Novo Nordisk makes some of the most widely used injection pens in the US, from NovoLog and Tresiba insulin pens to Ozempic, Victoza, and Saxenda. Almost all of them are multi-dose pens that need a new screw-on needle for every injection. This family guide explains which pen needles for Novo Nordisk pens fit, what size most people use, which pens come with needles in the box, and how to stock up without guessing.
Which Novo Nordisk Pens Use Pen Needles?
Novo Nordisk pens sold in the US generally fall into a few groups. All of the following use separate, single-use pen needles:
- FlexPen insulin pens: such as NovoLog FlexPen, NovoLog Mix 70/30 FlexPen, Novolin FlexPen, and unbranded insulin aspart FlexPen.
- FlexTouch insulin pens: such as Tresiba FlexTouch, Fiasp FlexTouch, and unbranded insulin degludec FlexTouch.
- GLP-1 pens: the Ozempic pen, plus the Victoza and Saxenda pens.
- Reusable pens: NovoPen Echo, which takes insulin cartridges and screw-on needles.
The main exception is the Wegovy single-dose pen, which has a hidden built-in needle, so you don't buy separate pen needles for it. Your pen's Instructions for Use is always the final word. For a pen-by-pen look beyond Novo Nordisk, see our guide to which injection pens need pen needles.
Which Pen Needles Fit Novo Nordisk Pens?
Novo Nordisk's own needle line is NovoFine, including NovoFine Plus, and those needles are designed to work with its pens. But you aren't limited to one brand. Novo Nordisk pens use the standard screw-on connection shared by most US insulin and GLP-1 pens, so other major brands such as BD also make needles that fit. Check the compatibility list on the needle box and ask your pharmacist if you're unsure.

Popular choices for Novo Nordisk pens:
- NovoFine Plus 32G 4mm, 100-count box: Novo Nordisk's short, thin needle and the same type packed with US Ozempic pens.
- NovoFine Plus 32G 4mm 2-box value pack (200 needles): a lower cost per needle for people who inject daily or use more than one pen.

What Size Pen Needle for Novo Nordisk Pens?
Insulin and GLP-1 medicines from these pens are injected under the skin (subcutaneously). Widely used injection technique guidance favors short needles, such as 4mm or 5mm, for most adults because they reach the fat layer with less chance of going into muscle.
- Gauge: higher numbers are thinner. 32G is among the thinnest pen needles sold in the US.
- Length: 4mm is a common starting point and is usually injected straight in at 90 degrees for most adults.
- Bigger doses: a larger dose doesn't call for a longer needle. Holding the needle in the skin for the time your pen's instructions state helps you get the full dose.
- Your provider decides: if you were taught a specific length or technique, keep following it.
Do Novo Nordisk Pens Come With Needles?
It depends on the product. US Ozempic cartons include NovoFine Plus needles for the doses in the pen, though many people keep a spare box for dropped or bent needles. Most other Novo Nordisk pens, including Victoza, Saxenda, and the FlexPen and FlexTouch insulin pens, are typically sold without needles, so plan to buy them with your prescription. Check your carton to be sure.
How Many Pen Needles Will You Need?
Use a new needle for every injection, and count across all your pens:
- Once-weekly Ozempic: about 4 to 5 needles a month.
- Once-daily Victoza, Saxenda, or basal insulin: about 30 a month.
- Basal plus mealtime insulin (4 shots a day): about 120 a month.
Add a small buffer for mistakes. If you use several Novo Nordisk pens, one box in a length your provider approves can often cover all of them. GLP-1 users can also shop our pen needles for GLP-1 pens collection. Pen needles are generally an eligible FSA/HSA expense; check with your plan administrator.
Novo Nordisk Pen Needle Checklist
- Peel the paper tab and screw the needle on straight until snug.
- Remove both the outer cap and the thin inner cap.
- Do the flow check or prime as your pen's instructions describe.
- Remove the needle after every injection; don't store the pen with a needle on.
- Dispose of used needles in a sharps container.
- Never share a pen, even with a new needle.
FAQ
Do I have to use NovoFine needles on a Novo Nordisk pen?
No. Other standard screw-on needles, such as BD, are commonly used. Confirm your pen is on the box's compatibility list.
Do the same needles fit FlexPen and FlexTouch?
Yes, both use the same standard screw-on connection.
Can I reuse a pen needle?
No. Pen needles are single-use. Reusing one can dull the tip, clog the needle, and raise infection risk.
