What is Phenergan (Promethazine)?

Phenergan is the name used for Promethazine, a first-generation antihistamine. In contrast to the newer antihistamines, which predominantly inhibit H1 receptors in order to lessen allergies, Promethazine has additional properties that make it effective as a sedative, an antiemetic (prevents vomiting or nausea), and, in certain cases, as an adjunct to analgesia.

The versatility of Phenergan means Phenergan may be used for a variety of reasons, such as:

• The treatment of allergic reactions, such as hay fever, hives, or rhinitis
• Eliminating and preventing nausea and vomiting, which includes those due to motion sickness or operations
• Serving as a sedative, or helping to sleep in certain circumstances
• Treating symptoms of vertigo and dizziness
• Helping with anesthesia in the form of a treatment before surgery

How Does Phenergan Work?

Phenergan operates by blocking histamine H1 receptors inside the body. Histamine is a substance released in allergic reactions, which results in symptoms like swelling, itching, and a runny nose. By blocking histamine, Phenergan decreases the allergic reaction symptoms.

Furthermore, Promethazine also provides significant antiemetic effects due to its blocking of dopamine receptors within the brain’s vomiting centre and helps to prevent vomiting and nausea. The effects of sedation are connected to its effect upon the receptors of the central nervous system, which cause drowsiness as well as calming.
