Check with your doctor or diabetes educator and test several brands before you buy. Your equipment should suit your needs. Using a syringe that more closely matches your dose may help you more accurately draw up your insulin. If you are changing the syringe you use, check dosage lines carefully. In some syringes, one line is equal to one unit of insulin, but in others, each line is equal to two units of insulin.
Some syringes now have shorter needles which many people find to be more comfortable.
However, the depth of the injection can change the rate of absorption. Ask your doctor or diabetes educator to assess whether this would be a good alternative to your current syringe. Cost is another factor because many stores use insulin syringes as key sale items. You may be interested in reusing your syringes. While this practice remains controversial, many patients reuse syringes without any problems.
