How to Use VetPenTM
4 Load the insulin cartridge into the cartridge
holder by inserting the metal cap in first.
Failure to follow these instructions may result
in an inaccurate dose.
Insulin cartridges from any supplier other than
Intervet/Schering-Plough Animal Health should
not be used with either VetPen.
Loading a cartridge
1 Prior to loading, turn the insulin cartridge
5 Screw the cartridge holder and pen body
firmly together.
up and down at least 10 times until the
insulin appears uniformly milky. Do not
use if there are agglomerates in the
insulin after mixing thoroughly.
2 Pull off the pen cap and unscrew the pen
body from the cartridge holder.
Priming the insulin pen
Steps 6 through 8 must be followed before
each injection.
6 Peel the protective film from a new pen
needle. Screw the pen needle straight onto
the cartridge holder. Remove the outer
protective needle cap from the pen needle.
3 Check to ensure that the internal plunger
is fully retracted. If the internal plunger is
extended, please refer to step 13 to see
how to wind it back in.
Priming the insulin pen (cont.)
Replace the pen cap onto the insulin pen.
Turn the pen up and down at least 10 times.
Repeat steps 7 and 8 until a drop of insulin
appears at the needle tip. The insulin pen is
now ready for use.
If the start line (—) on the dose selector
does not return to the arrow (u) on the pen
body, please refer to the Priming Advice
information at the end of these instructions.
Injecting the dose into your pet
9 Make sure the arrow (u) on the pen body
points to the start line (—) on the dose
7 It is important to prime the pen before
use to avoid injection of air and ensure
proper dosing. Dial one unit on the dose
selector. Remove the pen cap.
Dial up the number of units required per
your veterinarian’s direction. (The dose
shown in this photograph is an example
only. Your veterinarian will tell you the
recommended dose for your dog or cat.)
8 Hold the pen with the needle pointing up.
Tap the cartridge gently with your finger a
few times to push any air bubbles to the top
of the cartridge. Push and hold the release
button towards the needle until the arrow (u)
on the pen body points to the starting line
(—) on the dose selector.
Never attempt to forcefully dial back
the dose selector, as doing so may
damage the insulin pen and result in
inaccurate dosing.
Injecting the dose into your pet (cont.)
If at any time you overdial the dose,
we recommend that the incorrect
dose is fully expelled into a safe place
and the required dose is redialed. Make
sure before injecting that the arrow (u)
points towards the correct number of
units on the dose selector.
Removing the needle
11 Remove the needle by inserting it in the
removal device and unscrewing it. Press
the blue tip on the device to release the
needle. Always check that your pen needle
has been removed.
10 The injection should be performed subcutane-
ously, 2 to 5 cm (3/4 to 2 in) from the dorsal
midline, varying from behind the scapulae
to the mid-lumbar region and alternating
sides. Insert the needle using the injection
technique recommended by your veterinarian then push the release button towards
the pen needle and hold it in place until the
start line on the dose selector returns to
the arrow on the pen body (u —).
Count to 5 before removing the needle from
the skin.
If the dose selector stops before the start line
(—) returns to the arrow (u), this indicates
that your pet has not received a full dose.
If only a partial dose was administered, do
not attempt to re-dose. Wait and give your
pet its usual dose at the next injection.
If your pet dislodges the needle before
the count of 5, do not attempt to re-dose.
Wait and give your pet its usual dose at
the next injection.
Replace the pen cap onto the insulin pen.
Dispose of used pen needles carefully in
accordance with the advice given by your
veterinarian or local regulations.
Changing the cartridge
12 Before changing the cartridge, always make
sure that the pen needle has been removed
to prevent accidental injury. Then unscrew
the cartridge holder from the pen body and
remove the cartridge.
Safety Precautions
etPen should be used only after
consultation with your veterinarian.
• P lease refer to the Caninsulin® cartridge
package insert for relevant storage conditions
for the insulin prior to and during use.
• Always ensure that VetPen has been primed
in accordance with the instructions detailed
in steps 7 and 8. Failure to follow the exact
priming procedures could result in an
inaccurate dose being delivered.
13 Rewind the internal plunger by holding the
gray lower part of the pen body between the
thumb and finger. Turn the pen body until
the internal plunger is fully retracted. Then
return to step 1 to load the next cartridge.
• To avoid potential damage to the VetPen,
never dial a dose and push the release button
without a cartridge in the cartridge holder.
• A new needle should be used for each
he needle should be removed with the needle
remover and safely disposed of immediately
after each injection. If the needle is left on

onsult your veterinarian should you encounter
difficulty in injecting your pet or should your
pet display any changes in behavior or clinical
Storage and Cleaning
VetPen should always be stored or carried with
the needle removed, and the pen cap on. To
clean VetPen, wipe with a damp cloth. Do not
immerse in water.
Note: If the internal plunger is rewound
incorrectly it can damage the VetPenTM.
Priming Advice
If the dose selector does not return to the
start line, and no insulin has been expelled,
this may indicate one of two possibilities.
1 The pen needle that you are using may be
blocked. Remove the pen needle currently
attached to the pen and replace it with a new
one. Then return to steps 7 and 8.
2 The cartridge plunger may require releasing.
If so:
A. Replace the outer protective cap onto the
B. Unscrew the cartridge holder.
C. Slide the release button towards the
internal plunger and hold in place until
the start line on the dose selector returns
to the arrow on the body.
D. Dial up 2 units on the dose selector
without screwing the internal plunger
back together and simply push and
hold down the release button towards
the internal plunger until the start line
on the dose selector returns to the
arrow on the body.
E. Without rewinding the internal plunger,
screw the cartridge holder and body
firmly together. This will release the
cartridge plunger and expel some of the
insulin. However, the device will not
be primed.
F. R
epeat steps 7–8, thus priming the
device fully.
