Cetirizine was originally a prescription-only drug, but is now available without a prescription in many pharmacies around the world. Since its launch, Cetirizine has become one of the most popular antihistamines on the market, with millions of prescriptions every year. It is often considered more effective and has fewer side effects than first-generation antihistamines such as diphenhydramine. Over the years there has been research into the use of Cetirizine to treat other conditions such as asthma and eczema, but its effectiveness for these conditions is not yet clearly established. Despite this, Cetirizine remains one of the most popular drugs for the treatment of allergies and continues to be widely used throughout the world.

D- How does Cetirizine work?

Cetirizine is a second-generation antihistamine that works by blocking the action of histamine, a chemical produced by the immune system in response to an allergy. When you’re exposed to an allergen like dust or pollen, your body produces histamine, which leads to symptoms like sneezing, stuffy nose, and itching. Cetirizine binds to histamine receptors in the body, preventing histamine from attaching to these receptors and thus reducing the allergic response. Cetirizine is also known to have low affinity for other central nervous system receptors, which means it has few side effects such as drowsiness or confusion. Cetirizine usually starts working within an hour of taking it and can last up to 24 hours. It is important to note that Cetirizine does not cure allergies, but it can help relieve symptoms associated with allergies, which can improve the quality of life for allergy sufferers.
