Drug-induced hypoglycemia

  • Definition
    • Drug-induced hypoglycemia is low blood sugar that results from medication.

  • Causes
    • Low blood sugar is common in people with diabetes who are taking insulin or other medicines to control their diabetes.

      All of the following can cause blood sugar (glucose) levels to drop:

      • Drinking alcohol
      • Getting too much activity
      • Intentionally or unintentionally overdosing on the medications used to treat diabetes
      • Missing meals

      Even when diabetes is managed very carefully, the medications used to treat diabetes can result in drug-induced hypoglycemia. The condition may also occur when someone without diabetes takes a medicine used to treat diabetes. In rare cases, non-diabetes-related medicines may cause hypoglycemia.

      Medications that can cause drug-induced hypoglycemia include:

      • Bactrim (an antibiotic)
      • Beta-blockers
      • Haloperidol
      • Insulin
      • MAO inhibitors
      • Metformin when used with sulfonylureas
      • Pentamidine
      • Quinidine
      • Quinine
      • SGLT2 inhibitors (such as dapagliflozin and empagliflozin)
      • Sulfonylureas
      • Thiazolidinediones (such as Actos and Avandia)
