Motion sickness

• Individuals with history of motion sickness can present with increased nausea and vomiting sensations.
• Promethazine use helps with preventing and controlling the excessive nausea and vomiting sensations and offers relief from symptoms of motion sickness.

Nausea and vomiting of surgeries

• Anesthesia and surgical procedures can induce some nausea and vomiting, thus leading to complications such as aspiration.
• Promethazine use can reduce the nausea and vomiting associated with anesthesia and surgical procedures, thus reducing risk for aspiration.
• Promethazine use can reduce the nausea and vomiting during the post-surgical period, thus reducing the discomfort during the recovery phase.

Sedation and relaxation

• Promethazine use can help allay fear and anxiety before any medical and surgical procedures and promote sleep and relaxation, both before and after the procedure.
