Phenergan Ampoules Contain an Antihistamine, Anti-Nausea, and Sedative Drug

Phenergan Ampoules come in a kit of 10 x 1ml of Promethazine and is preferably administered as an injection deep into a muscle but can be given into a vein. Your doctor or other skilled healthcare professional will perform the injection of Promethazine as part of the treatment for a severe allergic reaction, a pre-operative shot to relax you or to prevent nausea and vomiting and post-operatively to keep you at ease and to stop any nausea or vomiting or given with an analgesic to help any pain or swelling.

How Promethazine Works

As an antihistamine, Phenergan Ampoules blocks histamine from binding to its receptors in different areas in your body to stop the actions of histamine in order to treat anaphylaxis and other symptoms of allergies like a runny nose and watery eyes. Because Phenergan Ampoules can cross the blood-brain barrier, the normal action of the histamine in your brain is disrupted and levels drop, making you feel drowsy and can lead to sedation. To treat or prevent motion sickness, Phenergan Ampoules blocks histamine and muscarinic receptors in the vomit center of your brain in order to stop receiving messages from your vestibular system, including your eyes and middle ear that tell your brain you are moving.

What Does Histamine Do?

Histamines are produced by your immune system cells in reaction to an injury, or a perceived threat. When signaled, histamine rushes to the affected site and causes inflammation to contain the threat and dilates blood vessels to increase the flow of blood and capillaries become leaky to accommodate more permeability as other substances are alerted to this emergency. Your weepy eyes and runny nose is caused by histamine trying to wash out the intruder that is usually harmless but histamine is not taking any chances. Histamine is also very important for your sleep/wake cycle as histamine levels rise and fall.

Before You Are Administered Phenergan Ampoules

Tell your doctor if you are pregnant, trying to conceive, or are breast feeding before being administered Phenergan Ampoules. Explain other medical conditions and allergies you have to your doctor and list all OTC and Rx drugs, as well as any herbal remedies and vitamin supplements you currently take or use. This will help the doctor decide if Phenergan Ampoules are right for your situation.
