CETIRIZINE

CETIRIZINE: Cetirizine is an antihistamine drug that is commonly used to treat allergic conditions such as hay fever (allergic rhinitis), hives (urticaria), and itchy skin caused by hives. It is sold under various brand names, including Zyrtec.

The mechanism of action of cetirizine involves blocking the action of histamine, a chemical involved in the body’s allergic response. By inhibiting the histamine receptors, cetirizine prevents the symptoms associated with allergies, such as itching, sneezing, runny nose, and watery eyes.

The typical recommended dose of cetirizine for adults and children above the age of 12 years is 10 mg once daily. For children aged 6 to 11 years, a dose of 5 mg once daily is usually recommended. It is available in tablet, chewable tablet, and syrup forms. It is important to follow the instructions provided by the healthcare provider or as mentioned on the product label.

Common side effects of cetirizine include drowsiness, dizziness, dry mouth, sore throat, and headache. These side effects are usually mild and go away on their own. However, if these side effects persist or worsen, it is advisable to consult a healthcare professional.

In rare cases, cetirizine may cause more serious side effects such as difficulty breathing, rapid or irregular heartbeat, severe dizziness, and allergic reactions. If any of these severe side effects occur, immediate medical attention should be sought.

It is important to note that cetirizine may interact with other medications or medical conditions. It is always recommended to inform the healthcare provider about all current medications, medical history, and any other relevant information before starting cetirizine or any new medication.
