Pen Needles

For most adults, a 4 mm or 5 mm pen needle at 31G or 32G is recommended by current medical guidelines, regardless of body mass index. Shorter needles (4 mm) are the safest choice because they reliably reach the subcutaneous fat layer without risking intramuscular injection. If you are unsure, consult your diabetes care team for a personalised recommendation.

You should use a new pen needle for every single injection. Reusing needles causes the ultra-fine tip to bend and develop microscopic barbs, which increases pain and tissue damage. Repeated use also raises the risk of lipodystrophy – hardened lumps under the skin that impair insulin absorption.

Yes, virtually all pen needles on the market – including BD Ultra-Fine, NovoFine, and BRP Fine – use the universal ISO standard thread and fit all major insulin and GLP-1 pens from Novo Nordisk, Sanofi, Lilly, and others. You can choose any brand of pen needle regardless of which pen device you use.

The gauge (G) number indicates the needle’s thickness – the higher the number, the thinner the needle. A 32G needle (0.23 mm diameter) is thinner than a 31G needle (0.25 mm diameter), resulting in slightly less pain during injection. The difference is small but can be noticeable, especially for children or patients who inject multiple times daily.

Yes. Ozempic and Wegovy pens use the same universal pen needle connection as insulin pens. All pen needles in our collection – BD Ultra-Fine, NovoFine, and BRP Fine – are fully compatible with Ozempic, Wegovy, Trulicity, Victoza, and other GLP-1 receptor agonist pens. A 4 mm or 5 mm needle is typically recommended.

Yes, pen needles are classified as medical devices and are freely available without a prescription in Germany. You can order them directly from our online shop without needing a doctor’s prescription. However, patients with a prescription may be able to have the cost covered by their health insurance – check with your provider.

Used pen needles must be placed in a puncture-resistant sharps container – never in regular household waste. After injection, carefully recap the outer cap using the one-hand scoop technique, unscrew the needle, and drop it into the container. Once full, sealed sharps containers can be returned to most pharmacies in Germany free of charge.
