If your prescription has moved to a Lilly Tempo Pen, one of the first practical questions is which pen needles for Tempo Pen injections you should buy. The good news: the Tempo Pen is a disposable, prefilled insulin pen built around the same standard screw-on pen needle design as Lilly's KwikPen, so you don't need a special "smart" needle. This guide covers fit, sizing, how many to order, and a quick checklist before you check out.
What Is the Tempo Pen?
The Tempo Pen is a prefilled, disposable insulin pen from Eli Lilly that is designed to work with the Tempo Smart Button, an optional add-on that records dose information and sends it to a compatible app. Lilly has offered Tempo Pen versions of insulins such as Humalog, Lyumjev, and Basaglar. Which one you use, and your dose, is set by your prescriber.
The Smart Button attaches to the dose knob end of the pen. The needle end works like any other Lilly disposable pen, so needle choice is the same everyday decision KwikPen users already make.
Which Pen Needles Fit the Tempo Pen?
Tempo Pens accept standard screw-on pen needles. Major brands such as BD (Ultra-Fine and Nano 2nd Gen) and Novo Nordisk NovoFine and NovoFine Plus are widely used on Lilly disposable pens and are commonly listed as compatible with most US insulin pens. As always, your pen's Instructions for Use is the final word on which needles were tested, and your pharmacist can confirm fit if you're unsure.
Two popular options at Zahrun:
- BD Ultra-Fine 31G 5mm Pen Needles (100 count) – a familiar short needle many KwikPen users already know.
- NovoFine Plus 32G 4mm Pen Needles (100 count) – an extra-thin, short option designed for comfort.
Best Pen Needle Size for Tempo Pen Users
Size depends on you, not the pen. General guidance used by many diabetes educators:
- 4mm needles are long enough for most adults to reach the fat layer under the skin, usually injected at 90 degrees without pinching.
- 5mm or 6mm needles are sometimes preferred by people who are used to them or whose provider recommends them.
- Higher gauge numbers (31G, 32G) mean thinner needles, which many people find more comfortable.
If you're switching from a KwikPen and your current needle works well, you can usually keep the same size. Any change to injection technique or needle length should follow your healthcare provider's advice.
How Many Pen Needles Do You Need for a Tempo Pen?
The rule is simple: use a new needle for every injection, and remove it after each shot. Count your injections per day, multiply by 30, and add a small buffer for priming mistakes or a dropped needle.
- 1 injection a day: about 30–35 needles a month
- 3 injections a day: about 90–100 needles a month
- 4 or more injections a day: 120+ needles a month
People taking mealtime insulin like Humalog or Lyumjev several times a day often find a 100-count box lasts about a month, so a multi-box value pack can reduce reorders.
Tempo Pen Needle Checklist
- Attach a new needle straight on and screw it until snug.
- Remove both the outer cap and inner cap before priming.
- Do a safety (prime) shot before each dose, as your pen's instructions describe.
- Keep the Smart Button attached per Lilly's directions if you use it; the needle step doesn't change.
- Remove and discard the needle into a sharps container after every injection.
- Store unused needles at room temperature in their sealed packaging.
