Contents of the pack and other information
Abstral is a treatment for adults who are already taking regular, potent pain medicines (opioids)for their persistent cancer pain, but who need additional treatment for breakthrough pain. If you are not sure, ask your doctor.
Breakthrough pain is a type of pain that happens suddenly, even though you have been taking your usual opioid pain medicine for your persistent pain.
The active substance in Abstral sublingual tablets is fentanyl. Fentanyl belongs to a group of strong pain medicines called opioids.
Do not takeAbstral
? if you are allergic to fentanyl or any of the other ingredients of this medicine (listed in section 6)
? if you have severe breathing problems
Warnings and precautions
Keep this medicine out of the sight and reach of children and in a safe place to prevent abuse or theft.
Ask your doctor or pharmacist for advice before taking Abstral if you have or have had any of the following symptoms, as your doctor will need to consider this when prescribing your dose:
? a head injury, as Abstral may hide the extent of the damage.
? breathing problems or severe myasthenia (a condition characterized by muscle weakness).
? if you have heart problems, especially a slow heart rate.
? liver or kidney disease, as you may need your doctor to adjust the dose with more caution.
? brain tumour and/or increased intracranial pressure (increased pressure in the brain which causes severe headache, nausea, vomiting and blurred vision).
? mouth ulcers or mucositis (inflammation and redness of the inside of the mouth).
When taking Abstral, tell your doctor or dentist that you are taking this medicine if:
Long-term use and tolerance
This medicine contains fentanyl, an opioid. Repeated use of opioid pain medicines can make the medicine less effective (the body gets used to it, known as pharmacological tolerance). You may also become more sensitive to pain when using Abstral. This is known as hyperalgesia. Increasing the dose of Abstral may continue to relieve pain for a time, but it can also be harmful. If you notice that the medicine is becoming less effective, talk to your doctor. Your doctor will decide whether it is best for you to increase the dose or to gradually reduce your use of Abstral.
Dependence and addiction
Repeated use of Abstral can also lead to dependence, abuse and addiction, which could result in a potentially life-threatening overdose. The risk of these side effects may be greater with higher doses and longer use. Dependence or addiction can lead to a feeling of being unable to control the amount of medicine you need to use or how often you need to use it. You may feel a need to keep using the medicine even if it no longer helps your pain.
The risk of dependence or addiction varies from person to person. The risk of becoming dependent or addicted to Abstral may be greater if:
If you notice any of the following signs while using Abstral, it could be a sign of dependence or addiction.
If you notice any of these signs, talk to your doctor to determine the best course of treatment for you, when it is appropriate to stop the medicine and how to do so safely.
Sleep apnoea syndrome
Abstral may cause sleep apnoea syndrome (interrupted breathing during sleep) and hypoxia (low oxygen levels in the blood). Symptoms can include interrupted breathing during sleep, waking up during the night due to lack of air, difficulty staying asleep or excessive daytime sleepiness. If you or another person observe these symptoms, contact your doctor to consider reducing the dose.
Use in athletes
This medicine contains fentanyl which may produce a positive result in doping tests.
Using Abstral with other medicines
Tell your doctor or pharmacist that you are taking, have recently taken or might take any other medicines (apart from your regular opioid medicines for pain).
Some medicines can increase or decrease the effects of Abstral. Therefore, if you start, change the dose of or stop treatment with the following medicines, tell your doctor as they may need to adjust your dose of Abstral:
? certain types of antifungal medicines containing substances such as ketoconazole or itraconazole (used to treat fungal infections).
? certain types of antibiotics used to treat infections (called macrolides, containing substances such as erythromycin).
? certain types of antiviral medicines called protease inhibitors, which contain, for example, ritonavir (used to treat viral infections).
? medicines containing alcohol.
Abstral can increase the effect of medicines that make you feel drowsy (sedatives), including:
Taking Abstral with sedative medicines, such as benzodiazepines, increases the risk of drowsiness, breathing difficulties (respiratory depression) and coma, and can be life-threatening. For this reason, taking Abstral with sedative medicines should only be considered when other treatment options are not possible.
However, if your doctor prescribes Abstral with sedative medicines, they will limit the dose and duration of treatment.
Tell your doctor about all sedative medicines you are taking and follow your doctor’s instructions about the dose. It may be useful to inform friends or family members so they can recognise the signs and symptoms mentioned above. Contact your doctor if you experience these symptoms.
The risk of some other side effects increases if you are taking certain antidepressants or antipsychotics. Abstral may interact with these medicines and you may experience changes in your mental state (e.g. agitation, hallucinations, coma) and other effects such as body temperature above 38°C, increased heart rate, unstable blood pressure and exaggerated reflexes, muscle stiffness, lack of coordination and/or gastrointestinal symptoms (e.g. nausea, vomiting, diarrhoea). Your doctor will tell you if Abstral is suitable for you.
Abstral with food, drinks and alcohol
Abstral can cause drowsiness in some people. Do not drink alcohol without talking to your doctor as it may make you feel more drowsy than usual.
Do not drink grapefruit juice during treatment with Abstral as it may increase the side effects of Abstral.
Pregnancy and breast-feeding
Do not take Abstral during pregnancy unless your doctor has told you to do so.
Fentanyl can pass into breast milk and may cause side effects in the breast-fed baby. Do not use Abstral if you are breast-feeding. You should not start breast-feeding until at least 5 days after the last dose of Abstral.
Ask your doctor or pharmacist for advice before taking any medicine during pregnancy or breast-feeding.
Driving and using machines
Abstral can affect your ability to drive or use machines as it may cause drowsiness, dizziness or blurred vision.
If you feel dizzy, drowsy or have blurred vision while taking Abstral, do not drive or operate machinery.

Before taking this medication for the first time, your doctor will explain how you should take it to effectively treat your breakthrough pain.
Before starting treatment and regularly during treatment, your doctor will also explain what you can expect from using this medication, when and for how long you should use it, when you should contact your doctor, and when you should stop using it (see also section 2).

Abstral is a different type of medication from other medications you may have used to treat breakthrough pain. YOU SHOULD ALWAYS TAKE THE DOSE OF ABSTRAL AS DIRECTED BY YOUR DOCTOR;this may be a different dose from what you have used with other medications for breakthrough pain.
Starting Treatment – Finding the Right Dose
For Abstral treatment to be successful, your doctor will need to identify the right dose for treating your breakthrough pain. This medication is available in a wide range of doses. You may need to try different doses of the medication during different episodes of pain before finding the right dose. Your doctor will help you with this task and find the right dose for you.
If you do not get adequate pain relief with one dose, your doctor may tell you to take an additional dose to treat a breakthrough pain episode.
Do not take a second dose unless your doctor tells you to,as you may experience an overdose.
Your doctor may advise you to take a dose consisting of more than one tablet at the same time. ONLY DO THIS IF YOUR DOCTOR HAS TOLD YOU TO.
After taking the last dose, wait at least two hours before treating the next breakthrough pain episode with Abstral.
Continuing Treatment – Once the Right Dose is Established
Once you and your doctor have established a dose of Abstral that controls your breakthrough pain, you should not take this dose more than four times a day. A dose of the medication may consist of more than one tablet.
After taking the last dose, wait at least two hours before treating the next breakthrough pain episode with Abstral.
If you think the dose of the medication you are using does not control your breakthrough pain satisfactorily, tell your doctor, as you may need to have your dose adjusted.
Do not change your dose of this medication unless your doctor tells you to.
Taking the Medication
This medication should be used sublingually. This means you should place the tablet under your tongue, where it will dissolve quickly to allow fentanyl to be absorbed through the lining of your mouth. Once absorbed, fentanyl starts to work to relieve pain.
When you have a breakthrough pain episode, take the dose as directed by your doctor as follows:
If you take more of the medication than you should:
?Remove any remaining tablets from your mouth
?Tell your caregiver or another person what has happened
?Contact your doctor, pharmacist, or local hospital immediately and ask for advice on what to do
?While waiting for the doctor, keep the person awake by talking to them or shaking them occasionally
?An overdose can also cause a brain disorder known as toxic leukoencephalopathy.
Symptoms of an overdose include:
?Extreme drowsiness
? Shallow, slow breathing
If this happens, seek medical help immediately.

However, you should continue taking your usual opioid medications to treat persistent cancer pain as recommended by your doctor. You may experience withdrawal symptoms similar to the possible side effects of Abstral when you stop treatment with Abstral. If you have withdrawal symptoms or are concerned about pain relief, consult your doctor, who will assess whether you need any medication to reduce or suppress withdrawal symptoms.
If you have any further questions about using this medication, ask your doctor or pharmacist.
