Clarityn Allergy tablets are rapidly absorbed and can relieve allergy symptoms such as sneezing, runny nose and itchy, burning eyes, whether these are due to hayfever or whether they occur all year round.

Clarityn Allergy tablets may also be taken for allergic skin conditions such as rash, itching or urticaria (hives).

Clarityn allergy tablets contain the active ingredient loratadine, which is a type of medicine called a non-sedating antihistamine.

Loratadine works by blocking histamine H1 receptors. It does not prevent the actual release of histamine from mast cells, but prevents it binding to its receptors.

Loratadine can also be used to relieve the symptoms of a condition called chronic idiopathic urticaria. This is a chronic itchy rash, similar to nettle rash, but with no apparant cause. Blocking the actions of histamine relieves the itching and reduces the rash associated with this condition.
