Demerol (Meperidine HCL) 100mg/ml injection, also known by its generic name Meperidine Hydrochloride, is a medication used to manage pain in clinical settings. It is commonly employed in hospitals, surgical centers, and obstetric units to provide analgesia during procedures or for the treatment of acute pain.

What is Demerol Injection?

Demerol injection is a sterile solution containing Meperidine Hydrochloride, a synthetic opioid analgesic. It is administered via intramuscular or intravenous routes to rapidly alleviate pain. Demerol injection provides potent analgesia and sedation, making it suitable for use in various medical procedures.

Mechanism of Action

The mechanism of action of Demerol injection involves its interaction with mu-opioid receptors in the central nervous system. By binding to these receptors, Meperidine Hydrochloride inhibits the transmission of pain signals, modulates pain perception, and induces feelings of euphoria and sedation.

Medical Uses

Demerol injection is indicated for the treatment of acute pain, such as that occurring after surgery, trauma, or medical procedures. It is also used in obstetrics for pain relief during labor and delivery. Demerol injection provides rapid onset of analgesia, making it an effective option for managing acute pain episodes.

Dosage and Administration

The dosage of Demerol injection should be individualized based on the patient’s pain severity, medical history, and opioid tolerance. It is typically administered by healthcare professionals in controlled settings, with the dosage and frequency adjusted according to the patient’s response and tolerance.

Side Effects

Common side effects of Demerol injection include drowsiness, dizziness, constipation, nausea, vomiting, and respiratory depression. These side effects are dose-dependent and may vary in severity among individuals. Serious adverse reactions such as respiratory arrest or circulatory collapse are rare but may occur with high doses or prolonged use.

Precautions and Warnings

Patients receiving Demerol injection should be monitored closely for signs of respiratory depression, especially those with pre-existing respiratory conditions or elderly patients. Demerol injection should be used with caution in patients with a history of substance abuse, renal or hepatic impairment, or head injuries.


Demerol injection may interact with other medications, including other opioids, benzodiazepines, sedatives, and monoamine oxidase inhibitors (MAOIs). These interactions can potentiate the effects of Demerol or increase the risk of adverse reactions. Patients should inform their healthcare provider about all medications they are taking to avoid potential interactions.

Overdose and Treatment

An overdose of Demerol injection can be life-threatening and may manifest as respiratory depression, extreme sedation, coma, or death. In case of overdose, immediate medical attention is required. Treatment may involve the administration of opioid antagonists, supportive care, and monitoring in a healthcare facility.


There are several alternative options available for pain management, including other opioid and non-opioid analgesics, regional anesthesia techniques, and non-pharmacological interventions. Patients should discuss their pain management goals and preferences with their healthcare provider to determine the most appropriate treatment plan.


In conclusion, Demerol (Meperidine HCL) 100mg/ml injection is a valuable medication for the management of moderate to severe pain in clinical settings. With its potent analgesic properties and rapid onset of action, Demerol injection provides effective pain relief for patients undergoing medical procedures or experiencing acute pain episodes. However, it should be used cautiously and under the supervision of a healthcare professional to minimize risks.
