What is Cetirizine and what are its uses ?

Cetirizine is an antihistamine. Antihistamines work by preventing the effects of a substance called histamine, which is produced by the body. 

Cetirizine is used to relieve or prevent the symptoms of hay fever and other types of allergy.

Cetirizine 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 apparent cause. Blocking the actions of histamine relieves the itching and reduces the rash associated with this condition.

How does Cetirizine Works (Mechanism) ?

Cetirizine is a type of medicine called a non-sedating antihistamine. Cetirizine works by preventing the actions of histamine.

Histamine is a substance produced by the body as part of its defense mechanisms. It is stored in cells called mast cells, in almost all tissues of the body. When the body reacts to a foreign substance (known as an allergen, e.g. flower pollen), the mast cells stimulated by the allergen release their stores of histamine.

Cetirizine works by blocking histamine H1 receptors. Cetirizine does not prevent the actual release of histamine from mast cells, but prevents it binding to its receptors. This in turn prevents the release of other allergy chemicals and increased blood supply to the area, and provides relief from the typical symptoms of hay fever. 

Dosage: How should you take Cetirizine ?

Take Cetirizine tablets orally.

Swallow the tablets with a drink of water. You can take Cetirizine with or without food.

Adults and Children 12 years and older
The usual starting dose of Cetirizine is 5 or 10 milligrams of Cetirizine once a day, depending on the severity of your symptoms. If you have a kidney or liver condition, the doctor will probably prescribe 5 milligrams daily.

The usual starting dose of Cetirizine is 5 or 10 milligrams once a day. If your child has a kidney or liver condition, the doctor will probably prescribe the lower dose.

Have you skipped your Cetirizine dose?
