Cetirizine hydrochloride 10mg is a widely prescribed antihistamine medication used to treat various allergic conditions. It belongs to the second generation of antihistamines, which are known for their selective action on peripheral histamine receptors, minimizing the risk of drowsiness and other central nervous system effects.
What is Cetirizine Hydrochloride?
Cetirizine hydrochloride is a white, crystalline powder that is soluble in water and slightly soluble in ethanol. It is the active ingredient in many over-the-counter (OTC) and prescription allergy medications. The medication is available in various forms, including tablets, capsules, syrups, and solutions for oral administration.
How Does Cetirizine Hydrochloride Work?
Cetirizine hydrochloride works by blocking the action of histamine, a chemical released by the body during an allergic reaction. When histamine binds to its receptors on the surface of cells, it triggers a series of events that lead to the characteristic symptoms of allergies, such as itching, sneezing, runny nose, and congestion. By blocking the histamine receptors, cetirizine hydrochloride prevents these symptoms from occurring, providing relief to individuals suffering from allergies.
What Conditions is Cetirizine Hydrochloride Used to Treat?
Cetirizine hydrochloride 10mg is commonly used to treat a range of allergic conditions, including:
- Hay Fever (Allergic Rhinitis): Cetirizine hydrochloride helps to alleviate symptoms such as sneezing, runny nose, itchy eyes, and congestion associated with hay fever.

- Itchy Skin (Pruritus): Cetirizine hydrochloride can provide relief from itchy skin, which can be caused by a variety of conditions, including eczema, psoriasis, and dry skin.
- Insect Bites and Stings: The medication can help to reduce the itching, swelling, and redness associated with insect bites and stings.
