Medicine Description cetirizine 1%
cetirizine 1% oral drops is a medication that functions primarily as a selective antagonist of peripheral H1 histamine receptors. By blocking the action of histamine, a chemical released during allergic reactions, cetirizine reduces symptoms associated with allergies. It alleviates common symptoms such as sneezing, itching, and nasal congestion. Cetirizine's low penetration into the central nervous system minimizes sedation compared to other antihistamines, making it suitable for daytime use. Its long half-life allows for prolonged relief from allergic symptoms, providing patients with effective management of their conditions.
