Hypoglycemia is rare in patients without diabetes mellitus. Methadone is a synthetic μ-opioid receptor agonist used for cancer or non-cancer pain and the treatment of opioid dependence. Here, we report a case of a 31-year-old man who presented with recurrent hypoglycemic events that resolved on discontinuation of methadone. Thus, if hypoglycemia occurs while a patient takes methadone, the amount should be reduced or replaced with another opioid before a full investigation for inappropriate hyperinsulinism is initiated.

Methadone is used as an agent for chronic pain and management of opioid use disorder. While similar pharmacologically to other opioids, methadone does have unique characteristics, including long half-life, low cost, and high oral bioavailability. While advantageous in some ways, methadone is associated with unique adverse effects not seen with other opioids (ie, hypoglycemia).

Methadone use for opioid use disorder and chronic pain has increased since the start of the century with about 4.4 million dispensed prescriptions in 2009. With increased use of methadone, there has been increasing reporting of less commonly reported side effects (ie, hypoglycaemia).

Background: Methadone is a synthetic μ-opioid receptor agonist that is used in the management of pain, neonatal abstinence withdrawal syndrome, and opioid dependence. Overdose can cause miosis, respiratory depression, and central nervous system depression. Rarely, hypoglycemia has been reported.

To determine if recent observations of hypoglycemia in patients receiving high-dose methadone extended to an animal model, we explored the effects of methadone and other mu-opioids on blood glucose levels in mice. Methadone lowered blood glucose in a dose-dependent manner with 20 mg/kg yielding a nadir in average glucose levels to 55 ± 6 mg/dL from a baseline of 172 ± 7 mg/dL, an effect that was antagonized by naloxone and mu selective antagonists β-funaltrexamine and naloxonazine. The effect was stereoselective and limited to only the l-isomer, while the d-isomer was ineffective.
