What Is Loratadine (Clarityn) 10 mg?

Loratadine 10 mg, sold under the brand name Clarityn in many countries, is a second-generation antihistamine used to relieve symptoms caused by allergies. It helps reduce the effects of histamine, a natural substance released by the body during an allergic reaction.

Loratadine is commonly used to treat:

• Hay fever (seasonal allergic rhinitis).
• Year-round allergies (perennial allergic rhinitis).
• Hives (urticaria).
• Itchy skin caused by allergic reactions.

• Dissolvable tablets (in some countries).

Many loratadine products are available over the counter, while others may be supplied on prescription depending on local regulations.

How Loratadine Works

Loratadine works by blocking histamine H1 receptors.

This action helps to:

• Reduce sneezing.
• Relieve a runny nose.
• Ease itchy or watery eyes.
• Reduce itching of the skin.
• Help control allergic hives.

Unlike many older antihistamines, loratadine has minimal effects on the brain, making it less likely to cause sedation.
