Methadone HCl Injection 10 mg/mL – 20 mL Vial

Methadone HCl Injectable 10 mg/mL (20 mL vial, C-II) is a prescription opioid analgesic indicated for the management of moderate to severe pain. This injectable formulation provides rapid onset of analgesia and is commonly used in controlled clinical settings where effective pain control and sedation are required, including perioperative and acute care scenarios.

Methadone exerts its analgesic effects through opioid receptor activity and additional mechanisms that support sustained pain relief. Due to its potency and pharmacologic profile, careful dosing, administration, and continuous monitoring are essential to balance therapeutic benefit with potential risks such as respiratory depression, sedation, or altered responsiveness.

Use should follow established prescribing guidelines and institutional protocols, particularly when administered in combination with other central nervous system depressants. Methadone is classified as a Schedule II controlled substance and requires appropriate handling, storage, and documentation in accordance with regulatory requirements. Refer to manufacturer-provided labeling for complete information regarding indications, administration, precautions, and safety considerations.
