medication containing loratadine, which is a non-drowsy antihistamine used to treat allergy symptoms such as sneezing, runny nose, itchy or watery eyes, and hives. The 10mg dosage is a common strength for adults and children over 6 years of age. Loratadine works by blocking histamine receptors, which helps reduce allergic symptoms. It is generally well tolerated, but some people may experience mild side effects like headaches or dry mouth.
