USES OF PROMETHAZINE
Nausea is an uneasy or unsettled feeling in the stomach together with an urge to vomit. Nausea and vomiting, or throwing up, are not diseases. They can be symptoms of many different conditions.
Vomiting is the expulsion of the contents of stomach through the mouth and can be voluntary or involuntary.
Treatment of Allergic conditions
An allergy is the body’s way of responding to any foreign substance. The immune system produces an exaggerated response by releasing antibodies called immunoglobulin E (IgE) to the foreign substance. The foreign substance could be harmless or could cause minimal to a serious allergic response in the body.
Motion sickness is a feeling of dizziness with nausea and vomiting that occurs as a response to motion (travel). It is a common condition that makes traveling uncomfortable and unpleasant for many people.
It can occur as car sickness, train sickness, air sickness, or sea sickness. It can also occur in a motion simulator where there is no real motion.

HOW PROMETHAZINE WORKS
Promethazine is an antiallergic medication. When your body is exposed to an allergen (pollen, animal dander, house dust etc.), it produces a chemical called histamine. This causes watery eyes, runny or blocked nose, sneezing, skin rashes, itching etc. Promethazine works by blocking the action of histamine, thereby relieving these symptoms. It also works directly on several areas of the brain to prevent nausea/vomiting and help you feel more relaxed.
Promethazine may cause excessive drowsiness with alcohol.
