Promethazine was developed in the mid-1940s when a team of scientists from the French chemical manufacturing company Rhône-Poulenc combined phenothiazine and a diamine side chain of diphenhydramine to create a new drug. Their creation, promethazine, is a synthetic medication that belongs to a pharmaceutical family known as phenothiazines. As a medication, promethazine has several uses, including treating allergies, motion sickness, and more. It is also a strong sedative that is sometimes prescribed during labor, before and after surgery, and at other times. Promethazine is a first generation antihistamine that is only available by prescription. It effectively treats several conditions, such as: As an antihistamine, promethazine competes with histamine for binding at some of its receptor sites (H1-receptors), thereby blocking histamine from binding to many. This, in turn, prevents or reduces the typical effects of histamine activating those receptors, including hives, constriction of the airways, nausea, increased wakefulness, nasal congestion, sneezing, and a runny nose.

Phenergan is a medication used to alleviate feelings of nausea, such as those experienced during travel sickness. It contains an agent called promethazine, which is a type of drug called a phenothiazine. This works in the body to reduce the effect of an inflammatory chemical called histamine, which is released by the immune system. The dose you use will usually depend on the type of nausea it is being used to treat. The feeling of sickness, or urge to be sick, is referred to in medical terms as nausea, and is often succeeded by actual sickness, or vomiting. There are a number of reasons why someone might experience nausea, and the treatment method for the condition may vary according to the cause. In the body, it is an area of the brain called the ‘vomiting centre’ which sends signals to the stomach and instigates the muscle spasms that cause sickness. The vomiting centre kicks into action when it receives confusing or irritating stimulus from other parts of the body.
