If you've been prescribed Toujeo, you've probably noticed that the pen box doesn't include needles. Pen needles for Toujeo SoloStar (and Toujeo Max SoloStar) are sold separately, so you need to choose a length, gauge, and pack size yourself. This guide explains which pen needles fit, how to think about size, and how many to order so you don't run short.
Do Standard Pen Needles Fit Toujeo SoloStar?
Yes. Toujeo SoloStar and Toujeo Max SoloStar use the common screw-on needle connection shared by most US insulin pens. That means widely used brands such as NovoFine, NovoFine Plus, BD Nano, and BD Ultra-Fine pen needles thread onto the pen tip the same way they do on other SoloStar pens. If you've already read our guide to pen needles for Lantus SoloStar, the same compatibility logic applies here.
A few practical notes:
- Toujeo SoloStar holds 1.5 mL and Toujeo Max SoloStar holds 3 mL. Both take the same pen needles.
- Screw the needle on straight and snug. Cross-threading is a common reason a needle feels loose or leaks.
- Always follow the safety test described in your pen's Instructions for Use before each injection.
What Size Pen Needle Is Best for Toujeo?
Pen needle size has two parts: length (in millimeters) and gauge (G, where a higher number means a thinner needle). Toujeo is injected into the fatty tissue under the skin, and current injection guidance from diabetes educators notes that short needles, such as 4mm, reach that layer for most adults regardless of body size.
- 4mm, 32G: the shortest, thinnest common option. Many people choose it for comfort, and it usually doesn't require pinching the skin.
- 5mm, 31G: a little longer, still very fine. A good choice if you're used to a slightly longer needle.
- 6mm and 8mm: longer options some people were started on years ago. Some may need a skin pinch to avoid injecting into muscle.
For a deeper comparison, see 4mm vs 6mm vs 8mm pen needles. If you're unsure which length is right for you, ask your healthcare provider or diabetes educator.
Popular Pen Needles for Toujeo SoloStar
These are common choices people use with Toujeo pens:
- NovoFine Plus 32G 4mm Pen Needles (100 count): ultra-thin and short, designed for a smooth, low-force injection.
- BD Ultra-Fine 31G 5mm Pen Needles (100 count): a trusted BD option at a slightly longer length.

How Many Pen Needles Do You Need for Toujeo?
Toujeo is usually taken once a day, and pen needles are designed for a single use. A simple rule of thumb:
- Once daily: about 30 needles per month, so a 100-count box lasts a little over three months.
- If you also use a mealtime insulin pen, add one needle per extra injection.
- Keep a few spares for a bent needle, a failed safety test, or travel.
Buying a larger value pack can lower your price per needle if you use the same size long-term.
Quick Checklist Before You Order
- Confirm you have Toujeo SoloStar or Toujeo Max SoloStar (both take standard screw-on pen needles).
- Pick a length and gauge you and your provider are comfortable with (4mm 32G is a popular starting point).
- Estimate your monthly needle count and add spares.
- Use a new needle for every injection, and remove it after injecting.
- Dispose of used needles in an FDA-cleared sharps container or a sturdy household alternative allowed in your area.
FAQ
Does Toujeo come with pen needles?
No. Pen needles are sold separately, so you'll need to buy them in addition to your pens.
Can I use NovoFine needles on a Sanofi pen like Toujeo?
Yes. NovoFine and NovoFine Plus use the standard screw-on connection and are commonly used on SoloStar pens.
Should I leave the needle on between doses?
No. Removing the needle after each injection helps prevent leaking, air bubbles, and contamination.
