This procedure involves injecting Promethazine HCl, a medication commonly used to treat nausea, vomiting, and allergic reactions. The injection is administered into a muscle or vein and provides relief by acting on the brain and other parts of the body.

Purpose

Promethazine HCl injection is used to manage several conditions, including severe nausea and vomiting, motion sickness, and allergic reactions. It can also be administered as a sedative or to enhance the effects of painkillers. The goal is to provide quick and effective symptom relief.

Indications

• Severe nausea and vomiting unresponsive to oral medication
• Preoperative, postoperative, or obstetric sedation
• Motion sickness
• Allergic reactions (e.g., hives, itching)

Preparation

• Patients may be advised to avoid eating or drinking for a few hours before the injection.
• Inform the healthcare provider about all medications and supplements being taken.
• Diagnostic tests may include a review of the patient's medical history and current medication regimen.

Procedure Description
