This leaflet answers some common questions about ABSTRAL.
It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking ABSTRAL against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.

What ABSTRAL is used for

The medicine is used to treat breakthrough cancer pain in adult patients with cancer who are already receiving and are tolerant to (maintenance) opioid therapy for chronic cancer pain. Breakthrough pain is a transient episode of otherwise controlled chronic cancer pain.
ABSTRAL belongs to a group of medicines called analgesics. It is an opioid analgesic and it acts by blocking pain and your emotional response to pain.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is only available on a prescription from your doctor.

Before you take ABSTRAL

When you must not take it

Do not take ABSTRAL if you have an allergy to:
any medicine containing fentanyl or citrate
any other similar medicines (such as other opioid analgesics)
any of the ingredients listed at the end of this leaflet
if you suffer from short-term pain other than breakthrough pain.
Some of the symptoms of an allergic reaction may include:
shortness of breath
wheezing or difficulty breathing
swelling of the face, lips, tongue or other parts of the body
rash, itching or hives on the skin.
Do not take ABSTRAL for other types of acute pain (e.g. post- operative pain, headache, migraine).
Do not take ABSTRAL if you are not already receiving (and are tolerant to) opioid maintenance therapy for cancer-related pain.
Do not take ABSTRAL if you are suffering from severe respiratory depression or severe obstructive lung conditions.
Do not give this medicine to anyone younger than 18 years of age.
Do not use this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.
If it has expired or is damaged, return it to your pharmacist for disposal.
If you are not sure whether you should start taking ABSTRAL, talk to your doctor or pharmacist.

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.
Tell your doctor if you have or have had any of the following medical conditions:
chronic obstructive pulmonary disease
difficulty breathing, wheezing, chronic cough, asthma or other chronic breathing condition
myasthenia gravis
hyperkapnia (too much carbon dioxide in the blood) or other evidence of increased intracranial pressure, reduced consciousness, coma or brain tumours
bradycardia (slow heart beat) or bradyarrhythmias
liver or kidney problems
low blood pressure
mouth wounds or mucositis (inflammation and ulceration of the mouth or gut lining).
Tell your doctor if you are pregnant or plan to become pregnant or are breastfeeding.
Fentanyl can get into breast milk and may cause side effects in the breast-fed infant. Do not use ABSTRAL if you are breastfeeding. You should not start breastfeeding until at least 5 days after the last dose of ABSTRAL. Your doctor can discuss with you the risks and benefits involved.
If you have not told your doctor about any of the above, tell him/her before you start taking ABSTRAL.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.
Some medicines may be affected by ABSTRAL, or may affect how well ABSTRAL works. These include:
some antibiotics (e.g. erythromycin)
some antifungal medicines (e.g. ketoconazole, itraconazole)
some antiviral medicines (e.g. ritonavir)
some medicines used to treat bacterial infections (e.g. rifampicin or rifabutin)
some medicines used to treat convulsions/fits (e.g. carbamazepine, phenobarbital or phenytoin)
other analgesics used to treat pain
antitussives (cough suppressants)
general anaesthetics
muscle relaxants
some antihistamines
medicines used to help you relax, sleep or relieve anxiety, such as barbiturates, benzodiazepines and other sedatives, antipsychotic agents, medicines used to treat mental disorders
some antidepressants e.g. phenelzine, selegiline. Taking ABSTRAL with these medicines may increase the risk of a potentially life-threatening condition called serotonin syndrome
certain types of strong pain killers, called partial agonist/antagonists e.g. buprenorphine, nalbuphine and pentazocine (medicines for treatment of pain). You could experience symptoms of withdrawal syndrome (nausea, vomiting, diarrhoea, anxiety, chills, tremor, and sweating) while using these medicines.
You may need different amounts of your medicine, or you may need to take a different medicine.
Your pharmacist or doctor will have more information on medicines to be careful with or avoid while using this medicine.

How to take ABSTRAL

Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
If your mouth is dry, take a sip of water to moisten it. Spit out or swallow the water.
STEP 1: Remove the tablet(s) from the blister pack immediately before use as follows:
Separate one of the blister squares from the pack by tearing along the dotted lines/perforations (keep the remaining blister squares together)
Peel back the edge of the foil as indicated by the arrow on the coloured strip, and gently remove the tablet.
Do not try to push ABSTRAL sublingual tablets through the foil top, as this will damage the tablet.
STEP 2: Place the tablet under your tongue as far back as you can, and let it dissolve completely.
ABSTRAL will dissolve rapidly under the tongue and be absorbed in order to provide pain relief.
It is therefore important that you do not suck, chew or swallow the tablet.
You should not drink or eat anything until the tablet has completely dissolved under your tongue.
STEP 3: Dispose of the empty blister square.
Do not substitute ABSTRAL for any other pain reliever. Use of ABSTRAL without dose titration and by individuals not already taking regular opioid medication may result in fatal overdose.
If you do not understand the instructions for use, ask your doctor or pharmacist for help.

How much to take

The recommended dosage will depend on the level of pain you are experiencing.

When starting ABSTRAL

You must start with the lowest dose tablet (100 microgram). If adequate pain relief is not achieved within 30 minutes, your doctor may recommend a supplemental (second) 100 mcg tablet.
If your pain is still uncontrolled after the second dose you cannot take another ABSTRAL tablet for this episode of pain.
If adequate pain relief was not achieved for an earlier episode of breakthrough cancer pain, your doctor may suggest you take additional tablets or higher strength tablets for your next episode(s) of breakthrough cancer pain. This is because everyone's pain is different and finding the right dose for you is important.
Do not take more than two doses of ABSTRAL for each episode of breakthrough cancer pain.
You should wait at least 2 hours before taking ABSTRAL to treat another episode of breakthrough cancer pain.

After you have found the right ABSTRAL dose

After you and your doctor have found the dose of ABSTRAL that provides adequate breakthrough cancer pain relief for you, this is the ongoing dose that you should take for each episode of breakthrough cancer pain.
You must tell your doctor immediately if you are using ABSTRAL more than four times per day, as the doctor may wish to change your medicine for your chronic cancer pain.
Once your chronic pain has been controlled, your doctor may need to change your dose of ABSTRAL further.
For best results, let your doctor know about your pain and how ABSTRAL is working for you so that the dose can be changed if needed.
Do not change doses of ABSTRAL or your other pain medicines on your own.
Contact your doctor if your recommended dose of ABSTRAL does not relieve your breakthrough cancer pain. Your doctor will decide if your dose needs to be changed.

How long to use it

You can use this medication whenever you have an episode of breakthrough pain.
You should discontinue ABSTRAL when you no longer have any breakthrough pain. You must however continue to take your usual opioid pain relieving medicine to treat your persistent cancer pain as advised by your doctor. You may experience withdrawal symptoms similar to the possible side effects of ABSTRAL when discontinuing ABSTRAL. If you experience withdrawal symptoms or if you are concerned about your pain relief you should contact your doctor. Your doctor will evaluate if you need medicine to reduce or eliminate the withdrawal symptoms.
Do not continue to use ABSTRAL if you no longer feel breakthrough cancer pain.

If you take too much (overdose)

Immediately telephone your doctor for advice, or go to Accident and Emergency at the nearest hospital if you think you or anyone else may have taken too much ABSTRAL. Do this even if there are no signs of discomfort or poisoning.

Do not switch from ABSTRAL to other medicines that contain fentanyl without talking with your doctor.
ABSTRAL is NOT interchangeable with other fentanyl products.
Your doctor will prescribe starting and maintenance doses of ABSTRAL that may be different than other fentanyl-containing medicines you may have been taking.
Do not take ABSTRAL for short-term pain that you would expect to go away in a few days, such as: pain from injuries, from doctors' or dentists' visits, surgery or headaches/migraines.
ABSTRAL can cause dizziness, drowsiness or blurred vision.
Do not drive or operate machinery while taking ABSTRAL as ABSTRAL can cause dizziness, drowsiness or blurred vision.
Do not consume alcohol while taking ABSTRAL, as dizziness and drowsiness may become worse.

Things to be careful of

ABSTRAL may be habit forming.
