Cetirizine: Uses, Side Effects & Brands in Pakistan

Cetirizine is a second-generation antihistamine used for allergies. It is available without a prescription in Pakistan as tablets, syrups and drops, and many people take it during spring pollen season or for dust allergy.

How Cetirizine works

During an allergic reaction the body releases histamine, which causes sneezing, itching and swelling. Cetirizine blocks histamine receptors, so symptoms ease. It causes less drowsiness than older antihistamines such as chlorpheniramine, although some people still feel sleepy.

What is Cetirizine used for?

  • Hay fever and seasonal allergies, including pollen allergy
  • Year-round allergic rhinitis from dust mites or pets
  • Itchy, watery eyes caused by allergy
  • Hives (urticaria) and allergic itching

Side effects of Cetirizine

Not everyone gets side effects. The ones reported more often are:

  • Drowsiness or tiredness
  • Dry mouth
  • Headache
  • Dizziness

Get medical help straight away if you notice signs of a serious allergic reaction, such as swelling of the face, lips or throat, difficulty breathing, or a widespread rash.

Precautions and warnings

  • If it makes you drowsy, do not drive or operate machinery.
  • Avoid alcohol, which can increase drowsiness.
  • People with kidney disease may need a lower dose.
  • Use the children’s syrup or drops for young children, following the pack or your doctor’s advice.
  • Ask a doctor before using it in pregnancy or while breastfeeding.

Frequently asked questions about Cetirizine

Does cetirizine make you sleepy?

It causes less sleepiness than older antihistamines, but some people still feel drowsy. Try it first when you do not need to drive, and many people find taking it in the evening helps.

What is the difference between cetirizine and levocetirizine?

Levocetirizine is the active half of the cetirizine molecule, so it is used at a lower strength. Both treat the same allergy symptoms.
