1. What is Vellofent and what is it used for

Vellofent contains the active substance fentanyl, which belongs to a group of strong painkillers called opioids. Vellofent is used to treat breakthrough pain in adult patients with cancer who are already taking other painkillers for their persistent (ongoing) cancer pain. Breakthrough pain is a type of pain that occurs suddenly and is not controlled by your regular pain medicine.

2. Important information before taking Vellofent

When not to take Vellofent

• 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 lung disease;
• if you are currently taking monoamine oxidase inhibitors (MAOIs) for severe depression (or have taken them in the last 2 weeks);
• if you have not been taking a strong opioid painkiller (such as codeine, fentanyl, hydromorphone, morphine, oxycodone, or pethidine) regularly for at least one week to control your persistent pain, as prescribed by your doctor. If you have not been taking these medicines, you must not take Vellofent,

as it may increase the risk of serious or life-threatening breathing problems. If you have any of these conditions, do not take Vellofent.

• if you have short-term pain other than breakthrough pain;
• if you are currently taking medicines containing sodium hydroxymethanesulfonate.

Warnings and precautions

Vellofent contains the active substance in an amount that can be fatal to a child, and therefore all tablets should always be kept out of sight and out of reach of children and persons for whom they have not been prescribed.

Tablets should be stored in a closed place and not stored after removal from the blister pack. The medicine should be stored in a safe and protected place where others cannot access it (for more information, see section 5, "How to store Vellofent"). You should talk to your doctor or pharmacist before starting to take Vellofent. Before starting treatment, the patient should tell the doctor if any of the following situations have occurred or are occurring, which the doctor should consider when prescribing the dose of Vellofent:

• the painkiller currently being taken for persistent (24 hours a day) cancer pain is not yet working satisfactorily;
• any condition that makes breathing difficult (such as asthma, wheezing, or shortness of breath);
• head injury;
• heart problems, especially slow heart rate, irregular heartbeat, low blood volume, or low blood pressure;
• liver or kidney problems, as these organs are involved in the elimination (conversion and excretion) of the taken medicine;
• the patient is taking antidepressant or antipsychotic medicines, see "Other medicines and Vellofent".

You should consult your doctor if, while taking Vellofent, you experience:

• pain or increased sensitivity to pain (hyperalgesia) that does not respond to a higher dose of painkiller prescribed by your doctor;
• several of the following symptoms: nausea, vomiting, loss of appetite, fatigue, weakness, dizziness, and low blood pressure; these symptoms may be a sign of a potentially life-threatening condition called adrenal insufficiency, in which the adrenal glands do not produce enough hormones;
• the patient has ever had adrenal insufficiency or a lack of sex hormones (androgen deficiency) while taking opioids.

Long-term use and tolerance This medicine contains fentanyl, which is an opioid. Repeated use of opioid painkillers can lead to decreased effectiveness of the medicine (the patient becomes accustomed to it, which is known as tolerance to the medicine). During treatment with Vellofent, the patient's sensitivity to pain may also increase. This phenomenon is known as hyperalgesia. Increasing the dose of Vellofent may temporarily reduce the intensity of the pain, but it can also be harmful. If the patient notices a decrease in the effectiveness of the medicine, they should consult their doctor. The doctor will decide whether it is better for the patient to increase the dose or gradually reduce the use of Vellofent. Dependence and addictive use This medicine contains fentanyl, which is an opioid. It can cause dependence and (or) addiction. Repeated use of Vellofent can also lead to dependence, abuse, and addictive use, which can result in life-threatening overdose. The risk of these side effects may increase with increasing dose and duration of use. Dependence or addictive use can cause the patient to feel a loss of control over how much medicine to use or how often to take it. The patient may feel the need to continue using the medicine, even if it does not help alleviate their pain.

• The patient or someone in their family has ever abused or been dependent on alcohol, prescription drugs, or illegal substances ("addiction");
• The patient smokes tobacco;
• The patient has ever had mood disorders (depression, anxiety disorders, or personality disorders) or has been treated by a psychiatrist for other mental illnesses.

If, while taking Vellofent, the patient experiences any of the following symptoms, it may indicate dependence or addictive use.

• The patient must take the medicine for a longer period than prescribed by the doctor.
• The patient must take a higher dose than prescribed.
• The patient uses the medicine for reasons other than those for which the doctor prescribed it, such as "to calm down" or "to fall asleep".
• The patient has made several unsuccessful attempts to stop or control the use of the medicine.
• After stopping the medicine, the patient feels unwell (e.g., nausea, vomiting, diarrhea, anxiety, shivering, tremors, and excessive sweating), and their condition improves when they take the medicine again ("withdrawal effect").

If the patient notices any of these symptoms, they should discuss the best treatment strategy with their doctor, including determining when it is appropriate to stop treatment and how to safely stop treatment. Sleep apnea Vellofent may cause sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low oxygen levels in the blood). Symptoms may include pauses in breathing during sleep, nighttime awakenings due to shortness of breath, difficulty staying asleep, or excessive daytime sleepiness. If the patient or another person notices these symptoms, they should contact their doctor. The doctor may consider reducing the dose.

Children and adolescents

Vellofent is not indicated for use in children and adolescents under 18 years of age.

Other medicines and Vellofent

You should tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take, especially the following groups of medicines:

• monoamine oxidase inhibitors (MAOIs) used in severe depression, see above "When not to take Vellofent". You should tell your doctor if you have taken such a medicine in the last 2 weeks,
• sleeping medicines, anxiolytics, antihistamines, antipsychotics, some muscle relaxants, or any other medicines that cause drowsiness (have a sedative effect), as well as some painkillers used in neuropathic pain (gabapentin and pregabalin),
• any medicines that may affect the action of Vellofent (by affecting its elimination in the body), such as:
• medicines used to treat HIV infection (such as ritonavir, indinavir, nelfinavir, saquinavir),
• medicines used to treat fungal infections (such as ketoconazole, itraconazole, or fluconazole),
• medicines used to treat bacterial infections (such as clarithromycin, erythromycin, telithromycin), including anti-tuberculosis medicines (such as rifabutin, rifampicin),
• medicines used to treat severe vomiting (such as aprepitant, dronabinol),
• medicines used to treat high blood pressure or heart disease (such as diltiazem or verapamil),
• antidepressant medicines (such as fluoxetine or St. John's wort),
• medicines for heartburn and indigestion (such as cimetidine),
• sleeping or sedative medicines (such as phenobarbital),
• medicines used to control seizures and epileptic fits (such as carbamazepine, phenytoin, oxcarbazepine),
• antiviral medicines (such as efavirenz, nevirapine),
• anti-inflammatory or immunosuppressive medicines (such as glucocorticosteroids),
• medicines used to treat diabetes (such as pioglitazone),
• psychostimulant medicines (such as modafinil),
• certain types of strong painkillers called partial agonist/antagonists, e.g., buprenorphine, nalbuphine, and pentazocine (medicines used to treat pain). When taking these medicines, withdrawal symptoms may occur (nausea, vomiting, diarrhea, anxiety, shivering, tremors, and sweating). These medicines may reduce or eliminate the effect of Vellofent,
• the risk of side effects increases if the patient takes such medicines as certain antidepressants or antipsychotics. Vellofent may interact with these medicines, and the patient 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 increased reflexes, muscle stiffness, lack of coordination, and (or) gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). The doctor will tell the patient if Vellofent is suitable for them,
• concomitant use of Vellofent and sedative medicines, such as benzodiazepines or related medicines, increases the risk of sedation, breathing difficulties (respiratory depression), coma, and can be life-threatening. Therefore, concomitant use of Vellofent and sedative medicines should only be considered when other treatment options are not possible. If the doctor prescribes Vellofent concomitantly with sedative medicines, they should limit the dose and duration of concomitant treatment. You should inform your doctor about all sedative medicines you are taking and strictly follow the doctor's instructions. It may be helpful to inform friends or relatives to be aware of the above symptoms. If such symptoms occur, you should contact your doctor,
• concomitant use of medicines containing sodium hydroxymethanesulfonate and fentanyl is contraindicated (see "When not to take Vellofent"). Treatment with sodium hydroxymethanesulfonate should be discontinued before starting treatment with Vellofent.

Vellofent with food, drink, and alcohol

• Vellofent can be taken before or after a meal, but not during a meal. You can take a sip of water before taking Vellofent to moisten your mouth, but do not drink or eat anything while taking the medicine.
• Do not drink grapefruit juice while taking Vellofent, as it may affect the elimination of the medicine from the body.
• Do not drink alcohol while taking Vellofent, as it may increase the risk of serious side effects.

Pregnancy and breastfeeding

If you are pregnant, think you may be pregnant, or plan to become pregnant, you should consult your doctor or pharmacist before taking this medicine. You should not take Vellofent during pregnancy without consulting your doctor. You should not take Vellofent during childbirth, as fentanyl may cause respiratory depression and withdrawal syndrome in the fetus or newborn. Fentanyl may pass into breast milk and cause side effects in the breastfed infant. You should not take Vellofent while breastfeeding. Breastfeeding should not be started until at least 5 days after the last dose of Vellofent.

Driving and using machines

You should talk to your doctor about whether it is safe for you to drive or operate machinery after taking Vellofent. You should not drive or operate machinery if you experience drowsiness or dizziness, blurred or double vision, or difficulty concentrating. It is essential to know how your body reacts to Vellofent before deciding to drive or operate machinery.

Vellofent contains sodium

The medicine contains less than 1 mmol of sodium (23 mg) per tablet, which means it is considered "sodium-free".

3. How to take Vellofent

Before starting and regularly during treatment, your doctor will also discuss with you what to expect from Vellofent, when and for how long to take it, when to see a doctor, and when to stop taking the medicine (see also section 2). The tablet should be placed under the tongue (sublingual administration). This medicine should always be taken under the supervision of a doctor or specialist and in accordance with their instructions. If you have any doubts, you should consult your doctor or pharmacist. If your doctor has prescribed a change from your current painkiller to Vellofent, you should not continue to take the previous painkiller containing fentanyl for breakthrough pain. You should dispose of the previous painkiller containing fentanyl. However, during treatment with Vellofent, you should continue to take your opioid painkiller for persistent (24 hours a day) cancer pain.

Initial phase - Finding the right dose

To be effective, your doctor must determine the right dose of Vellofent to use for a single episode of breakthrough pain. Vellofent sublingual tablets are available in different strengths. To determine the right dose, you, in collaboration with your doctor, may take different strengths of Vellofent sublingual tablets in several episodes of breakthrough pain. Your doctor will help you determine the right strength of the tablet for you. If you do not experience the desired pain relief after taking one tablet, your doctor may instruct you to take two tablets to treat an episode of breakthrough pain. You should not take a second tablet without your doctor's instruction, as this may cause overdose. Your doctor will advise you on which strength of tablet to use. You should always take the dose of Vellofent prescribed by your doctor - this dose may be different from the dose of other painkillers you are taking for breakthrough pain.

Maintenance phase - Once the right dose is determined

After determining the dose of Vellofent that controls your breakthrough pain, you should not take it more than four times a day. The dose of Vellofent may be more than one tablet. If you think the dose of Vellofent you are taking is not enough to control your breakthrough pain, you should tell your doctor, as it may need to be adjusted. You should not change the dose of Vellofent without consulting your doctor.

How to take the medicine

Vellofent should be taken sublingually. This means that the tablet should be placed under the tongue, where it will dissolve quickly, allowing fentanyl to be absorbed through the mucous membrane of the mouth. When you experience an episode of breakthrough pain, you should take the dose prescribed by your doctor, following the instructions below:

• If you feel dryness in your mouth, you can moisten it with a small amount of water. You can spit out or swallow the water.
• Take the tablet(s) out of the packaging just before taking the medicine.
• Remove the foil layer from the blister pack, as described on the blister pack, and gently remove the tablet. Do not push the sublingual tablet of Vellofent through the foil.
• Place the tablet under your tongue as far back as possible and allow it to dissolve completely.
• Vellofent will dissolve quickly under your tongue and be absorbed to provide pain relief. Therefore, it is essential not to suck, chew, or swallow the tablet.
• After 30 minutes - if there are any remaining undissolved pieces of the tablet - you can swallow them.
• Do not drink or eat anything until the tablet has completely dissolved under your tongue.

What to do if you take more Vellofent than you should

You should:

• remove any remaining tablet from your mouth,
• inform your caregiver or another person about the incident,
• the patient or caregiver should immediately contact a doctor, pharmacist, or the emergency department of the nearest hospital for advice on what to do next.

Symptoms of overdose include: changes in mental status, loss of consciousness, increased drowsiness, slowed breathing. If these symptoms occur, immediate medical attention is needed. Overdose can also cause brain disorders called toxic leukoencephalopathy. Information for caregivers While waiting for the doctor to arrive:

• do not let the patient fall asleep - talk to them and shake them from time to time,
• make sure the patient has a clear airway and is breathing. If the patient suspects that someone else has accidentally taken Vellofent, they should immediately call for medical help.

If you forget to take Vellofent

Do not take a double dose to make up for a forgotten tablet.

Stopping Vellofent

You should stop taking Vellofent when you no longer experience breakthrough pain. However, you should continue to take your usual opioid painkillers to control your persistent cancer pain, as prescribed by your doctor. After stopping Vellofent, you may experience withdrawal symptoms similar to potential side effects associated with Vellofent. If you experience withdrawal symptoms or have concerns about pain relief, you should contact your doctor. Your doctor will assess whether it is necessary to administer medicines to limit or eliminate withdrawal symptoms. If you have any further questions about taking this medicine, you should consult your doctor or pharmacist.
