Insulin is usually injected using an insulin pen. The correct way to administer regular insulin needles: just choose the right injection site first, sterilize it, and inject it subcutaneously.
Insulin is the only hormone in the body that lowers blood sugar and is an effective means of treating diabetes. The injection site needs to be selected from areas rich in subcutaneous fat, which include: abdomen, outer thighs, outer upper arms, and outer and upper buttocks.
Insulin should be shaken well before injection, all air should be expelled before injection, the dose of insulin should be adjusted, then the skin should be sterilized and the needle should be inserted.
The injection should be made sure that it is done under the skin, and in the case of children and thin adults, the needle is inserted at an angle of 45 degrees to the skin. In the case of normal weight and obese adults, the needle can be injected at 90 degrees. Remove the needle after a 10-second dwell time.
In addition, the injection site should be changed frequently to avoid causing subcutaneous hardness or fat atrophy; insulin needles are disposable and should not be reused to avoid infection.
Insulin is a prescription drug and needs to be used under the guidance of a doctor. For more knowledge about insulin, please consult an endocrinologist.
