GlucoRx FinePoint Ultra 4mm 32G pen needles are single-use needles for insulin pens, supplied in a box of 100. GlucoRx states that they fit all insulin pen devices, and that the 4mm Ultra needle has a 5-bevel tip, which it says gives a higher level of comfortable injection than a 3-bevel needle.

Key Features

• 4mm length: GlucoRx states that short needles are reported to give low-pain injections, and that 4mm needles are mostly used in children and 4mm, 5mm or 6mm needles in adults, depending on the injection site.
• 32G needle with a 5-bevel tip: The 4mm Ultra is one of the sizes in the FinePoint range that has a 5-bevel tip instead of a 3-bevel tip.
• Universal fit: GlucoRx states that the needles fit all insulin pen devices.
• Designed for ease of injection: GlucoRx lists enhanced ease of injection and reduced injection time, without fragmentation, among the needle's key features.
• Single use: Each needle is used for one injection and then discarded, as GlucoRx advises never to reuse a pen needle.

Do GlucoRx FinePoint Ultra needles fit my insulin pen?

GlucoRx states that the needles have a universal fit on all insulin pen devices. Always follow your pen manufacturer's instructions for preparing the pen, and ask your healthcare team which needle length and pen suit you best.

Is a 4mm needle suitable for adults?

GlucoRx states that 4mm needles are mostly used in children, and 4mm, 5mm or 6mm needles in adults, depending on the injection site. Your healthcare professional should advise the needle length that is most suitable for you.

What is the difference between the 4mm and 4mm Ultra needles?

GlucoRx states that its 4mm, 4mm Ultra, 5mm, 6mm and 8mm needles all have a 5-bevel tip, unlike the 3-bevel tip of the other sizes in the FinePoint range. The GlucoRx leaflet does not describe any other difference between the 4mm and 4mm Ultra needles.

Why does insulin sometimes leak after I remove the needle?

GlucoRx says leakage can happen if the needle is not left under the skin long enough, so count slowly up to 10 before withdrawing it. If you use a skin fold, release the pinch before you remove the needle. Some leakage after withdrawing is not unusual, and GlucoRx states it should not affect your blood glucose control.

Materials: The manufacturer's leaflet does not state the needle materials.

Size: 4mm length, 32G, 5-bevel tip. Box of 100 needles.

Follow the instructions supplied with your insulin pen alongside these steps:

1. Load an insulin pen cartridge if necessary. Keep the pen and pen needles separate until you are ready to inject.
2. Remove the seal from a new pen needle and attach it to your pen using the outer protective cap. Check that the needle is attached securely, but not too tightly, so you can fully press the dose button.
3. Remove the outer protective cap, then the inner protective cap, carefully so you do not bend the needle.
4. Prime your pen to clear air bubbles and dead space and make sure insulin flows freely through the needle.
5. Dial in the exact dose you need.
6. Make sure your hands and the injection site are clean. Avoid injecting through clothes or where there are visible blood vessels. The stomach, thighs and buttocks are commonly used. Space successive injections at least 1cm apart.
7. Penetrate the skin quickly, then inject slowly, counting up to 10, into the layer under the skin with your muscles relaxed and the insulin at room temperature. Do not remove the needle too fast, as insulin may leak out and affect the dose.
8. Carefully replace the outer protective cap if you are injecting yourself, detach the needle and discard it immediately in a sharps container, following your local medical waste disposal rules.

With a 4mm needle, a 90 degree angle can be used if there is enough fatty tissue. If you are injecting into slim limbs or abdomen, a lifted skin fold may still be needed: pinch the skin between your thumb and index finger without including blood vessels or muscle. Never carry an insulin pen with the needle already attached, as this lets air enter the cartridge and slows the insulin dose.

Follow these precautions when using GlucoRx FinePoint Ultra needles:

• Never reuse a pen needle. Reuse can cause bacterial growth on the needle and a dull tip, which makes injections more painful and risks the needle breaking off or dislodging in your skin.
• Never share your insulin pen with anyone, because of the risk of cross-contamination.
• Ask your healthcare team to help choose the most suitable needle length and pen for you.
• Avoid injecting into sites with lipohypertrophy (lumpy skin), oedema, inflammation or infection until the problem has resolved, and never inject into lumps, because insulin does not absorb well there.
• Insulin accidentally injected into muscle will not be absorbed properly. It may be painful and cause high or low blood sugars.
• If you bleed frequently at the injection site, consult your healthcare professional about your injection technique or any other medical problem.
