Claritin (loratadine) (loratadine) — Uses, Dosage, Side Effects & Safety

Drug class: Second-generation antihistamine (H1 receptor antagonist)

Overview

Claritin (loratadine) is a non-drowsy antihistamine used to relieve symptoms of seasonal allergies (hay fever) and other allergic conditions, such as sneezing, runny nose, itchy or watery eyes, and itching of the throat or nose. It is also effective in treating symptoms of chronic urticaria (hives), including itching and rash. Loratadine works by blocking the action of histamine, a substance in the body that causes allergic symptoms. Because it is a second-generation antihistamine, it is less likely to cause drowsiness compared to older antihistamines. Key points: Claritin is available over-the-counter in many countries, is generally well-tolerated, and can be used by adults and children (age restrictions apply). Always follow dosing instructions and consult your healthcare provider if you have liver or kidney problems, or if you are pregnant or breastfeeding.
