What are the side effects of Humulin?

The chief side effect associated with the use of Humulin is low blood sugar, also called hypoglycemia. This occurs when your blood sugar drops too low, something that can happen if your insulin dose does not match the needs of the body. Diabetics who feel hypoglycemia beginning can correct it with a dose of sugar from hard candy or orange juice. Symptoms of hypoglycemia include: behaving strangely; moving unsteadily; trembling; feeling anxious, confused, nervous or depressed; feeling drowsy or fatigued; feeling hungry, nauseous or lightheaded; speaking with slurred words or experiencing blurry vision; cold sweats or sweating excessively; headaches; or a tingling feeling in the hands or face. Hypoglycemia can result in a coma. Symptoms of an allergic reaction to Humulin may include: body rash; shallow breathing or shortness of breath; wheezing; sweating; or fast heart rate and low blood pressure. This requires immediate medical attention.
