Interactions

Drug: oral antidiabetic agents, ace inhibitors, disopyramide, fluoxetine, mao inhibitors, propoxyphene, salicylates, sulfonamide antibiotics, octreotide may enhance hypoglycemia; corticosteroids, niacin, danazol, diuretics, sympathomimetic agents, phenothiazines, thyroid hormones, estrogens, progestogens, isoniazid, somatropin my decrease hypoglycemic effects; beta-blockers, clonidine, lithium, alcohol may either potentiate or weaken effects of insulin; pentamidine may cause hypoglycemia followed by hyperglycemia. Herbal: Garlic, ginseng may potentiate hypoglycemic effects.

Nursing Implications

Assessment & Drug Effects

  • Monitor for S&S of hypoglycemia (see Appendix F). Initial hypoglycemic response begins within 15 min and peaks 45–90 min after injection.
  • Lab tests: Periodically monitor fasting blood glucose and HbA1C.
  • Withhold drug and notify physician if patient is hypokalemic.

Patient & Family Education

  • Do not inject into areas with redness, swelling, itching, or dimpling.
  • Ingest some form of sugar (e.g., orange juice, dissolved table sugar, honey) if symptoms of hypoglycemia develop, and seek medical assistance.
  • Check blood sugar as prescribed, especially postprandial values; notify physician of fasting blood glucose <80 and >120 mg/dL.
  • Notify the physician of any of the following: Fever, infection, trauma, diarrhea, nausea or vomiting. Dosage adjustment may be needed.
