What happens if insulin given IV?
The main side effect of intravenous insulin is low blood sugar (hypoglycemia). Symptoms of hypoglycemia include: Shaking or feeling jittery. Sweating.
What route is insulin?
The most common route of insulin administration is subcutaneous insulin injections. There are many ways to deliver insulin subcutaneously such as vials and syringes, insulin pens, and insulin pumps.
