HOW TO USE FENTANYL SANDOZ
Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions, ask your doctor or pharmacist for help.
How much to use
Ask your doctor or pharmacist if you are unsure of the correct dose for you.
They will tell you exactly which patch or patches to use.
Follow the instructions they give you.
If you use the wrong dose, Fentanyl Sandoz may not work as well in controlling your pain.
Fentanyl Sandoz is available in five different sizes. Your doctor will decide which patch, or combination of patches, is suitable
to control your pain.
Each patch is applied onto the skin and lasts for three days (72 hours). After three days, remove the patch and apply a new
patch to the skin at a different place.
You should not use more than one patch at a time, unless your doctor authorises otherwise (for example to obtain a dose that
cannot be achieved with a single patch). The old patch should be removed before the new patch is applied.
Fentanyl Sandoz should not be used in children under 12 years of age or in adolescents under 18 years of age who weigh less
than 50 kg.
The first patch may take up to a day to take effect after it is applied onto the skin. This is because fentanyl is slowly
absorbed through the skin into the blood. Your doctor may prescribe additional medicines to control your pain for the first
Applying the patch
Find an intact and hairless spot of skin on the upper part of your body or on your upper arm. Do not place the patch onto
skin that is red, burnt or damaged.
The skin should be healthy and undamaged.
Trim any excess hair with scissors. Do not shave the hair off since this may affect the skin. If you need to wash the skin
before applying the patch, use clean water only. Do not use soap, oils or lotions.
The skin should be completely dry before applying the patch.
Open the pouch and remove the Fentanyl Sandoz patch. Do not apply the patch if it looks damaged in any way. Never cut or divide
Remove the protective film.
Apply the patch to the skin and press with the palm of the hand for about 30 seconds. Make sure all of the patch is in contact
with skin and the corners are stuck tightly.
Wash your hands after applying or removing the patch.
You can now leave the patch on the skin for three days (72 hours).
You may have a bath, shower or swim.
Always write the date and time you applied the patch on the pack.
It will help you to use Fentanyl Sandoz correctly and remember when the next patch is due.
Changing the patch
After three days (72 hours), remove the patch.
Fold the used patch in half so that the adhesive side sticks to itself. Wrap the folded patch and carefully dispose of it
in the garbage.
Apply a new patch straight away to a different area of the skin, following the steps under 'Applying the patch'.
How long to use Fentanyl Sandoz
Continue using your medicine for as long as your doctor tells you.
If you forget to use it
Apply a new patch as soon as you remember, and continue to use Fentanyl Sandoz as you would normally.
If it is almost time for your next dose, skip the dose you missed and apply your next dose when you are meant to.
Do not use a double dose to make up for the dose that you missed.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to use your medicine, ask your pharmacist for some hints.
If you use too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone Australia 13 11 26 or New Zealand 0800 POISON
or 0800 764766) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else
may have used too much Fentanyl Sandoz. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
The most important symptom of an overdose is difficulty in breathing.
If a person using Fentanyl Sandoz has abnormally slow or weak breathing, remove the patch. Keep the person awake by talking
to them or gently shaking them every now and then.
