How to Use VetPen®
Important dosage information
Doses of insulin are measured in units: 40 IU/ml insulin contains 40 International Units (IU) per millilitre (ml) (1 ml = 1 cc). VetPen is available in two sizes: 8 IU and 16 IU.
Your vet will prescribe Caninsulin® for your dog
Follow your vet’s instructions to properly give Caninsulin® to your dog. Your vet or vet nurse will:
- Determine the dosing and VetPen size for your dog
- Advise proper storage and handling
- Show how to prepare and prime VetPen
- Provide instructions on how to give the injection
When you feel comfortable you can do this correctly, your vet or vet nurse will provide you with everything you need to care for your dog at home.
There are six simple steps for using the VetPen.
- Insert the cartridge
- Attach the needle to the VetPen
- Prime the VetPen – remove any air bubbles
- Select the dose by dialling the dose selector
- Inject the dose by pressing the release button
- Remove the needle following injection
Please note, you do not need to prime with every dose just with the first use of the cartridge.
Step 1 – Inserting the cartridge
For best practice, we always recommend washing your hands before administration.
- Remove the cap from the VetPen.
- Unscrew the body of the VetPen from the cartridge holder.
- Check to ensure that the internal plunger is fully retracted. If the internal plunger is extended, rewind the internal plunger by holding the grey lower part of the pen body between the thumb and finger. Turn the pen body until the internal plunger is fully retracted.
- Carefully insert the cartridge into the cartridge holder with the metal cap of the cartridge at the top of the cartridge holder.
- Screw the cartridge holder onto the body of the VetPen ensuring you are firm but gentle.
Step 2 – Attaching the needle
VetPen needles are silicon-coated and designed to improve pet comfort.
- Carefully remove the paper tab from the outer needle as shown.
- Carefully, attach the capped needle onto the end of the VetPen by turning it clockwise until tight.
- Gently invert the VetPen up and down ten times. Always mix the insulin before each injection – this is crucial for insulin suspension such as Caninsulin to ensure accurate dosing.
Step 3 – Removing air bubbles (Priming the VetPen)
It is essential to remove air bubbles from the cartridge before using each cartridge for the first time only to avoid injection of air and incorrect dosing
- Ideally prepare the VetPen over the sink.
- Holding the VetPen vertically with the needle pointing up, remove the outer caps from the needle.
- Tap the VetPen gently with your finger to push any air bubbles to the top.
- Dial one unit on the dose selector by turning it clockwise.
- Push the release button, ensuring the dose selector is visible.
- Repeat the process until a steady stream of insulin is ejected from the tip of the needle. You may expect to eject as many as six to eight units of air before achieving this.
- Hold the VetPen horizontally to check that the cartridge is free of air bubbles, if not you need to repeat the above process until you’re bubble-free.
Please note: the cartridge contains two small beads to assist the mixing of insulin. These are not air bubbles.
- Ensure the arrow on your VetPen points to the start of the dose selector. Your VetPen is now ready for use.
Step 4 – Setting the dose
Turn the dose selector clockwise until you reach your prescribed dose.
If you have an unsteady hand or poor eye sight you can use the dose selector and release button adaptors.
Step 5 – Administering the injection
- The injection should be given under the skin, around the shoulder blade area with loose skin.
- Alternate sites with each dose, lifting the skin as shown in the demonstration video.
- Insert the needle under the skin horizontally.
- Press the release button and keep pressing and continue to hold the injection button firmly with your thumb until the dose selector arrow returns to the start line.
- Count to five then release the injection button.
Be sure to make a fuss of your dog. You could even give your pet a diabetes friendly treat. Providing positive reinforcement in this way helps to make the experience a positive one.
Step 6 – Removing the needle
- Remove the needle by inserting it into the needle remover and unscrewing it.
- Press the blue tip on the needle remover to release and dispose of the used needle, carefully and safely into the sharps pot.
Before dosing always check there are enough units in the cartridge. If there are not enough units, change the cartridge before starting.
Before changing the insulin cartridge, always make sure that the VetPen needle has been removed to prevent accidental injury.
Changing the cartridge
- Unscrew the cartridge holder from the VetPen body and remove the cartridge.
- Rewind the internal plunger by holding the white lower part of the Pen.
- Turn the Pen body clockwise until the internal plunger is fully retracted.
- Please note that incorrect re-winding of the internal plunger can result in damage to the VetPen.
- Return to step 1 to load the next cartridge.
Injection tips for VetPen use
- Always prepare the VetPen away from your pet
- In the event of over-dialling, dispose of the insulin in the sink and re-dial the correct dose. Dialling back the dose selector may damage the VetPen and result in inaccurate dosing
- If only a partial dose is delivered, wait until the next dose and give your cat or dog its usual dose. If you are in doubt, speak to your vet.
- X If only a partial dose is delivered, do not attempt to re-dose. If in doubt speak to your vet.
- X If insulin leaks out of the VetPen after injection check for small air bubbles. Do not attempt to re-dose. If you see a couple of drops after the injection, this is normal.
- X If you over-dial, never wind back the dose selector.
- X Do not re-cap or store the VetPen with the needle attached.
