Interactions between narcan(naloxone) and Methadose (methadone)
methadone and naloxone (Major Drug-Drug)
MONITOR CLOSELY: This warning does not apply to the naloxone component in oral pentazocine/naloxone tablets. Naloxone injection is an antagonist that will reverse the actions of opiates. This reversal can occur when the opiate drug is being used clinically and when it is being abused. Physically dependent patients may experience withdrawal symptoms. Abrupt postoperative opioid reversal has resulted in hypotension, ventricular tachycardia and fibrillation, pulmonary edema, cardiac arrest, encephalopathy, and death.
MANAGEMENT: Patients receiving naloxone injection should be monitored for changes in vital signs, nausea, vomiting, diarrhea, aches, fever, runny nose, sneezing, nervousness, irritability, shivering, abdominal cramps.
