Diabetes practices and regimens can vary between countries, hospitals / clinics, & specialists.  Therefore what may be encouraged in one setting may not be so recommended in another.  This insulin tutorial is not meant to provide a didactic (regimented / fixed) plan for using insulin.  Rather the tutorial intends to show some ways of doing things, and provide some explanations as to why things may be done in a certain way.  Furthermore it is hoped that this tutorial may encourage people to think a bit more about what insulin regimens are possible, & how they might be improved and / or tailored for an individual.  In all this remember that people's mileage may vary - so what works for one person may not be appropriate for someone else.  Therefore, as with all medical information on the Web, it is important that you consult your doctor or diabetes specialist before considering acting on any of the information discussed in this tutorial.

2. Long-acting insulin

2. Long-acting insulin
has an effect which comes on more slowly than that of soluble insulin but lasts longer.

Although regular insulin has to be injected at least three times a day, long-acting insulin needs to be injected only twice or even once a day.

This is roughly what the activity curve of a long-acting insulin looks like.
Most long-acting insulins are nowadays manufactured by processes based on the

NPH delayed action principle.
They are called: NPH insulins.

Action characteristics:
Onset of action:
½ to 1½ hours.
Peak activity: 4 to 7 hours.
Duration of action: 14 to 18 hours after injection.

The greatest advantage of NPH insulins is that they can be mixed in the syringe with regular insulin. Nevertheless, NPH insulin should always be mixed with regular insulin from the same manufacturer.
