FDA Requires Updates to Labeling for Promethazine Hydrochloride Injection Products

December 27, 2023 -- FDA is alerting health care professionals of labeling updates intended to further reduce the risk of severe chemical irritation and damage to tissues from intravenous administration of promethazine hydrochloride injection.

Promethazine hydrochloride injection is indicated to help manage certain allergic reactions, motion sickness, post-operative nausea and vomiting, and as a sedative or adjunct to analgesics.

FDA recommends health care professionals administer promethazine hydrochloride injection by deep intramuscular administration instead of intravenous administration. If promethazine hydrochloride injection must be administered intravenously, health care professionals should review and follow the updated information in the labeling to dilute promethazine hydrochloride injection and administer by intravenous infusion to reduce the risk of severe tissue injury.

FDA has required that manufacturers update their prescribing information for promethazine hydrochloride injection to include new safety information and update the carton labeling and container labels with the corresponding information.

If intramuscular injection is not possible, promethazine hydrochloride injection:

  • Can be administered intravenously only after dilution, as recommended, and infused through an intravenous catheter inserted in a large vein and preferably through a central venous catheter. Do not administer using intravenous catheters placed into veins in the hand or wrist.
  • Should not be mixed with other drugs or diluted with solutions other than 0.9% sodium chloride injection.
  • Is contraindicated for intravenous injection at concentrations greater than 1 mg/mL.

When diluting and administering promethazine hydrochloride injection by intravenous infusion, infuse over 20 to 40 minutes and follow the below preparation and infusion instructions in adult and pediatric patients (see the first and second tables below, respectively):

Promethazine Hydrochloride Injection

FDA notified healthcare professionals that a Boxed Warning is being added to the prescribing information for Promethazine Hydrochloride products, describing the risks of severe tissue injury, including gangrene, requiring amputation following intravenous administration of promethazine. The Boxed Warning will remind practitioners that due to the risks of intravenous injection, the preferred route of administration is deep intramuscular injection and that subcutaneous injection is contraindicated.

Perivascular extravasation, unintentional intra-arterial injection and intraneuronal or perineuronal infiltration of the drug may result in irritation and tissue damage. Healthcare professionals should be alert for signs and symptoms of potential tissue injury including burning or pain at the site of injection, phlebitis, swelling, and blistering.
