Agujas para pluma: longitud, calibre y compatibilidad
La aguja debe corresponder al sistema de pluma concreto. Compare la referencia, las dimensiones y el formato indicado; la marca por sí sola no demuestra compatibilidad.
Diferencias de presentación
La selección reúne referencias BD y NovoFine, junto con variantes BRP. Las longitudes descritas incluyen 4, 5, 6 y 8 mm según el modelo. El calibre y el número de unidades también cambian: compruebe la variante concreta antes de elegir.
Longitud y calibre son datos distintos. Use la elección indicada para su dispositivo y sus necesidades; esta página no determina una técnica ni una dosis de inyección.
Consumibles relacionados
Las agujas para pluma no sustituyen jeringas de insulina. Puede compararlas en material para diabetes o revisar inyección y accesorios. Para una pluma GLP-1, compruebe específicamente el sistema en material de inyección GLP-1 y en las instrucciones del dispositivo.
Preguntas frecuentes (FAQ)
What pen needle size is right for me?
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.
How often should I change my pen needle?
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.
Are all pen needles universally compatible?
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.
What is the difference between 31G and 32G pen needles?
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.
Can I use pen needles for Ozempic or Wegovy?
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.
Are pen needles available without a prescription?
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.
How do I dispose of used pen needles properly?
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.
Can I buy pen needles on account (invoice)?
Yes, at Parahealth we offer purchase on invoice (Kauf auf Rechnung) as a payment option for customers in Germany. You receive your pen needles first and pay within the stated payment period. We also offer additional payment methods including PayPal, credit card, and instant bank transfer (Sofortüberweisung).
