The reusable pen injector is pen injectors for medical use who require frequent, precise injections (e.g., insulin for diabetes, growth hormones, or autoimmune therapies). Unlike disposable injectors, it allows users to replace empty medication cartridges while keeping the pen body for repeated use, reducing waste and long-term costs.
Loading the Cartridge: The user inserts a pre-filled medication cartridge into the pen.
Dose Selection: A dial or digital display lets patients adjust the dose.
Needle Attachment: A new disposable needle is screwed onto the pen tip for hygiene.
Injection: Pressing a button or plunger delivers the medication subcutaneously (under the skin).
Reuse: After each use, only the needle is discarded; the pen is reused with a fresh cartridge.
Key Features:
Precision dosing (especially critical for insulin).
Ergonomic design for ease of self-administration.
Sustainability (fewer disposable parts vs. single-use pens).
Yes! Reusable pen injectors reduce plastic waste by 60-80% compared to disposable pen injector, as only needles and cartridges are replaced, not the entire device.
Reusable pen injectors primarily work with insulin, GLP-1 agonists (e.g., Ozempic), growth hormones, and select autoimmune therapies – always cartridge-specific.
Clean & Maintain Insulin Pen: Wipe with alcohol swab (avoid cartridge/needle). Never soak. Store at room temp. Replace needle after each use.
