Phenergan Injection 2 ml belongs to the class of drugs called antihistamines used to prevent or treat symptoms of allergic conditions such as hay fever (seasonal allergies), allergic skin reactions such as itching or hives (itchy, raised bumps on the skin), allergic conjunctivitis (redness and irritation in the membrane that covers the eye) and other types of allergy. Also, it is used to prevent and treat nausea and vomiting after surgery due to certain types of anaesthesia and motion sickness. Additionally, Phenergan Injection 2 ml is used for postoperative, preoperative, and obstetric (during labour) sedation. An allergy occurs when foreign elements, known as allergens, attack and invade our body, thereby causing the release of histamine (a chemical messenger) that causes swelling, inflammation, redness, itchiness, and watery nose and eyes.

Phenergan Injection 2 ml contains Promethazine, an antihistamine (anti-allergic drug) that works by blocking the action of histamine, a substance responsible for causing allergic reactions. It helps relieve allergy symptoms such as sneezing, running nose, watery eyes, itching, swelling, and congestion or stiffness. Also, it blocks the histamine receptors in the vomiting centre in the brain and prevents nausea and vomiting. Additionally, Promethazine possesses sedative effects and helps you feel relaxed before and after surgery.
