Zyrtec (cetirizine) is a medication used to treat allergies, such as hay fever, hives, and other allergic skin conditions. It belongs to a class of drugs known as second-generation antihistamines, which work by blocking the effects of histamine, a substance produced by the body in response to allergens.
Zyrtec is typically taken orally in tablet, liquid, or chewable form. The dosage and duration of treatment will depend on the specific medical condition being treated and the patient's age and weight.
Side effects of Zyrtec may include drowsiness, dry mouth, and headache. Rare but serious side effects may include seizures or an allergic reaction.
Zyrtec may interact with other medications, so it's important to inform your healthcare provider of any other medications you are taking before starting treatment with Zyrtec. It should also be used with caution in patients with certain medical conditions, such as liver or kidney disease.
