Pen Needles for Rezvoglar KwikPen: Which Ones Fit and What Size to Choose

If you've been switched to Rezvoglar, or you're picking up your first box, one of your first questions will probably be which pen needles for Rezvoglar KwikPen you should buy. Rezvoglar (insulin glargine-aglr) is Eli Lilly's long-acting insulin biosimilar to Lantus. It comes in the familiar Lilly KwikPen format, and like other KwikPens it doesn't come with needles. This guide covers which needles fit, how to choose a length and gauge, and how to work out how many you need.

Do Pen Needles Fit the Rezvoglar KwikPen?

Yes. The Rezvoglar KwikPen uses the same standard threaded tip as other Lilly KwikPens, so it takes common screw-on pen needles. Major brands such as BD (Ultra-Fine and Nano) and NovoFine / NovoFine Plus are made to fit most major US insulin pens, KwikPens included. Before you order, check the compatibility list printed on the needle box. If a needle won't thread on smoothly, stop and don't force it.

Because Rezvoglar uses the same pen platform as Basaglar, much of our Basaglar KwikPen pen needle guide applies here too.

Choosing the Best Pen Needles for Rezvoglar KwikPen: Length and Gauge

Rezvoglar is injected into the fatty tissue just under the skin (subcutaneous), the same as other basal insulins. Widely published injection guidance has moved toward shorter needles because they reach that layer reliably for most adults.

• 4mm: the shortest common length. For most adults it reaches the subcutaneous layer, usually with no skin pinch.
• 5mm: a popular middle option, and a common choice for people who want a little more length.
• 6mm–8mm: still sold and used. A pinch-up or angled injection may be advised, especially for leaner people.

Gauge (G) describes thickness, and a higher number means a thinner needle. 32G needles are thinner than 31G, and many people find thinner needles more comfortable. Basal glargine doses can be fairly large, so some people also like needles designed for smooth flow, which can make the push feel easier.

Your healthcare provider or diabetes educator can tell you which length fits your body and technique. Follow their advice if it differs from these general guidelines.

Good Needle Options for a Rezvoglar Pen

• NovoFine Plus 32G 4mm (100 count): short and ultra-thin, a common pick for daily basal injections.
• BD Ultra-Fine 31G 5mm (100 count): a reliable, widely used option if you prefer a slightly longer needle.
• Browse every size and brand in our pen needles collection, including trial packs and multi-box value packs.

How Many Pen Needles Do You Need for Rezvoglar?

Use a new needle for every injection. If you take Rezvoglar once a day, that's about 30 needles a month, so a 100-count box lasts roughly three months. If you also use a mealtime insulin pen, count those injections too, since the same needles usually fit both pens. Keep a few extras for priming mistakes or a bent needle.

Quick Checklist Before Each Rezvoglar Injection

• Check the label to confirm the pen is Rezvoglar and that it hasn't expired.
• Attach a new needle straight on, then remove both the outer and inner caps.
• Do a safety test (prime) as described in the pen's Instructions for Use.
• Rotate injection sites to help prevent lumps under the skin.
• Hold the needle in the skin for the time the instructions specify.
• Remove the needle after each injection and put it in a sharps container. Don't store the pen with a needle attached.

FAQ

Does Rezvoglar KwikPen come with needles?
No. Pen needles are sold separately, and in the US they're often bought without a prescription. Rules can vary by state and insurance plan, so check your plan if you want coverage.

Can I use the same needles as my Lantus or Basaglar pen?
Generally yes. Standard screw-on pen needles from major brands fit these common pens. Always check the box's compatibility list.

Can I reuse a needle on my Rezvoglar pen?
It isn't recommended. Reused needles get duller and can bend or clog, and they raise the risk of infection.
