Administer Phenergan 50 mg IM injection deep into a large muscle mass, such as the gluteus maximus or vastus lateralis. Avoid injecting into areas with prominent blood vessels or nerves. Always use aseptic technique to minimize the risk of infection.
Injection Site Selection and Preparation
- Inspect the chosen injection site for any lesions, inflammation, or bruising. Select a different site if abnormalities are present. Cleanse the injection site with an appropriate antiseptic solution (e. g., isopropyl alcohol 70%) using a circular motion, moving outward from the center. Allow the area to air dry completely before injection.
Use a 22-25 gauge needle for the injection. Aspirate before injecting to help ensure the needle is not in a blood vessel. If you aspirate blood, withdraw the needle and select a new injection site.
Injection Technique
With the needle bevel up, insert the needle at a 90-degree angle into the muscle. Slowly inject the medication. Once injection is complete, withdraw the needle at the same angle of insertion. Apply gentle pressure to the injection site with a sterile gauze pad. Do not massage the area.
Post-Injection Monitoring
Observe the patient for any immediate adverse reactions such as dizziness, lightheadedness, or hypotension. Monitor the injection site for swelling, redness, or pain. Report any significant reactions to the prescribing physician immediately.
Important Considerations
- This dosage and administration information is for guidance only; always refer to the most current prescribing information. Individual patient needs may vary; adjustments to the dosage may be necessary based on patient response and clinical judgment. Phenergan should be used with caution in patients with certain medical conditions, such as glaucoma, prostatic hypertrophy, or respiratory diseases. Discuss potential risks and benefits with the prescribing physician before administration.
Disposal
Dispose of used needles and syringes properly in a designated sharps container to prevent accidental needlestick injuries.
