Loratadine is a long-acting antihistamine that relieves allergy symptoms. It rarely makes people sleepy, so many people prefer it for daytime use.
What Is Loratadine Used For?
- Hay fever (allergic rhinitis)
- Sneezing, runny nose, and itchy, watery eyes
- Hives and itching from allergies
How Does Loratadine Work?
Loratadine blocks histamine at the H1 receptors. This stops the sneezing, itching, and watery eyes that an allergy causes. One dose lasts about 24 hours.
