Loratadine is a non-drowsy antihistamine used to relieve allergy symptoms affecting the nose, eyes, and skin.
It is commonly used for:
• Allergic rhinitis (hay fever): Relieves sneezing, a runny or blocked nose, and itchy, watery eyes caused by seasonal or year-round allergens.
• Chronic urticaria (hives): Reduces skin itching, redness, and raised welts caused by allergic reactions.
• Allergic conjunctivitis: Eases itching and watering of the eyes caused by allergens.
• Pruritus (itching): Provides relief from generalised itching related to allergic conditions.

Loratadine works by blocking histamine, a chemical the body releases during an allergic reaction.
When the body encounters an allergen such as pollen or dust, immune cells release histamine, which binds to receptors in the nose, eyes, and skin, triggering symptoms such as sneezing, itching, and swelling.
By blocking these H1 histamine receptors, loratadine prevents or reduces the severity of allergy symptoms. As a second-generation antihistamine, it is less likely to cross into the brain, which is why it causes less drowsiness than older antihistamines.
