2. Multiple daily injections of short or fast acting insulin with one or two separate injections of intermediate or long acting insulin

This type of regimen is termed as 'intensive' or 'flexible' insulin therapy. Short or fast acting insulin is given before meals and long acting insulin is given at bedtime. Although a lunchtime injection is usually required, the use of a pen injector can make it a quick and easy task. This insulin regimen is much more flexible especially for mealtimes. It can easily accustom according to the body's natural needs, by providing constant supply.

This regimen work as follows:

the short or fast acting insulin takes care of meals
the long acting insulin takes care of background insulin needs
