Syringes vs. Pen Needles


Most diabetics are aware that there are two methods for administering insulin: syringes and pens. Unfortunately, there is no correct or incorrect answer as to which is superior. Insulin syringes and pen needles both have their benefits and drawbacks. "Which one will help you manage your diabetes the best?" is the question. Let's look at each option and the differences between using insulin pen needles and utilizing insulin syringes to answer that question.


Syringes for Insulin

The use of vials and syringes to inject insulin has been around for a long time and is still the method of choice for many people with Diabetes. However, one of the procedure's downsides is that it hasn't altered substantially over time. In addition, injecting with a syringe is more involved and necessitates the injector's undivided attention and care.

What is the procedure of injecting insulin utilizing a syringe?


  1. Fill the syringe with air until it reaches the exact number of units of insulin to get injected.
  2. Next, hold the insulin vial upright and put the needle through the rubber stopper directly. After that, push the syringe plunger down to let the air out of the vial.
  3. Turn the vial upside down and draw the specified amount of insulin and a tad extra into the syringe, making the needle remaining in the vial.
  4. Tap the syringe to remove surplus bubbles while retaining the needle within the vial. To get the correct dosage, carefully push out the surplus insulin.
  5. Take out the needle from the bottle and inject the insulin.


What are the advantages of using injecting insulin utilizing a syringe?


Insulin syringes require more attention and time, but the result is identical when done correctly, and the savings can mount up quickly. Another advantage of using vials and syringes over insulin pen needles is that you can mix several types of insulin in one injection.


If your diabetes treatment plan necessitates mixing several types of insulin, you've already made your option. The flexibility to create multiple syringes at once and keep them in the refrigerator is another advantage of utilizing needles.


Insulin pens and pen needles


Pens and pen needles for insulin are unquestionably handier and worry-free than traditional vials and syringes for administering insulin. There are two sorts of insulin pens- reusable and disposable. A cartridge in reusable insulin pens allows the user to dial up the correct dosage. When a cartridge runs out, it gets replaced. Disposable insulin pens that are pre-filled with a single dose are also available. The pen gets tossed once it has been used.


What is the procedure for preparing an insulin dose utilizing a pen?


  1. To mix the insulin, quickly but gently extend your forearm 20 times.
  2. Next, attach a new needle and prime the pen by gently pressing the injection button while holding it with the needle end pointed up until a small drop of insulin appears.
  3. You're now ready to inject the patient if you have a disposable pen.
  4. If you're using a reusable pen, adjust the dosage by twisting the dial before injecting.


What are the advantages of using pens and pen needles for insulin?


First, using a pen makes the operation simple and significantly less prone to human mistakes than using a vial and syringe. You can also take pens anyplace. Finally, they're far more accessible to transport than vials and syringes, so you may bring your diabetes supplies with you everywhere you go.


For many people with Diabetes, the expense of using pens is an issue. Unfortunately, you'll have to pay a premium for the increased convenience. Pen needles are also not included with the cells and acquired from a reputable diabetic healthcare vendor.


How should one select the correct needle?


After you've determined whether you need syringes or an insulin pen for your diabetes treatment, there's one more crucial step to make. What are the most effective and comfortable needle lengths and gauges for you?


Many people with Diabetes will claim that the needle size is the most crucial factor to consider when creating an insulin injection regimen. After all, the needle is the instrument that penetrates the skin and enters the fatty tissue. As a result, it can cause discomfort and, worse, it may not offer the necessary quantity of insulin absorption into the body if it isn't the right size for your body type and delivery needs.


Here are a few things to think about while choosing needle lengths and gauges.


According to a long-held belief, Longer is better for both insulin syringe needle sizes and pen needle sizes. Unfortunately, it is not the case when it comes to diabetic treatment. Insulin works best when injected into the layer of fatty tissue beneath the skin.


The longer needles can penetrate the muscular tissue and travel right through this layer. It not only causes more significant pain and bruising, but it also causes the insulin to get used up more quickly than most doctors would prefer, perhaps leading to hypoglycemia.


In reality, most people would benefit from a needle between 4mm and 8mm in length. In fact, according to research published by the American Diabetes Association, even patients who are overweight, who were previously thought to require longer needles, found that using a shorter needle made insulin injections more effective and safer.


Of course, it's always a good idea to talk to your doctor about your specific diabetes treatment plan, including needle length. Yes, that is right. Being in the medical industry for some time now, we suggest you consult your doctor to understand the pen needle sizes chart better and ask him what is best for you.


How to find the appropriate needle gauge?


The needle gauge is the measurement of a needle's thickness. For example, insulin syringe needles are usually between 28 and 31 gauge, while pen needles are generally between 31 and 32 gauge. So, the thinner the needle is, the higher the number.


So, how can you know which gauge is best for you?

The finer the needle gauge on an insulin syringe or a pen needle, the easier the needle will penetrate the skin and the less pain you'll feel. However, the correct needle gauge depends on your level of comfort as well as the amount of insulin you'll be administering.


A more significant, lower-gauge needle may help deliver the drug faster and more effectively if your treatment plan calls for a considerable dose of insulin. So while you may have some little discomfort as a result of the treatment, the efficacy of the treatment may be worth it.
