What should I do if I take too much Humulin?

If you take too much Humulin, a synthetic version of insulin, you may experience hypoglycemia, or low blood sugar. Insulin is an essential hormone that controls blood sugar.

If this happens, eat or drink something containing about 15 grams of carbohydrate, such as a half-cup of fruit juice, then check your blood sugar level. If it is still low, eat another 15 grams of carbohydrate and check your blood sugar again. If it is still low, or if you experience confusion, loss of consciousness, coma or seizures, you need immediate medical attention. Call emergency services or have someone take you to an emergency room.

Talk to your doctor about what to do if you take too much Humulin and experience hypoglycemia. Call your doctor immediately if you have any of the following symptoms and eating a high-carbohydrate snack doesn’t help:
  • hunger
  • shakiness
  • dizziness
  • headache
  • irritability
  • sweating
  • blurred vision
  • fast heartbeat
  • nervousness
  • difficulty sleeping
