6.Contents of the package and additional information

Abstralis a treatment for adultswho are already taking regular powerful pain medications (opioids)for their persistent cancer pain, but require treatment for breakthrough pain.If you are unsure, consult your doctor.

Breakthrough pain is a type of pain that appears suddenly, even though you have taken or used your usual opioid pain medication.

The active substance in Abstral sublingual tablets is fentanil. Fentanil belongs to a group of powerful pain medications called opioids.

Do not takeAbstral

?If you are allergic to fentanyl or any of the other components of this medication (listed in section 6)

?If you have severe breathing problems

• If you are not regularly using a prescribed opioid medication (e.g., codeine, fentanyl, hydromorphone, morphine, oxycodone, meperidine) every day at the same time, for at least one week, to control persistent pain. If you have not been using these medications, do not use Abstral as its use may increase the risk of your breathing becoming slower and/or shallower, and even stopping.
• If you have short-term pain that is not breakthrough pain.
• If you are receiving treatment with medications that contain sodium oxybate.

Warnings and precautions

Keep this medication in a safe and protected place, out of reach of others (see section 5 Abstral Storage for more information).

Consult your doctor or pharmacist before starting Abstral if you have or have had any of the following symptoms, as your doctor will need to take them into account when prescribing your dose:

?A head injury, as Abstral may mask the extent of the damage.

?Respiratory problems or myasthenia gravis (a condition characterized by muscle weakness).

?If you have heart problems, especially low heart rate.

• Low blood pressure.

?Liver or kidney disease, as your doctor may need to adjust your dose with more caution.

?Brain tumor and/or elevated intracranial pressure (increased pressure in the brain that causes severe headache, nausea, vomiting, and blurred vision).

?Mouth sores or mucositis (inflammation and redness of the inside of the mouth).

• If you are taking antidepressants or antipsychotics; see the section “Abstral use with other medications”.
• If you have ever had adrenal insufficiency or hormone deficiency (androgen deficiency) with the use of opioids.

When taking Abstral, inform your doctor or dentist that you are taking this medication if:

• You are about to undergo surgery.
• You feel pain or increased sensitivity to pain (hyperalgesia) that does not respond to a higher dose of the medication as prescribed by your doctor.
• You experience a combination of the following symptoms: nausea, vomiting, loss of appetite, fatigue, weakness, dizziness, and low blood pressure. Together, these symptoms may be an indication of a potentially life-threatening condition called adrenal insufficiency, in which the adrenal glands do not produce enough hormones.

Long-term use and tolerance

This medication contains fentanyl, an opioid. Repeated use of opioid analgesics may make the medication less effective (the body becomes accustomed to it, known as pharmacological tolerance). It is also possible that you may become more sensitive to pain when using Abstral. This is known as hyperalgesia. Increasing the dose of Abstral may continue to reduce pain for a time, but it may also be harmful. If you notice that the medication is losing its effectiveness, consult your doctor. Your doctor will decide whether it is better to increase the dose or to gradually reduce the use of Abstral.

Dependence and addiction

The repeated use of Abstral may also cause dependence, abuse, and addiction, which could lead to a potentially fatal overdose. The risk of these adverse effects may be higher with a higher dose and longer use. Dependence or addiction may cause you to feel a lack of control over the amount of medication you should use or the frequency with which you should use it. You may feel the need to continue using the medication even if it does not help to alleviate pain.

The risk of dependence or addiction varies from person to person. The risk of becoming dependent or addicted to Abstral may be higher if:

• You or any member of your family have abused alcohol or experienced dependence on it, prescription medications, or illegal drugs (“addiction”).
• You smoke.
• You have had any mental health problems (depression, anxiety, or personality disorder) or have been treated by a psychiatrist for other mental health conditions.

If you notice any of the following symptoms while using Abstral, it may be a sign of dependence or addiction.

• You need to use the medication for longer than indicated by your doctor.
• You need to use a higher dose than recommended.
• You are using the medication for reasons other than those prescribed, such as “to stay calm” or “to help you sleep”.
• You have made repeated and unsuccessful attempts to stop using the medication or control its use.
• You feel unwell when you stop using the medication (e.g., nausea, vomiting, diarrhea, anxiety, chills, tremors, and sweating), and you feel better once you take it again (“withdrawal symptoms”).

If you notice any of these signs, consult your doctor to determine the best course of treatment for you, when it is appropriate to stop the medication, and how to do it safely.

Sleep disorders

Abstral may cause sleep disorders, including sleep apnea (interrupted breathing during sleep) and sleep hypoxemia (low oxygen levels in the blood). Symptoms may include interrupted breathing during sleep, waking up at night due to lack of air, difficulty maintaining sleep, or excessive daytime sleepiness. If you or someone else observes these symptoms, contact your doctor to evaluate the possibility of reducing the dose.

Use in athletes

This medication contains fentanyl, which may produce a positive result in doping control tests.

Abstral use with other medications

Inform your doctor or pharmacist that you are taking, have taken recently, or may need to take any other medication (other than the opioid pain medications you take regularly for pain).

Some medications may increase or decrease the effects of Abstral. Therefore, if you start, change the dose, or stop treatment with the following medications, inform your doctor, as it may be necessary to adjust your Abstral dose:

?Certain types of antifungal medications 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 medications called protease inhibitors, which contain, for example, ritonavir (used to treat viral infections).

• Rifampicin or rifabutin (medications used to treat bacterial infections).
• Carbamazepine, phenytoin, or phenobarbital (medications used to treat seizures).
• Medications based on St. John's Wort (Hypericum perforatum).

?Medications containing alcohol.

• Medications called monoamine oxidase inhibitors (MAO), used to treat severe depression and Parkinson's disease. Inform your doctor if you have taken this type of medication in the last two weeks.
• Determined types of potent analgesics, called agonists/antagonists, such as buprenorphine, nalbuphine, and pentazocine (medications for pain). You may experience withdrawal symptoms (nausea, vomiting, diarrhea, anxiety, chills, tremors, and sweating) while using these medications.

Abstral may increase the effect of sedative medications, including:

• Otherpotent pain medications(opioid medications, e.g., for pain and cough)
• Some analgesics for neuropathic pain (gabapentin and pregabalin)
• General anesthetics (used to put you to sleep during surgery)
• Muscle relaxants
• Sleeping pills
• Medications used to treat
• • depression
  • allergies
  • anxiety (such as benzodiazepines, e.g., diazepam) and psychosis
• Medications containing clonidine (used to treat high blood pressure).

The use of Abstral at the same time as sedative medications, such as benzodiazepines, increases the risk of drowsiness, difficulty breathing (respiratory depression), and coma, and may be fatal. Therefore, the use of Abstral with sedative medications should only be considered when other treatment options are not possible.

However, if your doctor prescribes Abstral with sedative medications, you should limit the dose and duration of treatment.

Inform your doctor of all sedative medications you are taking and follow your doctor's instructions strictly about the dose. It may be helpful to inform friends or family members to recognize the signs and symptoms mentioned above. Contact your doctor if you experience these symptoms.

The risk of some other adverse effects increases if you are taking medications such as certain antidepressants or antipsychotics. Abstral may interact with these medications, and you may experience changes in mental state (e.g., agitation, hallucinations, coma) and other effects such as increased body temperature, increased heart rate, unstable blood pressure, and exaggerated reflexes, muscle rigidity, lack of coordination, and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). Your doctor will tell you if Abstral is suitable for you.

Abstral with food, drinks, and alcohol

Abstral may cause drowsiness in some people. Do not consume alcohol without consulting your doctor as it may make you feel more drowsy than usual.

Do not drink grapefruit juice during your treatment with Abstral as it may increase the adverse effects of Abstral.
