Symptoms of overdose can be similar to the medication’s side effects but are usually more severe. The most common symptoms of insulin overdose is hypoglycemia (low blood glucose).

Consulting the physician is vital for pregnant women. Insulin needs change for women during and after pregnancy. Women must control glucose (blood sugar) during pregnancy to prevent excessive weight gain of the fetus (macrosomia) or high or low glucose in the baby.

Insulin does not pass into breast milk. However, nursing mothers generally need less insulin. Regular glucose testing can help to detect the need to change insulin dosages. When insulin is used during breastfeeding, the glucose levels in the mother and the baby should be monitored.
