How Long to Hold an Insulin Pen in the Skin: 5, 6, or 10 Seconds?

If you've ever pulled your pen out and spotted a drop of medicine on your skin, you've probably wondered how long to hold an insulin pen in the skin after pressing the button. The short answer: most pen instructions ask you to keep the needle in place for about 5 to 10 seconds after the dose counter returns to zero. The exact number depends on your pen, and getting it right helps make sure the full dose goes where it should.

How Long to Hold an Insulin Pen in the Skin: The Quick Answer

Pen manufacturers publish a specific hold time in each pen's Instructions for Use (IFU), the leaflet that comes in the box. Common examples include:

• Sanofi SoloStar pens (such as Lantus, Toujeo, and Admelog): the instructions say to count slowly to 10 before removing the needle.
• Novo Nordisk FlexPen and FlexTouch pens (such as NovoLog, Tresiba, Victoza, and Ozempic): the instructions generally say to keep the needle in for at least 6 seconds.
• Lilly KwikPen pens (such as Humalog and Basaglar): the instructions generally say to count slowly to 5.

Pen designs and instructions are updated from time to time, so treat your own pen's IFU as the final word. If you aren't sure, your pharmacist or diabetes educator can walk you through it.

Why the Hold Time Matters

When you press the dose button, the plunger inside the pen pushes medicine through a very thin needle. Even after the counter reads zero, the last bit of liquid is still moving out of the cartridge and into the tissue under your skin. Pulling out too soon can leave some of the dose behind. That can show up as a drop on the skin, a wet spot, or medicine dripping from the needle tip.

The hold time gives that last bit of liquid time to finish flowing. It's one of the simplest habits that helps you get the full dose your provider prescribed.

Does Needle Size Change How Long You Hold the Pen?

Not really. Whether you use a 4mm, 5mm, or 8mm needle, follow the hold time in your pen's instructions. Thinner needles, such as 32G, can feel more comfortable, but the hold time is set by the pen. A thin needle does not remove the need to wait.

Length still matters for comfort and for reaching the right tissue layer. Many adults use short needles like the NovoFine Plus 32G 4mm pen needles or the BD Ultra-Fine 31G 5mm pen needles. Your healthcare provider can help you pick a length that suits your body and technique.

Tips to Make the Count Easier

• Count slowly and out loud (or in your head). "One-Mississippi, two-Mississippi" works better than a quick count.
• Keep your thumb on the button during the count if your pen's instructions say to. Some do, so check yours.
• Hold the pen steady at a 90-degree angle unless your provider told you otherwise.
• Don't rub the site right after you remove the needle.
• Use a new needle every time. A dull or blocked needle can slow the flow and make leaking more likely.

If you still see medicine on your skin after holding for the full count, other causes may be involved. Our guide to insulin pen leaking after injection covers the most common ones.

Quick Checklist

• Attach a new pen needle and remove both caps.
• Do a safety test (priming) as your pen's instructions describe.
• Insert the needle and press the button until the counter shows 0.
• Hold for the time in your pen's IFU (often 5, 6, or 10 seconds).
• Remove the needle, then dispose of it in a sharps container.

FAQ

What happens if I pull the needle out too early?
Some of the dose may leak out onto your skin. Don't try to "make up" a missed amount on your own. Ask your healthcare provider what to do.

Is it a problem if I hold longer than the instructions say?
Holding a few extra seconds is generally fine and is a common habit for people who see leakage.

Does this apply to GLP-1 pens like Ozempic or Saxenda?
Yes. These pens have their own hold times in their IFUs, so check the leaflet for your specific pen.
