What is Loratadine?
Loratadine is a second-generation antihistamine used to relieve symptoms caused by allergies. It works by blocking histamine, a natural substance in the body responsible for allergy symptoms.
It is commonly used to treat seasonal allergies, hay fever, and skin-related allergic reactions without causing significant drowsiness.
How Loratadine Works
Loratadine works by blocking histamine receptors (H1 receptors) in the body. This helps reduce allergy symptoms such as:
- Sneezing
- Runny nose
- Itchy or watery eyes
- Skin rashes or hives
Because it does not easily enter the brain, it is known as a non-drowsy antihistamine for most users.
