1. What is Effentora and what is it used for

The active substance of Effentora is fentanyl citrate. Effentora is a medicine for the treatment of pain, this medicine is known as an opioid used to treat breakthrough pain in adult patients who are already receiving opioid treatment for their persistent (always present) cancer pain.

Breakthrough pain is a pain that comes on quickly and is in addition to the persistent pain that you already have, despite your regular pain medication.

2. What you need to know before you use Effentora

Do not use Effentora:

• if you are not already using a prescribed opioid medicine every day, at the same time, for at least one week to control your persistent pain. If you have not been using these medicines, do not useEffentora as its use can increase the risk of your breathing becoming slower and/or shallower and even stopping.
• 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 or severe obstructive lung disease.
• if you have short-term pain other than breakthrough pain.
• if you are taking a medicine that contains sodium oxybate.

Warnings and precautions

During treatment with Effentora, continue to use the opioid pain medicine that you take for your persistent (always present) cancer pain.

While being treated with Effentora, do not use other fentanyl treatments that you may have been prescribed previously for breakthrough pain. If you still have these fentanyl products at home, contact your pharmacist who will advise you how to dispose of them.

Repeated use of the product may reduce the effectiveness of the medicine (you may get used to it) or may lead to dependence on the medicine.

Tell your doctor or pharmacist BEFOREyou start using Effentora:

• if the other opioid medicine that you take for your persistent (always present) cancer pain has not yet been stabilised.
• if you have any breathing problems (such as asthma, wheezing or shortness of breath).
• if you have head injuries.
• if you have an exceptionally low heart rate or other heart problems.
• if you have liver or kidney problems, as these organs affect how your body breaks down the medicine.
• if you have low blood volume or low blood pressure.
• if you are over 65 years old; you may need a lower dose and your doctor will review any dose increases carefully.
• if you have heart problems, especially a low heart rate.
• if you are taking benzodiazepines (see section 2, “Using Effentora with other medicines”). The use of benzodiazepines can increase the risk of serious side effects, including death.
• if you are taking antidepressants or antipsychotics (selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), monoamine oxidase inhibitors (MAOIs)); see section 2, “Do not use Effentora” and “Using Effentora with other medicines”. The use of these medicines with Effentora can cause a potentially life-threatening condition called serotonin syndrome (see section 2, “Using Effentora with other medicines”).
• if you have ever had adrenal insufficiency, a condition where the adrenal glands do not produce enough hormones, or a lack of sex hormones (androgen deficiency) with the use of opioids (see section 4, “Serious side effects”).
• if you have ever had abuse or dependence problems with opioids or any other drug, alcohol or medication.
• if you drink alcohol, see the section “Using Effentora with food, drinks and alcohol”.

You may need to be closely monitored by your doctor:

• if you or a family member have ever had problems with abuse or dependence on alcohol, prescription drugs or street drugs (“addiction”).
• if you are a smoker.
• if you have ever had problems related to your mood (depression, anxiety or personality disorder) or have been treated by a psychiatrist for other mental health diseases.

Tell your doctor DURINGtreatment with Effentora:

• if you feel pain or increased sensitivity to pain (hyperalgesia) that does not respond to a higher dose of the medicine as prescribed by your doctor.
• if you have a combination of the following symptoms: nausea, vomiting, loss of appetite, fatigue, weakness, dizziness and low blood pressure. Together, these symptoms can be a sign of a potentially life-threatening condition called adrenal insufficiency, where the adrenal glands do not produce enough hormones.
• if you have sleep-related breathing disorders: Effentora may cause sleep-related breathing disorders such as sleep apnoea (pauses in breathing during sleep) and sleep-related hypoxemia (low oxygen levels in the blood). Symptoms may include pauses in breathing during sleep, waking up at night due to difficulty breathing, difficulty staying asleep or excessive daytime sleepiness. If you or someone else notices these symptoms, contact your doctor. Your doctor may consider reducing the dose.
• repeated use of Effentora can lead to dependence and abuse that can cause a potentially life-threatening overdose. If you are concerned about becoming dependent on Effentora, it is important that you talk to your doctor.

Seek IMMEDIATEmedical attention:

• if you notice symptoms such as difficulty breathing or dizziness, swelling of the tongue, lips or throat while using Effentora. These can be early signs of a severe allergic reaction (anaphylaxis, hypersensitivity; see section 4, “Serious side effects”).

What to do if someone accidentally takes Effentora

If you think someone has accidentally taken Effentora, seek immediate medical attention. Try to keep the person awake until the emergency services arrive.

If someone accidentally takes Effentora, they may experience the same side effects as described in the section “If you use more Effentora than you should”.

Children and adolescents

Do not give this medicine to children and adolescents under 18 years of age.

Using Effentora with other medicines

Tell your doctor or pharmacist before you start treatment with Effentora if you are taking, have recently taken or might take any other medicines, including:

• the use of Effentora and sedative medicines, such as benzodiazepines or related drugs, increases the risk of drowsiness, breathing difficulties (respiratory depression) and coma and can be life-threatening. Therefore, their use together should only be considered when other treatment options are not possible.

However, if your doctor prescribes Effentora with sedative medicines, the dose and duration of concomitant treatment should be limited by your doctor.

Tell your doctor about all sedative medicines you are taking (such as sleeping pills, medicines to treat anxiety, some medicines to treat allergic reactions [antihistamines] or tranquilisers) and follow your doctor’s dose recommendations strictly. It may be useful to inform friends or family members to alert them to the signs and symptoms described above. Contact your doctor if you experience these symptoms.

• certain muscle relaxants, such as baclofen, diazepam (see also the section “Warnings and precautions”).
• any medicine that may affect how your body breaks down Effentora, such as ritonavir, nelfinavir, amprenavir and fosamprenavir (medicines that help control HIV infection) or other inhibitors of the so-called CYP3A4, such as ketoconazole, itraconazole or fluconazole (used to treat fungal infections), troleandomycin, clarithromycin, or erythromycin (medicines for the treatment of bacterial infections), aprepitant (used for severe nausea) diltiazem and verapamil (medicines to treat high blood pressure or heart diseases).
• monoamine oxidase inhibitors (MAOIs) (used for severe depression), even if you have used them in the last two weeks.
• certain potent painkillers, called partial agonist/antagonists, such as buprenorphine, nalbuphine and pentazocine (medicines to treat pain). While using these medicines, you may experience symptoms of a withdrawal syndrome (nausea, vomiting, diarrhoea, anxiety, shivering, tremor and sweating).
• The risk of side effects increases if you are taking medicines such as certain antidepressants or antipsychotics. Effentora may interact with these medicines and you may experience changes in mental status (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 Effentora is suitable for you.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Using Effentora with food, drinks and alcohol

• Effentora can be taken before or after meals, but not during meals. You can drink a little water before using Effentora to help moisten your mouth, but do not drink or eat anything while taking the medicine.
• Do not drink grapefruit juice while using Effentora, as it may affect how your body breaks down this medicine.
• Do not drink alcohol during treatment with Effentora. It can increase the risk of serious side effects, including death.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.

Pregnancy

Effentora should not be used during pregnancy, unless you have discussed this with your doctor.

If Effentora is used for a long time during pregnancy, there is a risk that the newborn baby will have withdrawal symptoms that can be life-threatening if not recognised and treated by a doctor.

Do not use Effentora during labour, as fentanyl can cause breathing difficulties in the newborn baby.

Breast-feeding

Fentanyl may pass into breast milk and cause side effects in the breast-fed baby. Do not use Effentora if you are breast-feeding. You should not start breast-feeding until at least 5 days after the last dose of Effentora.

Driving and using machines

Ask your doctor if you can drive or use machines safely after taking Effentora. Do not drive or use machines if: you feel drowsy or dizzy, you have blurred vision or double vision or you have difficulty concentrating. It is important that you know how you react to Effentora before you drive or use machines.

3. How to use Effentora

Follow your doctor's administration instructions for this medication exactly. If you are in doubt, consult your doctor or pharmacist again.

Dosage and frequency

When you start using Effentora for the first time, your doctor will help you find the dose that will relieve your breakthrough pain. It is very important that you use Effentora exactly as your doctor indicates. The initial dose is 100 micrograms.

During the determination of the correct dose for you, your doctor may have you take more than one tablet per episode. If the breakthrough pain is not relieved after 30 minutes, use only 1 more Effentora tablet during the dose adjustment period.

Once you have determined the correct dose with your doctor, use 1 tablet for a breakthrough pain episode as a general rule. The dose of pain reliever you need may vary throughout treatment. You may need higher doses. If the breakthrough pain is not relieved after 30 minutes, use only 1 more Effentora tablet during this dose readjustment period.

Consult your doctor if your correct dose of Effentora does not relieve your breakthrough pain. Your doctor will decide if it is necessary to modify your dose.

Wait at least 4 hours before treating another episode of breakthrough pain with Effentora.

You should inform your doctor immediately if you need to take Effentora more than four times a day, as it may be necessary to change your treatment regimen. Your doctor may change the treatment you are receiving to control persistent pain; when the persistent pain is controlled, your doctor may need to change your dose of Effentora. If your doctor suspects increased sensitivity to pain (hyperalgesia) related to Effentora, a reduction in the dose of Effentora may be considered (see section 2, in "Warnings and precautions"). For more effective relief, inform your doctor of the pain you are experiencing and how Effentora is working in your case, so that they can modify the dose if necessary.

Do not change the doses of Effentora or other pain relievers on your own. Any change in dosage must be prescribed and monitored by your doctor.

If you are unsure of the correct dose or want to ask a question about using this medication, contact your doctor.

Method of administration

The method of administration of Effentora oral tablets is by mouth. When you place a tablet in your mouth, it dissolves and the medication is absorbed through the oral mucosa and into the bloodstream. This way of taking the medication allows it to be absorbed quickly to relieve your breakthrough pain.

How to use the medication

• Open the blister pack only when you are going to use the tablet. The tablet must be used immediately after removing it from the blister pack.
• Separate one of the units from the blister pack by tearing along the perforations.
• Fold the blister unit along the indicated line.
• Peel off the back of the blister pack to expose the tablet. DO NOT try to press the tablet to remove it from the blister pack, as this may damage it.

• Remove the tablet from the blister pack and place it immediatelywithout breaking it near a molar, between the gum and the cheek (as indicated in the photograph). Your doctor may also indicate that you place the tablet under your tongue.
• Do not attempt to crush or break the tablet.

• Do not bite, suck, chew, or swallow the tablet, as this will make it have a lesser analgesic effect than if you follow these instructions.
• The tablet should remain between your cheek and gum until it dissolves, which usually takes between 14 and 25 minutes.
• You may feel a slight effervescent sensation between your cheek and gum as the tablet dissolves.
• In case of irritation, you can change the placement of the tablet on your gum.
• After 30 minutes, if there are still remnants of the Effentora tablet, you can swallow them with a glass of water.

If you use more Effentora than you should

• The most common adverse effects are drowsiness, dizziness, or discomfort. If you start to feel very dizzy or drowsy before the tablet has dissolved completely, rinse your mouth with water and spit out the remaining tablet immediately in the sink or toilet.
• A serious adverse effect of Effentora is slow and/or shallow breathing. This can occur if the dose of Effentora is too high or if you have taken too much Effentora. In severe cases, taking too much Effentora can lead to coma. If you feel very dizzy, very drowsy, or have slow or shallow breathing, seek immediate medical attention.

If you forget to use Effentora

If the breakthrough pain persists, you can take Effentora as directed by your doctor. If the breakthrough pain has disappeared, do not take Effentora until the next episode of breakthrough pain.

If you interrupt treatment with Effentora

You should stop Effentora when you no longer have any breakthrough pain. However, you should continue taking your usual opioid pain medication to treat persistent cancer pain, as directed by your doctor. When you stop treatment with Effentora, you may experience withdrawal symptoms similar to the possible adverse effects of Effentora. If you experience withdrawal symptoms or are concerned about pain relief, you should consult your doctor. Your doctor will assess whether you need medication to reduce or eliminate withdrawal symptoms.

If you have any other questions about using this medication, ask your doctor or pharmacist.

4. Possible side effects

Like all medications, this medication can cause side effects, although not everyone will experience them. If you notice any of them, inform your doctor.

Serious side effects

• The most serious side effects are shallow breathing, low blood pressure, and shock. Effentora, like other fentanyl-based products, can cause very serious breathing problems that can lead to death. If you feel very drowsy or have slow and/or shallow breathing, you or your caregiver should contact your doctor immediately and seek urgent help.

• Contact your doctor immediately if you experience a combination of the following symptoms
