Disadvantages:

1.The insulin pen itself needs more than 200 yuan to buy, but a special insulin refill needs to be used, and ordinary insulin cannot be used in the pen. There are only foreign-made insulin refills in China, and insulin refills are more expensive than ordinary insulin.

2. When considering the cost, patients should also consider that if they use an insulin pen, they will be exempted from the cost of buying plastic syringes for life.

3. When the patient needs to inject two kinds of insulin (such as Novolin R + Novolin N or Humulin R + Humulin N), the insulin pen cannot be completed at one time. At this time, it is best to have two pens to inject separately, which will cause inconvenience to the patient. In this case, premixed insulin novolin 30R or Humulin 30R refills are often used instead, which can be done in one go. Generally, one type of insulin uses an insulin pen. Therefore, when you want to use an insulin pen for diabetes, it is best to ask your doctor to adjust your insulin regimen to only one type of insulin, such as premixed insulin 30R or 50R, because premixed insulin contains both short-acting insulin R and intermediate-acting insulin N.

4. This kind of insulin pen and refill has not yet been popularized in our country, therefore, you may not be able to buy insulin refills in some areas, and you need to bring enough insulin refills when you go out for a long time. Cause inconvenience to patients.

Advantages:

1.It is convenient and eliminates the cumbersome process of using a syringe to draw insulin from an insulin bottle. Patients no longer need to bring a lot of items such as syringes, insulin bottles, and disinfectant cotton wool when they go out, but only need to bring a small "fountain pen".

2. The insulin injection process is simpler and more hidden, which can avoid the embarrassment of patients injecting insulin in public. Some people even took insulin injections with one hand right under the table, and the people at the table didn't know it.

3. It is convenient to inject insulin for patients with poor vision or even blindness. We know that it is not possible to use a syringe to draw insulin and inject it with poor vision. Because the insulin pen is easy to operate and the dose setting has a clear "click" sound, it can be injected with an insulin pen even if the vision is poor.

4. The insulin dose is more accurate, and the insulin dose can be adjusted in 1 unit. Syringes, on the other hand, are generally as small as 2 units.

5. It is basically painless, and the needle is thinner than the needle of the special insulin syringe, and some patients think that there is basically no pain after using it.
