Promethazine is used in the treatment of nausea and vomiting. It is also used for short-term treatment of insomnia (difficulty sleeping) in adults and as a sedative in children aged 5 years and above.
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.
It also works directly on several areas of the brain to prevent nausea/vomiting and help you feel more relaxed.
