Medicinal Benefits

Phenergan Injection 2 ml contains Promethazine, an antihistamine (anti-allergic drug) 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 covering the eye) and other types of allergy. It blocks the action of histamine, a substance responsible for causing allergic reactions. Thereby, it helps to provide relief from symptoms of allergy. Also, it blocks the histamine receptors in the vomiting centre in the brain and prevents nausea and vomiting after surgery due to certain types of anaesthesia and motion sickness. Additionally, Promethazine possesses sedative effects and helps you feel relaxed before and after surgery. Thus, it is used in postoperative, preoperative and obstetric (during labour) sedation. Phenergan Injection 2 ml may be used to treat a symptom of Parkinson’s disease known as oculogyric crises (uncontrolled rolling of eyeballs).
