What are Cetirizine 10 mg Tablets?

Cetirizine 10 mg tablets are an antihistamine medicine used to treat seasonal allergies such as hay fever. They help relieve common allergy symptoms including sneezing, runny nose, itchy or watery eyes, and itching of the throat or nose.

How do Cetirizine Tablets work?

Cetirizine is a non-drowsy antihistamine. It works by blocking histamine, a chemical released in the body during an allergic reaction. This helps to reduce inflammation and ease symptoms without causing as much drowsiness as older antihistamines.

When to consider Cetirizine Tablets

During hay fever season to control symptoms triggered by pollen.
For allergy symptoms caused by pets, dust, or mould.
For relief of itchy rashes or hives (urticaria) linked to seasonal allergies.

Who can use Cetirizine Tablets

Adults and children over 6 years old.
People looking for once-daily relief from seasonal allergy symptoms.

Who should not use Cetirizine Tablets

Children under 6 years (tablets may not be suitable, but liquid forms are available).
People allergic to cetirizine, hydroxyzine, or any ingredients in the tablets.
Individuals with severe kidney disease should avoid or use with caution under medical advice.

How to take Cetirizine Tablets

The usual dose for adults and children over 12 years is one 10 mg tablet once daily.
Children aged 6–12 years may be advised half a tablet (5 mg) twice daily.
Swallow with water, with or without food.
Do not take more than the recommended dose.

Alternatives to Cetirizine

Other non-drowsy antihistamines such as loratadine or fexofenadine may be recommended. Nasal sprays and eye drops can also be used for targeted symptom relief.
