When it has reached room temperature, take the SmartJect pen or syringe out of the carton.
Wash your hands with warm soapy water and dry with a clean towel.
Use an alcohol wipe to clean a 5 x 5cm area around your chosen injection site and allow the skin to air dry.
Please choose either the SmartJect Pen or the Syringe:
Twist and remove the cap and then throw it away - don't put it back on as this may damage the needle. You should inject within 5 minutes of the cap being removed.
Check expiry date:
Check the expiration date (as indicated as "EXP") on the pre-filled pen.
You can also check the expiration date printed on the carton. Do not use the pre-filled pen if the expiration date has passed. The expiration date refers to the last day of the month. Please contact your doctor or pharmacist for assistance.
Make sure you are sitting comfortably with your muscles relaxed. Being careful not to push the button, press the SmartJect® pen firmly against your skin.
When you feel ready, you can inject by simply pressing the button - when the injection starts, you should hear a loud click. You will not be able to push down the button unless the pen is held firmly against the skin.
You may be startled by the click, but be careful not to move the pen once the injection has started.
Continue holding the pen firmly against the skin until you hear a second click - otherwise you may not receive the full dose. This should happen after 3-15 seconds.
If you have difficulty hearing, wait at least 15 seconds before moving the pen away.
If the injection has been successful, you should be able to see a yellow indicator. If you can’t see it, contact your healthcare professional, but do not take another dose.
Don’t worry if there is a small amount of blood or liquid at the injection site afterwards – this is normal. It may help to press on the area with a cotton ball, but do not rub the skin.
Hold the syringe in one hand between your thumb and fingers - you should only hold it by the main body of the syringe
Check expiry date:
Check the expiration date (as indicated by "EXP") on the label by looking through the viewing window located within the body of the pre-filled syringe.
If you cannot see the expiration date through the viewing window, hold the pre-filled syringe by its body and rotate the needle cover to line up the expiration date to the viewing window.
You can also check the expiration date printed on the carton. Do not use the pre-filled syringe if the expiration date has passed. The expiration date refers to the last day of the month. Please contact your doctor or pharmacist for assistance.
Pull the needle cover off and throw it away - don't put it back on as this may damage the needle.
Don’t worry if you notice a small air bubble or drop of liquid at the end of the needle - this is normal.
Gently hold the skin around the sterilised area using your thumb and index finger.
Holding the syringe like a pencil with your other hand, insert the needle at a 45° angle, with one quick motion, into the area of skin you are holding.
You should push the plunger down slowly but firmly, until all the fluid has been injected.
Keep the pressure on the plunger as you take the needle out.
Gradually take your thumb off the plunger, allowing the empty syringe to move up until the needle guard fully covers the needle.
Don’t worry if there is a small amount of blood or liquid at the injection site afterwards - this is normal. It may help to press on the area with a cotton ball, but do not rub the skin.
You will be given a sharps bin to dispose of all used pens or syringes.
Never throw away SmartJect pens or syringes with household waste.
You can organise the delivery and collection of your sharps bin by telephoning one of the numbers below, and asking to speak to a Patient Services Advisor.
