Generic Cetirizine and its Uses
Generic Cetirizine is a non-sedating anti-histamine.
Generic Cetirizine treats both indoor and outdoor allergy symptoms, as well as chronic hives. In fact, no other allergy medicine of its kind is approved to treat more allergies than Cetirizine. And studies show that 1 dose of Cetirizine works for a full 24 hours.
Generic Cetirizine is the first antihistamine approved to treat indoor allergies in infants 6 months and up.
Generic 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.
Generic Cetirizine is called a non-sedating antihistamine as it does not enter the brain, and is therefore unlikely to cause drowsiness. However, some people may experience some slight sleepiness.
Working Mechanism of Generic Cetirizine
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.
The released histamine then binds to its receptors (H1 receptors), causing a chain reaction that results in allergic symptoms. It causes an increase in blood flow to the area of the allergy, and the release of other chemicals that add to the allergic response.
All this results in the symptoms of an allergic reaction. In hay fever, histamine causes inflammation of the nose, eyes, skin or airways and results in itchy watery eyes, a runny nose, sneezing and nasal congestion.
Generic Cetirizine 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. 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.
