A specific overdose for insulin cannot be defined, however, hypoglycemia may develop over sequential stages if too high doses relative to the patient's requirements are administered.
Mild hypoglycemic episodes can be treated by oral administration of glucose or sugary products. It is therefore recommended that the diabetic patient always carry sugar-containing products.
Severe hypoglycemic episodes, where the patient has become unconscious, can be treated by glucagon (0.5-1 mg) given IM or SC by a trained person or glucose given IV by a healthcare professional. Glucose must also be given IV if the patient does not respond to glucagon within 10-15 min. Upon regaining consciousness administration of oral carbohydrate is recommended for the patient in order to prevent relapse.
