Metacin 120 Tablet

Overview

As a patient, it's essential to understand your medication to ensure safe and effective use. Metacin 120 Tablet, manufactured by Zydus Cadila, is a prescription medication containing the active ingredient Fexofenadine (120mg). This patient education guide will provide you with comprehensive information about Metacin 120 Tablet, including its uses, mechanism of action, dosage, side effects, warnings, and potential interactions.

Uses and Indications

Metacin 120 Tablet is primarily used to relieve symptoms associated with allergies, such as runny nose, sneezing, itchy or watery eyes, and hives. It is also used to treat pain and discomfort caused by various conditions. Additionally, it can be used for general health and wellness, particularly in individuals who experience frequent allergic reactions. The medication works by blocking the action of histamine, a substance in the body that causes allergic symptoms.

Mechanism of Action

Fexofenadine, the active ingredient in Metacin 120 Tablet, is a selective histamine H1-receptor antagonist. It works by binding to histamine receptors in the body, which prevents histamine from exerting its effects. As a result, the medication reduces the symptoms of allergies, such as itching, redness, and swelling. Fexofenadine does not readily cross the blood-brain barrier, which means it is less likely to cause drowsiness compared to other antihistamines.
