The best time to take ordinary Insulin is 30 minute before food, in that way the level of Insulin and sugar in blood after food match well. But in case you have eaten already, it is better to take the injection immediately after rather than not taking. There is a new but costly Insulin available (Aspart, Lispro), which can be injected immediately before food, i.e., you do not need a gap as it works faster than ordinary Insulin.
Where should I take injection?
You can take Insulin in outer sides of arms and thighs or in the tummy. Injection in the tummy probably is the best one as the area is big, injections are less painful and you can see very easily where you are injecting. The needle we use is very small and it can never go inside the tummy, the injection will always be in the front wall. Many people are worried that they will inject in the intestine or big blood pipes inside!
How can I go to doctor or nurse for injection everyday?
You shouldn"t, you need to inject yourself. It is our duty to teach you how to inject Insulin. There is always a fear initially, but everybody manages well once they learn. Insulin injection is less painful when you inject yourself rather than a doctor or nurse injecting.
