Will insulin kill if injected into vein?

Insulin is a hormone that helps the body use sugar for energy. When injected into a vein, insulin can cause a person's blood sugar to drop suddenly. This can lead to a variety of symptoms, including confusion, dizziness, blurred vision, seizures, and coma. In severe cases, insulin can cause death.

The amount of insulin that is required to cause death varies from person to person. However, a dose of just a few units of insulin can be fatal if injected into a vein.

Insulin is not typically injected into a vein. It is usually given as a subcutaneous injection, which means that it is injected into the tissue beneath the skin. This allows the insulin to be absorbed slowly into the bloodstream, which helps to prevent a sudden drop in blood sugar.

If you are prescribed insulin, it is important to follow your doctor's instructions carefully. Never inject insulin into a vein. If you have any questions about how to use insulin, talk to your doctor.
