of confusion and a lack of coordination (often confused with drunkenness) can lead to a rapid loss of consciousness.
Death from histotoxic hypoxia requires sufficient insulin to drive blood sugar levels down long enough to ensure cerebral death. A dose on 1000IU of a rapid acting form of the drug will be lethal.
Significant Problems using Insulin
The biggest problem using insulin to end life is that it must be injected subcutaneously. There are no oral forms of the drug.* Preloaded insulin pens may hold 300IU and may be able to deliver 60IU per injection. But trying to deliver 1000IU (ie. using 3 pens, and 15 injection sites) is practically impossible. Note also that too large a dose delivered at one site can result in pooling and a restriction of blood flow to that area. This will reduce the drug’s effect.
Typical subcutaneous insulin injection using a delivery pen
* There is an available inhaled rapid acting insulin, but only 24IU can be delivered per inhallation
