What is it used for?
Cetirizine is an antihistamine used to relieve allergy symptoms such as sneezing, runny or blocked nose, itchy or watery eyes, and itching or hives on the skin.
How does it work?
It blocks the action of histamine, a chemical involved in allergic reactions. This helps reduce itching, sneezing, watery eyes and other allergy symptoms.
How to take/use it
Take it by mouth exactly as directed on the package or by a doctor. It may be taken with or without food. Do not take more than recommended.
Common side effects
Sleepiness or drowsiness, tiredness, headache, dry mouth, nausea or dizziness may occur.
Precautions
Cetirizine may cause drowsiness in some people; avoid driving or operating machinery until its effects are known. Avoid alcohol, as it may increase drowsiness. Seek medical advice if there is kidney disease, pregnancy or breastfeeding, or an allergy to cetirizine or similar medicines.
