6. Contents of the pack and additional information

Kaptic is a treatment for adultswho are already regularly taking powerful pain medications (opioids)for their persistent cancer pain, but require treatment for breakthrough pain. If unsure, consult with 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 Kaptic sublingual tablets is fentanil. Fentanil belongs to a group of powerful pain medications called opioids.

Do not take Kaptic

• 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 taking a prescribed opioid medication (e.g., codeine, fentanyl, hydromorphone, morphine, oxycodone, meperidine) every day at the same time, for at least a week, to control persistent pain. If you have not been taking these medications, do not use Kaptic, as its use may increase the risk of your breathing becoming slower and/or shallower, and even stopping.
• If you have short-term pain other than breakthrough pain.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to take Kaptic if you have or have had any of the conditions listed below, as your doctor will need to take this into account when prescribing your dose:

• Head injury, as Kaptic may mask the extent of the damage
• Respiratory problems or myasthenia gravis (a condition characterized by muscle weakness)
• Heart problems, especially low heart rate
• Low blood pressure
• Liver or kidney disease, as your doctor may need to adjust the dose with more caution
• Brain tumor and/or elevated intracranial pressure (increase in brain pressure causing 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 “Other medications and Kaptic”.
• If you are taking pain medications for neuropathic pain (gabapentin and pregabalin).

When taking Kaptic, 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.
• You have ever experienced adrenal insufficiency or hormone deficiency (androgen deficiency) with the use of opioids.
• You experience sleep-related respiratory problems: Kaptic may cause sleep-related respiratory problems such as 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, nocturnal awakening due to difficulty breathing, difficulty maintaining sleep, or excessive daytime somnolence. If you or someone else observes these symptoms, contact your doctor. Your doctor may consider reducing the dose.
• The repeated use of Kaptic may lead to dependence and abuse that can cause a potentially fatal overdose. If you are concerned about the possibility of becoming dependent on Kaptic, it is essential to consult your doctor.

Your doctor may need to monitor you more closely:

• If you or a family member have ever experienced abuse or dependence on alcohol, prescription medications, or drugs (“addiction”).
• If you are a smoker.
• If you have ever experienced mood-related problems (depression, anxiety, or personality disorder) or have been treated by a psychiatrist for other mental health conditions.

Use in athletes

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

Other medications and Kaptic

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

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

The following medications may increase the effects of Kaptic:

• 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 infections caused by viruses).

The following medications may reduce the effects of Kaptic:

• Rifampicin or rifabutin (medications used to treat bacterial infections)
• Carbamazepine, phenytoin, or phenobarbital (medications used to treat seizures)
• Herbal medications containing St. John's Wort (Hypericum perforatum)
• Determined types of potent pain medications, called partial agonist/antagonists, such as buprenorphine, nalbuphine, and pentazocine (pain medications). You may experience withdrawal symptoms (nausea, vomiting, diarrhea, anxiety, chills, tremors, and sweating) while using these medications.

Kaptic may increase the effect of medications that make you feel sleepy, so the simultaneous use increases the risk of drowsiness, difficulty breathing (respiratory depression), coma, and may put your life at risk. Therefore, simultaneous use should only be considered when there are no other possible treatment alternatives.

Examples of sedative medications include:

• Otherpotent pain medications(opioid pain medications, for pain and cough)
• General anesthetics (used to put you to sleep during surgery)
• Muscle relaxants
• Sleeping pills
• Medications used to treat
• • depression
  • allergies
  • anxiety
  • psychosis
• Medications containing clonidine (used to treat high blood pressure)

However, if your doctor prescribes Kaptic and sedative medications simultaneously, the dose and duration of treatment should be limited by your doctor.

Inform your doctor of all sedative medications you are taking and strictly follow the recommended dose by your doctor. It may be helpful to inform your family or friends of the mentioned symptoms. Talk to your doctor if you experience any of these symptoms.

The risk of adverse effects increases if you are taking medications such as certain antidepressants or antipsychotics. Kaptic may interact with these medications, and you may experience changes in mental state (e.g., agitation, hallucinations, coma) and other effects such as high body temperature, 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 Kaptic is suitable for you.

It is not recommended to use Kaptic with medications called monoamine oxidase inhibitors (MAOIs), 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.

Use of Kaptic with food, drinks, and alcohol

Kaptic 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 Kaptic, as it may increase the adverse effects of Kaptic.

Pregnancy and breastfeeding

You should not take Kaptic during pregnancy unless your doctor has explicitly told you to.

Fentanyl may pass into the mother's bloodstream and cause adverse effects in the infant. Do not use Kaptic if you are breastfeeding. You should not initiate breastfeeding until at least 5 days have passed since your last dose of Kaptic.

Consult your doctor or pharmacist before using any medication during pregnancy or breastfeeding.

Driving and operating machinery

Ask your doctor if you can drive or operate machinery during treatment with Kaptic. It is essential to observe how this medication affects you before driving or operating machinery. Do not drive or operate machinery if you feel drowsy, dizzy, have blurred vision, or experience difficulty concentrating. Be especially careful at the start of treatment, after increasing the dose, after changing the formulation, and/or when taking it with other medications.

Before taking Kaptic for the first time, your doctor will explain how to take it to effectively manage your pain episodes.

Follow exactly the administration instructions for this medication as indicated by your doctor. If in doubt, consult your doctor or pharmacist again.

YOU should only use this medication according to your doctor's instructions. Do not use it on anyone else, as it could cause SERIOUS health risks, especially in children.

Kaptic is a type of medication different from others you may have used to treat breakthrough pain.You must always take the dose of Kaptic as indicated by your doctor;this may be a different dose from what you have used with other pain medications.

Starting treatment – Establishing the most suitable dose

To ensure successful treatment with Kaptic, your doctor will need to identify the most suitable dose for your breakthrough pain treatment. Kaptic is available in a wide range of doses. You may need to try different doses of Kaptic during different pain episodes before finding the most suitable dose. Your doctor will help you with this task and find the most suitable dose for you.

If you do not get adequate pain relief with a dose, your doctor may instruct you to take an additional dose to treat a breakthrough pain episode. Do not take a second doseunless your doctor instructs you to do so,as you may experience an overdose.

Your doctor may advise you to take a dose composed of more than one tablet at the same time.Do this only if your doctor has instructed you to do so.

After taking the last dose, wait at least two hours before treating another breakthrough pain episode with Kaptic.

Continuing treatment – Once the most suitable dose has been established

Once you and your doctor have established a Kaptic dose that controls your pain episodes, you should not take this dose more than four times a day.A Kaptic dose may consist of more than one tablet.

After taking the last dose, wait at least two hours before treating another breakthrough pain episode with Kaptic.

If you believe the Kaptic dose you are using does not adequately control your pain episodes, inform your doctor, as you may need to adjust the dose.

You should not change your Kaptic dose unless your doctor instructs you to do so.

Medication intake

Kaptic 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 begins to act to relieve pain.

When you have a breakthrough pain episode, take the dose indicated by your doctor as follows:

• If your mouth is dry, take a sip of water to moisten it. Spit out or swallow the water.
• Remove the (the) tablet(s) from the blister pack immediately before use as follows:
• • Separate one of the units from the blister pack by tearing along the perforation line (keep the remaining units of the blister pack together).
  • Peel the edge of the sheet where the arrow indicates and carefully remove the tablet. Do not try to press the sublingual Kaptic tablets through the top sheet, as this will damage the tablets.
• Place the tablet under your tongue as far back as possible, and let it dissolve completely.
• Kaptic will dissolve quickly under your tongue and be absorbed to provide you with pain relief. Therefore, it is essential not to suck, chew, or swallow the tablet.
• You should not drink or eat anything until the tablet has dissolved completely under your tongue.

If you take more Kaptic than you should

• Remove any remaining tablet from your mouth
• Tell your caregiver or another person what has happened
• You must contact your doctor, pharmacist, or local hospital immediately and ask for instructions
• While waiting for the doctor, keep the person awake by talking to them or shaking them occasionally

The symptoms of an overdose include:

• Extreme drowsiness
• Slow, shallow breathing

Seek immediate medical assistance if this occurs.

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicological Information Service, phone: 91 562 04 20, indicating the medication and the amount ingested.

If you interrupt treatment with Kaptic

You should stop using Kaptic when you no longer have breakthrough pain. 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 possible side effects of Kaptic when you interrupt treatment with Kaptic. If you experience withdrawal symptoms or are concerned about pain relief, consult your doctor, who will evaluate whether you need any medication to reduce or suppress withdrawal symptoms.

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

Like all medications, Kaptic may cause side effects, although not everyone will experience them.

If you start to feel unusual or extreme drowsiness or if your breathing becomes shallow and slow, you or your caregiver should contact your doctor or local hospital for emergency assistance (see also section 3 “If you take more Kaptic than you should”).
