Semaglyn 1 Reusable Customized Pen is a reusable medical delivery device from Zydus Healthcare designed specifically for use with Semaglyn semaglutide injection cartridges. The pen itself does not contain semaglutide or any other medicine. It is used to deliver the medicine from the compatible cartridge under the skin.
What is Semaglyn 1 Reusable Customized Pen used for?
Semaglyn 1 Reusable Customized Pen is designed to administer compatible Semaglyn semaglutide injection cartridges.
The device allows the medicine contained in the cartridge to be delivered subcutaneously. Zydus developed the reusable pen to allow different prescribed semaglutide doses to be administered from a reusable device rather than requiring a separate single-use pen for every dose strength.
The weight-management effect comes from semaglutide in the cartridge, not from the pen itself.
Does Semaglyn Pen contain semaglutide?
No, The Semaglyn 1 Reusable Customized Pen is a non-consumable medical device. The compatible semaglutide medicine comes separately in a prefilled cartridge. Pharmacy information specifically identifies the reusable pen as a device and distinguishes it from the prefilled cartridge variant.
The currently marketed Semaglyn semaglutide cartridge contains 15mg of semaglutide in 3mL, equivalent to 5mg/mL.
How does the It work?
The pen is designed to hold the compatible Semaglyn semaglutide cartridge.
In general, the process involves:
- Installing the compatible cartridge into the reusable pen.
- Attaching a new sterile needle.
- Selecting the prescribed dose according to the pen instructions.
- Administering the injection under the skin.
- Removing and safely disposing of the used needle.
- Keeping the reusable pen for subsequent injections according to the manufacturer’s instructions.
Because the pen is a dose-delivery device, the manufacturer’s instructions supplied with the specific pen should always be followed. Do not estimate doses by counting clicks or modify the device.
Is Semaglyn Pen used for weight loss?
The pen itself does not cause weight loss. Its role is to deliver semaglutide from a compatible cartridge.
Semaglutide can help with weight management by acting on appetite and satiety pathways. Australian Healthdirect information explains that GLP-1 medicines such as semaglutide can reduce hunger and slow digestion, helping people feel fuller for longer.
How to use It
The Semaglyn pen should be used only with the compatible Semaglyn injection cartridge.
Before using the device:

- Inspect the cartridge for damage.
- Attach a new sterile needle as instructed.
- Follow the dose prescribed by your doctor.
- Inject only into the recommended subcutaneous areas.
- Dispose of the needle safely after use.

Can the Semaglyn Pen be shared?

Sharing a pen can create a risk of cross-contamination and transmission of infections because the device may come into contact with blood or other biological material.

4. Can the Semaglyn pen be carried while travelling?
