Injecting a dose of insulin with the insulin pen. Injection site rotation is important for both insulin syringe and pen users.
Same Time, Same General Location
Insulin is absorbed at different speeds depending on where you inject, so it's best to consistently use the same part of the body for each of your daily injections. For example, do not inject your lunch bolus dose in the abdomen on Monday and in the thigh on Tuesday. If you have picked the thigh for your evening injection, then continue to use the thigh for all of your evening injections.
