Phenarzine 25mg/1ml Promethazine Injection - 1 Ampoule
Severe, life-threatening allergic reactions (anaphylaxis) or uncontrollable hospital vomiting require immediate, potent systemic suppression. Phenarzine 25mg Injection delivers rapid clinical control. Formulated with Promethazine Hydrochloride—a powerful first-generation phenothiazine antihistamine—it aggressively blocks histamine H1 receptors to reverse allergic swelling, while its central action profoundly calms the vomiting center in the brain and induces deep patient sedation prior to surgical procedures.
How to Use / Operate
For administration by trained healthcare providers only. Preferred route is deep Intramuscular (IM) injection. Intravenous (IV) administration must be done extremely slowly (diluted) due to the high risk of severe tissue damage and necrosis if extravasation occurs.
Frequently Asked Questions
What is Phenarzine 25mg Injection used for?
It is an emergency hospital injection used to treat severe allergic reactions, stop intractable vomiting, and provide deep sedation before or after surgery.
Why is it given by injection instead of pills?
Injectable delivery bypasses the digestive system, providing immediate, life-saving effects when a patient is unconscious, vomiting severely, or in anaphylactic shock.
Important Clinical Considerations
Strictly contraindicated in pediatric patients under 2 years of age due to the risk of fatal respiratory depression. Intra-arterial or subcutaneous injection is strictly prohibited, as it causes severe chemical irritation leading to gangrene and limb amputation. Monitor patient blood pressure closely.
