NPH Insulin

When and How to Take NPH Insulin

General considerations for taking NPH insulin include the following:
  • This diabetes medication comes in injectable form. It is injected just under the skin (subcutaneously), usually once or twice a day. There are many different strategies for dosing NPH insulin and other insulins; be sure to follow your healthcare provider's recommendations.
  • Your healthcare provider should show you exactly how to inject NPH insulin. It can be injected into the skin and fat layer of the abdomen (stomach), upper arm, or thigh.
  • NPH insulin comes in vials and prefilled disposable pen devices.
  • Because NPH insulin is a suspension, you must shake or roll the vial (or invert the injection device several times) until the insulin looks uniformly cloudy.
  • For this diabetes drug to work properly, it must be taken as directed. Make sure to monitor your blood sugar levels as your healthcare provider recommends. Even though NPH insulin is available without a prescription, it should not be used without a healthcare provider's approval and supervision.

Dosing Information

The dose of NPH insulin that your healthcare provider recommends will vary, depending on a number of factors, including:
  • The carbohydrate content of your meals
  • How you respond to NPH insulin (especially as measured by your blood sugar levels)
  • Your current dose of other insulins
  • Other medications you are taking
  • Other medical conditions you may have.
As with any medication, do not adjust your NPH insulin dose unless your healthcare provider specifically instructs you to do so.
