What Fentora is used for
Fentora contains a medicine called fentanyl citrate. It is a pain-relieving medicine
known as an opioid, which is used to treat breakthrough pain in adult patients with
cancer who are already taking other opioid pain medicines for their persistent (around-the-clock)
Breakthrough pain is additional sudden pain that occurs in spite of you having taken
your usual opioid pain-relieving medicines.
Opioid medicines are those that contain active ingredients such as morphine, fentanyl
citrate, codeine, methadone, oxycodone, pethidine or buprenorphine.
Ask your doctor if you have any questions about why Fentora orally disintegrating
tablets have been prescribed for you.
Your doctor may have prescribed it for another use.
Fentora is only available on a doctor's prescription.
Before you take it
Fentora is not suitable for everyone.
When you must not take it
Do not take Fentora if:
you suffer from short-term pain other than breakthrough pain, such as pain from injuries
or surgery, headaches or migraines
you have not been using a prescribed opioid pain medicine every day on a regular schedule,
for at least one week, to control your persistent pain. If you have not been using
these medicines you must not use Fentora, because it may increase the risk that breathing
could become dangerously slow and/or shallow, or even stop.
you are allergic (hypersensitive) to fentanyl, or any of the other ingredients of
Fentora (see list at the end of this leaflet)
you suffer from severe breathing problems or severe obstructive lung conditions
Do not take Fentora after the expiry date shown on the blister package label and the
Do not take Fentora if the packaging seems to have been opened or is damaged.
Things to be careful of
You can become addicted to Fentora even if you take it exactly as prescribed. Fentora
may become habit forming causing mental and physical dependence. If abused it may
become less able to reduce pain.
As with all other opioid containing products, your body may become used to you taking
Fentora. Taking it may result in physical dependence. Physical dependence means that
you may experience withdrawal symptoms if you stop taking Fentora suddenly, so it
is important to take it exactly as directed by your doctor.
Tolerance to Fentora may develop, which means that the effect of the medicine may
decrease. If this happens, more may be needed to maintain the same effect.
Continue taking your medicine for as long as your doctor tells you. If you stop having
this medicine suddenly, your pain may worsen and you may experience some or all of
the following withdrawal symptoms:
nervousness, restlessness, agitation, trouble sleeping or anxiety
body aches, weakness or stomach cramps
loss of appetite, nausea, vomiting or diarrhoea
increased heart rate, breathing rate or pupil size
watery eyes, runny nose, chills or yawning
Fentora given to the mother during labour can cause breathing problems and signs of
withdrawal in the newborn.
It is important that you do not exceed your recommended dose.
Before you start to take it
Tell your doctor if:
you have any allergies
you are pregnant or intend to become pregnant
you are breast feeding or planning to breast feed
your other opioid pain medicine you take for your persistent (around-the-clock) cancer
pain is not stabilized yet
you are suffering from any condition that has an effect on your breathing (such as
asthma, wheezing, or shortness of breath).
You have a head injury
You have exceptionally slow heart rate or other heart problems
You have liver or kidney problems, as these organs have an effect on the way in which
your system breaks down the medicine.
You have low amount of fluid in the circulation or low blood pressure
You have a history of addiction or substance abuse either personally or within your
You experience an unexplained increase in pain.
You feel anxious, irritable or have sudden mood swings, these could be signs of addiction
You notice any changes in hormones such as prolactin, testosterone and cortisol from
Your doctor should monitor you for these signs while on treatment. They may also conduct
blood tests from time to time to ensure you are responding as expected to treatment.
These organs have an effect on the way in which your system breaks down the medicine.

certain antibiotics such as clarithromycin and erythromycin

Fentora orally disintegrating tablets are for buccal use. When you place a tablet
in your mouth, it dissolves and the medicine is absorbed through the lining of your
mouth, into the blood system. Taking the medicine in this way allows it to be absorbed
quickly to relieve your breakthrough pain.
How many to take
When you first start Fentora, your doctor will work with you to find the dose that
will relieve your breakthrough pain. This process is called the titration process.
Please refer to the titration flowchart in the Patient's guide for Fentora section
of the leaflet for more information.
It is very important that you use Fentora exactly as the doctor tells you.
The initial dose is 100 micrograms. During determination of your right dose, your
doctor may instruct you to take more than one tablet per episode. If your breakthrough

pain. Your doctor will decide if your dose needs to be changed.
It is recommended that you wait at least 4 hours before treating another episode of
breakthrough pain with Fentora. The frequency may be increased if instructed by your
You must tell your doctor immediately if you are using Fentora more than four times
per day, as the doctor may wish to change your medicine for your persistent pain.
Once your persistent pain has been controlled, your doctor may need to change your
dose of Fentora further.
For the most effective relief, let your doctor know about your pain and how Fentora
is working for you so that the dose can be changed if needed.
Do not change doses of Fentora or your other pain medicines on your own. Any change
in dosage must be prescribed and monitored by your doctor.
