Introduction to Cetirizine

Cetirizine is a widely used antihistamine medication. It is primarily prescribed for managing symptoms of allergies such as sneezing, runny nose, itching, and watery eyes. As a second-generation antihistamine, cetirizine offers effective relief with fewer sedative effects compared to its predecessors.

Understanding Allergies and Histamines

Allergies occur when the immune system reacts to foreign substances. These substances, known as allergens, cause the body to produce histamines, resulting in allergic symptoms. Common allergens include pollen, dust mites, and animal dander.

• Histamines: Chemicals produced by the immune system to help the body get rid of allergens. They cause blood vessels to expand and the skin to swell (hives).
• Allergic Response: Can include symptoms such as sneezing, itching, and swelling.

The Role of Cetirizine in Allergy Management

Cetirizine works by blocking the action of histamines in the body. This action helps alleviate the uncomfortable symptoms associated with allergic reactions.

• Efficacy: Known for its long-lasting effects that can provide relief for up to 24 hours.
• Safety Profile: Its non-sedating nature makes it a preferred choice for daily allergy control.
