Insulin injection mistakes are more common than you might think3*

A study showed that people with diabetes were making at least one mistake in how they inject insulin.3* Insulin is meant to be injected into the fat layer just below the skin where it works best. Accidentally injecting insulin too deeply – into the muscle – can lead to pain or the chance of blood sugar dropping too low.4

“One of the things that Iʼm always worried about is how do I know that once I inject it into my body itʼs in the right place or itʼs actually working”†

Experience more comfortable and confident injections1-2

Micro-Fine UltraTM Pen Needles have innovative features proven to provide an easier, more comfortable injection experience, and confidence that the complete dose of insulin has been delivered.1,2‡§

Accuracy with a shorter needle

Micro-Fine UltraTM 4mm Pen Needles help reduce the risk of injecting into your muscle compared to needles 6mm and longer.5,||

Comfort with a 5-bevel tip

In a study, the 5-bevel tip was shown to offer a more comfortable and less painful injection experience compared to similar length 3-bevel pen needles.2§

Confidence with
Ultra-Thin wall technology

Ultra-Thin wall technology increases the flow of insulin, making injections easier and giving you the confidence that you have received the full dose.1#
Ultra-Thin wall is the highest ISO standard for a 32G pen needle inner diameter.6

Micro-Fine UltraTM and VivaTM Pen Needles are compatible with widely used pen injectors. Even if your injection therapy changes, you can still use Micro-Fine UltraTM and VivaTM Pen Needles.7
