This medicine contains the active ingredient cetirizine, which belongs to a group of medicines called antihistamines. These medicines reduce the effects of histamine (a chemical produced in our body after the contact with pollen or other substances) by disabling histamine receptors to bind with histamine. If this binding is not disabled, we have symptoms such as itching, sneezing, wet eyes, runny nose. Cetirizine is used to help us ease these symptoms of allergies.
