Cetirizine

Cetirizine is an antihistamine medication used to relieve symptoms associated with allergies and hay fever. It works by blocking the effects of histamine, a substance released by the body during an allergic reaction. This helps to reduce symptoms such as sneezing, itching, and runny nose. Cetirizine is available in both oral tablet and liquid forms, and is typically taken once daily. It is important to follow the dosage instructions provided by a healthcare professional, as taking more than the recommended amount may cause side effects such as drowsiness, dry mouth, and headache.
