The active substance of Effentora is fentanyl citrate. Effentora 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) cancer pain.
Breakthrough pain is additional, sudden pain that occurs in spite of you having taken your usual opioid pain-relieving medicines.
- If you are not regularly using a prescribed opioid medicine (e.g codeine, fentanyl, hydromorphone, morphine, oxycodone, pethidine), every day on a regular schedule, for at least a week, to control your persistent pain. If you have not been using these medicines you must not use Effentora, because it may increase the risk that breathing could become dangerously slow and/or shallow, or even stop.
- If you are allergic to fentanyl or any of the other ingredients of this medicine (listed in section 6).
- If you suffer from severe breathing problems or severe obstructive lung conditions.
- If you suffer from short-term pain other than breakthrough pain
Keep using the opioid pain medicine you take for your persistent (around-the-clock) cancer pain during your Effentora treatment.
Whilst you are being treated with Effentora, do not use other fentanyl treatments previously prescribed for your breakthrough pain. If you still have some of these fentanyl treatments at home, contact your pharmacist to check how to dispose of them.
Talk to your doctor or pharmacist BEFORE using Effentora if:
- Your other opioid pain medicine taken for your persistent (around-the-clock) cancer pain is not stabilised 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 an 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 are over 65 years old - you may need a lower dose and any dose increase will be reviewed very carefully by your doctor.
- You have problems with your heart especially slow heart rate
- You use benzodiazepines (see section 2 under “Other medicines and Effentora”). Using benzodiazepines can increase the chances of getting serious side effects including death
- You use antidepressants or antipsychotics, (selective serotonin reuptake inhibitors [SSRIs], serotonin norepinephrine reuptake inhibitors [SNRIs], monoamine oxidase (MAO) inhibitors; see section 2 under “Do not use Effentora” and “Other medicines and Effentora”). The use of these medicines with Effentora can lead to a serotonin syndrome a potentially life-threatening condition (see section 2 under “Other medicines and Effentora”).
- You experience a combination of the following symptoms: nausea, vomiting, anorexia, fatigue, weakness, dizziness and low blood pressure. Together these symptoms may be a sign of a potentially life-threatening condition called adrenal insufficiency, a condition in which the adrenal glands do not produce enough hormones.
- You have ever developed adrenal insufficiency or lack of sex hormones (androgen deficiency) with opioid use (see section 4 under “Serious side effects”).
- You have a history of alcoholism or any drug abuse or dependence.
- You drink alcohol; please refer to section Effentora with food, drink and alcohol.
Consult your doctor WHILE using Effentora if:
- You experience pain or increased sensitivity to pain (hyperalgesia) which does not respond to a higher dosage of your medicine as prescribed by your doctor.
Seek URGENT medical advice if:
- You experience symptoms such as difficulty in breathing or dizziness, swelling of the tongue, lip or throat while using Effentora. These might be early symptoms of a serious allergic reaction (anaphylaxis, hypersensitivity; see section 4 under “Serious side effects”)
If you think someone has accidentally taken Effentora please seek immediate medical assistance. Try to keep the person awake until emergency help arrives.
If someone has accidentally taken Effentora, they may have the same side effects as described in the section 3 “If you use more Effentora than you should”.
Do not give this medicine to children and adolescents below18 years of age.
Tell your doctor or pharmacist before starting Effentora if you are taking or have recently taken or might take any of the following medicines:
- Concomitant use of Effentora and sedative medicines such as benzodiazepines or related drugs increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible.
However if your doctor does prescribe Effentora together with sedative medicines the dose and duration of concomitant treatment should be limited by your doctor.
Please 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 tranquillisers) and follow your doctor’s dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms.
- Some muscle relaxants - such as baclofen, diazepam (see also section “Warnings and precautions”.
- Any medicines that might have an effect on the way in which your body breaks down Effentora, such as ritonavir, nelfinavir, amprenavir, and fosamprenavir (medicines that help control HIV infection) or other so-called CYP3A4 inhibitors such as ketoconazole, itraconazole, or fluconazole (used for treatment of fungal infections), troleandomycine, clarithromycine, or erythromycine (medicines for treatment of bacterial infections), aprepitant (used for severe nausea) and diltiazem and verapamil (medicines for treatment of high blood pressure or heart diseases).
- Medicines called monoamine-oxidase (MAO) inhibitors (used for severe depression) or have done so in the past 2 weeks.
- Certain type of strong pain killers, calledpartial agonist/antagonists e.g. buprenorphine, nalbuphine and pentazocine (medicines for treatment of pain). You could experience symptoms of withdrawal syndrom (nausea, vomiting, diarrhoea, anxiety, chills, tremor, and sweating) while using these medicines.
- 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 mental status changes (e.g. agitation, hallucinations, coma), and other effects such as body temperature above 38°C, increase in heart rate, unstable blood pressure, and exaggeration of reflexes, muscular rigidity, lack of coordination and/or gastrointestinal symptoms (e.g nausea, vomiting, diarrhoea). Your doctor will tell you whether Effentora is suitable for you.
Tell your doctor or pharmacist if you are taking or have recently taken or might take any other medicines.
- Effentora may be used before or after, but not during, meals. You may drink some water before using Effentora to help moisten your mouth, but you should not drink or eat anything while taking the medicine.
- You should not drink grapefruit juice while using Effentora because it may affect the way your body breaks down Effentora.
- Do not drink alcohol while using Effentora. It can increase the risk of experiencing serious side effects including death.
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.
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 also a risk of the new-born child having withdrawal symptoms which might be life-threatening if not recognized and treated by a doctor.
You should not use Effentora during childbirth because fentanyl may cause respiratory depression in the new-born child.
Fentanyl can get into breast milk and may cause side effects in the breast-fed infant. 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.
You should discuss with your doctor whether it is safe for you to drive, or operate machinery after taking Effentora. Do not drive or operate machinery if you: are feeling sleepy or dizzy; have blurred or double vision; or have difficulty in concentrating. It is important you know how you react to Effentora before driving or operating machinery.
Each tablet of Effentora 100 micrograms contains 10 mg of sodium. Each tablet of Effentora 200 micrograms, Effentora 400 micrograms, Effentora 600 micrograms and Effentora 800 micrograms contains 20 mg of sodium. You should take this into consideration if you are on a controlled sodium diet and seek advice from your doctor.
Always use this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
When you first start using Effentora, your doctor will work with you to find the dose that will relieve your breakthrough pain. It is very important that you use Effentora 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 is not relieved after 30 minutes, use only 1 more tablet of Effentora during the titration period.
Once the right dose has been determined with your doctor, use 1 tablet for an episode of breakthrough pain as a general rule. In the further course of treatment your requirement for analgesic therapy may change. Higher doses may be necessary. If your breakthrough pain is not relieved after 30 minutes, use only 1 more tablet of Effentora during this dose-readjustment period.
Contact your doctor if your right dose of Effentora does not relieve your breakthrough pain. Your doctor will decide if your dose needs to be changed.
Wait at least 4 hours before treating another episode of breakthrough pain with Effentora.
You must let your doctor know immediately if you are using Effentora more than four times per day, as a change may be required to your treatment regimen. Your doctor may change the treatmentfor your persistent pain; when your persistent pain is controlled again, your doctor may need to change the dose of Effentora. If your doctor suspects Effentora-related increased sensitivity to pain (hyperalgesia), a reduction of your Effentora dose may be considered (see section 2 under “Warnings and precautions”). For the most effective relief, let your doctor know about your pain and how Effentora is working for you, so that the dose can be changed if needed.
Do not change doses of Effentora or your other pain medicines on your own. Any change in dosage must be prescribed and monitored by your doctor.
If you are not sure about the right dose, or if you have questions about taking this medicine, you should contact your doctor.
Effentora buccal tablets are for oromucosal 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.
- Open the blister only when you are ready to use the tablet. The tablet must be used immediately once removed from the blister.
- Separate one of the blister units from the blister card by tearing apart at the perforations.
- Bend the blister unit along the line where indicated.
- Peel the blister backing to expose the tablet. Do NOT attempt to push the tablet through the blister, because this can damage the tablet.
- Remove the tablet from the blister unit and immediately place the entire tablet near a molar tooth between the gum and the cheek (as shown in the picture). Sometimes, your doctor may tell you to place the tablet under your tongue instead.
- Do not attempt to crush or split the tablet.
- Do not bite, suck, chew, or swallow the tablet, as this will result in less pain relief than when taken as directed.
- The tablet should be left between the cheek and gum until dissolved, which usually takes approximately 14 to 25 minutes.
- You may feel a gentle bubbling sensation between your cheek and gum as the tablet dissolves.
- In case of irritation, you may change the placement of the tablet on the gum.
- After 30 minutes, if pieces of the tablet remain, they may be swallowed with a glass of water.
- The most common side effects are feeling sleepy, sick or dizzy. If you begin to feel very dizzy, or very sleepy before the tablet is completely dissolved, rinse your mouth with water and spit the remaining pieces of the tablet into a sink or toilet right away.
- A serious side effect of Effentora is slow and/or shallow breathing. This can occur if your dose of Effentora is too high or if you take too much Effentora. If this occurs, please seek immediate medical assistance.
If the breakthrough pain is still ongoing, you may take Effentora as prescribed by your physician. If the breakthrough pain has stopped, do not take Effentora until the next breakthrough pain episode.
You should discontinue Effentora 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 Effentora when discontinuing Effentora. 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.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
Like all medicines, this medicine can cause side effects, although not everybody gets them. If you notice any of these, contact your doctor.
- The most serious side effects are shallow breathing, low blood pressure and shock. Effentora like other fentanyl products can cause very severe breathing problems which can lead to death. If you become very sleepy or have slow and/or shallow breathing, you or your carer should contact your doctor immediately and call for emergency help.
