Implications for Patient Care
- Prochlorperazine is a phenothiazine antiemetic used to control nausea and vomiting produced by a variety of causes.[2,3,4]
- During this shortage use alternative anti-emetics. Oral and rectal prochlorperazine products are effective, however these routes may not be practical for all patients.[3,4]
- Injectable promethazine is a possible alternative to prochlorperazine for the prevention and treatment of nausea and vomiting (Tables 1 and 2 provides a summary of additional potential alternatives).[4,5] However, severe tissue injury in the event of perivascular extravasation, intraneuronal or perineuronal infiltration, or inadvertent intra-arterial administration is possible with promethazine.[2,3,6] The Institute for Safe Medication Practices provides guidance on preventing tissue injury with intravenous promethazine.
- The labeled route of administration for promethazine injection is deep intramuscular injection. Subcutaneous administration is contraindicated.[2,3]
- Limit the concentration used in the organization to 25 mg/mL and further dilute promethazine with 10 to 20 mL normal saline when administering intravenously. This allows for slower administration, reduces vesicant effects, and allows for extravasation to be detected more quickly.
- Limit the starting dose of intravenous promethazine to 6.25 mg to 12.5 mg intravenous. Promethazine 6.25 mg intravenous was as effective as 12.5 mg intravenous for controlling postoperative nausea and vomiting in a clinical study.
- Administer intravenous promethazine slowly over 10 to 15 minutes through a large bore vein (ie, central venous access is preferred; avoid the hand or wrist) via a running intravenous line at the furthest port from patient's vein.
- Instruct patients to immediately report signs of pain or burning.[2,3,6]
- Create alerts to remind healthcare workers of the risks associated with intravenous promethazine use.
Alternative Agents & Management
- No single agent can be substituted for prochlorperazine injection. The choice of alternative agents must be patient-specific and based on the clinical situation as well as the potential for adverse effects.[4,5]
- Consensus guidelines offer evidence-based recommendations for the pharmacologic management of postoperative nausea and vomiting. Tables 1 and 2 incorporate these recommendations for select injectable antiemetics.
