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 in 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.

Allergy: It occurs when foreign elements/allergens attack and invade our body, thereby causing the release of histamines. This chemical messenger 'histamine' causes swelling, inflammation, redness, itchiness, itchy/watery nose and throat, and watery eyes. Allergies generally occur due to chemicals, air pollution, pet danders, dust, pollen hairs, seasonal allergies like hay fever etc.

Nausea and vomiting: Nausea is a feeling of uneasiness in the stomach that often comes before vomiting. On the other hand, vomiting is the forcible voluntary or involuntary emptying of stomach contents through the mouth. In short, nausea and vomiting are not diseases but are symptoms of many conditions like infections, motion sickness, an early stage of pregnancy, and gastroparesis (slow stomach emptying). A receptor located in the brain known as the chemoreceptor trigger zone (CTZ) controls vomiting.
