CETIRIZINE

Overview

Cetirizine is a commonly used allergy medicine that helps ease symptoms like sneezing, runny nose, itchy eyes, and skin rashes. It’s often used to treat both seasonal allergies (like pollen) and everyday allergies (like dust, pet hair, or mold).
Classification
Antihistamine
Uses
Sneezing and runny nose from seasonal triggers like pollen

Red, itchy, or watery eyes

Itching in the nose or throat

Skin rashes like hives that are itchy or swollen

Discomfort from indoor allergies such as dust mites, pet fur, or mold

It works by calming the body’s overreaction to allergy triggers, making you feel more at ease.
How It Works:
Cetirizine works by blocking the action of a chemical called histamine in your body. Histamine is released when you’re exposed to things you’re allergic to—like pollen, dust, or pet dander—and it causes symptoms like sneezing, itching, and watery eyes.
By stopping histamine from doing its job, cetirizine helps reduce these allergy symptoms and makes you feel more comfortable. It starts working fairly quickly and usually doesn’t make you very sleepy, which is why many people prefer it for daytime use.
Dosage:
As prescribed by your doctor.
Side Effects:
Most people tolerate Cetirizine well, but some may notice mild side effects like:
Drowsiness or feeling a bit sleepy (less than older allergy meds, but still possible)

Dry mouth

Headache

Feeling tired or low energy

Dizziness

Stomach discomfort or nausea (less common)

These side effects are usually mild and go away on their own
Precautions:
May cause slight drowsiness: While cetirizine is usually non-drowsy, some people might still feel a bit sleepy—so be cautious when driving or doing anything that needs focus until you know how it affects you.

Avoid alcohol: Drinking alcohol can make you more sleepy or dizzy when combined with cetirizine.

Talk to your doctor if pregnant or breastfeeding: Cetirizine is generally safe, but always check with your doctor before using it if you’re expecting or nursing.

Let your doctor know about other medications: Cetirizine can interact mildly with some medicines, so it’s best to share a full list with your healthcare provider.

Kidney problems: If you have kidney issues, your dose may need to be adjusted. Always use it under medical supervision in such cases.
