Novolin R can be mixed with NPH insulin right before use. When you are mixing Novolin R insulin with NPH insulin, always draw the Novolin R (clear) insulin into the syringe first. Add together the doses (total number of units) of NPH and Novolin R that you need to inject.

Of course, it is not illegal to have a channel if you are younger, but you may want to try and figure that out first! Hope this helps!
