Phenergan tablets have sedative properties, which can be used to help with management of the symptoms of measles and chicken pox; also for short-term sedation. Histamine is a chemical released from mast cells, (cells involved in allergies) as part of the body’s defence mechanism during an allergic reaction and binds to H1 receptors in small blood vessels causing them to leak, allowing white blood cells and blood proteins into the tissues. These infiltrating cells produce inflammatory chemicals (prostaglandins and leukotrienes) that cause tissue swelling and irritation, which are symptoms of an allergic reaction. Promethazine in Phenergan is an H1 receptor antagonist and works by binding to histamine receptors and blocking the action of histamine without blocking its secretion. This action blocks histamine-mediated allergic reactions, relieving symptoms in the upper respiratory tract like nasal congestion, runny itchy nose and sneezing, and in the skin like redness, swelling and itching.
