1. What is Kaptic and what is it used for

Kaptic is a treatment for adults who are already taking regular, potent pain medicines (opioids)for their persistent cancer pain, but who need treatment for breakthrough pain. If you are not sure, consult your doctor.

Breakthrough pain is a type of pain that happens suddenly, even when you have taken or used your usual opioid medicine for your pain.

The active substance in Kaptic sublingual tablets is fentanyl. Fentanyl belongs to a group of strong pain medicines called opioids.

2. What you need to know before you take Kaptic

Do not take Kaptic

  • 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
  • If you are not regularly using a prescribed opioid medicine (e.g. codeine, fentanyl, hydromorphone, morphine, oxycodone, meperidine), 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 use Kaptic, as its use may increase the risk that your breathing becomes slower and/or shallower, and may even stop.
  • If you have short-term pain that is not breakthrough pain.

Warnings and precautions

Tell your doctor or pharmacist or nurse before you start taking Kaptic if you have or have had any of the following conditions, as your doctor will need to take them into account when prescribing your dose:

  • A head injury, as Kaptic may mask the extent of the damage
  • Breathing problems or severe myasthenia (a condition characterized by muscle weakness)
  • If you have heart problems, especially a slow heart rate
  • Low blood pressure
  • Liver or kidney disease, as you may need your doctor to adjust your dose with more caution
  • Brain tumor and/or increased 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 section “Other medicines and Kaptic”.
  • If you are taking pain medicines for nerve pain (gabapentin and pregabalin).

When you are taking Kaptic, tell your doctor or dentist that you are taking this medicine, if:

  • you are going to have an operation
  • 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.
  • 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 an indication of a potentially life-threatening condition called adrenal insufficiency, in which the adrenal glands do not produce enough hormones.
  • you have ever had adrenal insufficiency or a lack of sex hormones (androgen deficiency) with the use of opioids.
  • you have sleep-related breathing disorders: Kaptic may cause sleep-related breathing disorders such as sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low oxygen level in the blood). Symptoms may include pauses in breathing during sleep, waking up at night due to difficulty breathing, difficulty staying asleep, or excessive sleepiness during the day. If you or someone else notices these symptoms, contact your doctor. Your doctor may consider reducing the dose.
  • repeated use of Kaptic may lead to dependence and abuse that can cause a potentially life-threatening overdose. If you are concerned about becoming dependent on Kaptic, it is important that you consult your doctor.

Your doctor may need to monitor you more closely:

  • if you or a family member have ever had a history of alcohol, prescription drug, or illicit drug abuse (“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 illnesses.

Use in athletes

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

Other medicines and Kaptic

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

Some medicines may increase or decrease the effects of Kaptic. Consequently, if you start, change the dose, or stop treatment with the following medicines, tell your doctor, as they may need to adjust your dose of Kaptic.

The following medicines may increase the effects of Kaptic:

  • Certain types of antifungal medicines that contain substances such as ketoconazole or itraconazole (used to treat fungal infections)
  • Certain types of antibiotic medicines used to treat infections (called macrolides, which contain substances such as erythromycin)
  • Certain types of antiviral medicines called protease inhibitors, which contain, for example, ritonavir (used to treat viral infections).

The following medicines may reduce the effects of Kaptic:

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

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

Some examples of sedative medicines are:

  • other strong pain medicines(opioid-type medicines for pain and cough)
  • general anesthetics (used to put you to sleep during operations)
  • muscle relaxants
  • sleeping pills
  • medicines used to treat
    • depression
    • allergies
    • anxiety
    • psychosis
  • medicines that contain clonidine (used to treat high blood pressure)

However, if your doctor prescribes Kaptic and sedative medicines at the same time, the dose and duration of treatment should be limited by your doctor.

Tell your doctor about all sedative medicines you are taking and follow the recommended dose strictly as prescribed by your doctor. It may be useful to inform your family or friends about the signs and symptoms mentioned above. Talk to your doctor if you experience any of these symptoms.

The risk of side effects increases if you are taking medicines such as certain antidepressants or antipsychotics. Kaptic 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, diarrhea). Your doctor will tell you if Kaptic is suitable for you.

It is not recommended to use Kaptic at the same time as medicines called monoamine oxidase inhibitors (MAOIs), used to treat severe depression and Parkinson's disease. Tell your doctor if you have taken this type of medicine in the last two weeks.

Using Kaptic with food, drinks, and alcohol

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

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

Pregnancy and breastfeeding

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

Fentanyl can pass into breast milk and cause side effects in the breastfed baby. Do not use Kaptic if you are breastfeeding. You should not start breastfeeding until at least 5 days after the last dose of Kaptic.

Ask your doctor or pharmacist for advice before taking any medicine during pregnancy or breastfeeding.

Driving and using machines

Ask your doctor if you can drive or use machines while taking Kaptic. It is important that before driving or using machines, you see how this medicine affects you. Do not drive or use machines if you feel drowsy, dizzy, have blurred vision, or double vision, or have difficulty concentrating. Be especially careful at the start of treatment, after a dose increase, after a change in formulation, and/or when taking it with other medicines.

3. How to take Kaptic

Before taking Kaptic for the first time, your doctor will explain how you should take it to effectively treat your breakthrough pain.

Follow the instructions for taking this medicine exactly as your doctor has told you. If you are unsure, consult your doctor or pharmacist again.

YOU SHOULD ONLY USE THIS MEDICINE AS DIRECTED BY YOUR DOCTOR.Do not use it for anyone else, as it could cause serious health risks, especially in children.

Kaptic is a different type of medicine from other medicines you may have used to treat breakthrough pain. YOU SHOULD ALWAYS TAKE THE DOSE OF KAPTIC AS DIRECTED BY YOUR DOCTOR;this may be a different dose from the one you used with other pain medicines for breakthrough pain.

Starting treatment – Finding the right dose

For Kaptic treatment to be successful, your doctor will need to find the right dose for treating your breakthrough pain. Kaptic is available in a wide range of doses. You may need to try different doses of Kaptic during different episodes of pain before finding the right dose. Your doctor will help you with this and find the right dose for you.

If you do not get adequate pain relief with a dose, your doctor may tell you to take an additional dose to treat a breakthrough pain episode. DO NOT TAKE A SECOND DOSE UNLESS YOUR DOCTOR TELLS YOU TO,as you may experience an overdose.

Your doctor may advise you to take a dose made up of more than one tablet at the same time. ONLY DO THIS IF YOUR DOCTOR HAS TOLD YOU TO.

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

Continuing treatment – Once the right dose is established

Once you and your doctor have established a dose of Kaptic that controls your breakthrough pain, you should not take this dose more than four times a day. A DOSE OF KAPTIC MAY CONSIST OF MORE THAN ONE TABLET.

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

If you think the dose of Kaptic you are using does not control your breakthrough pain satisfactorily, tell your doctor, as you may need to have your dose adjusted.

Do not change your dose of Kaptic unless your doctor tells you to.

Taking the medicine

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 starts to work to relieve your pain.

When you have an episode of breakthrough pain, take the dose as directed by your doctor as follows:

  • If your mouth is dry, take a sip of water to moisten it. Spit or swallow the water.
  • Remove 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 (keep the remaining units in the blister pack together).
    • Peel back the edge of the foil by where the arrow indicates and carefully remove the tablet. Do not try to push the Kaptic sublingual tablets through the foil, as this will damage the tablets.
  • Place the tablet under your tongue as far back as you can and let it dissolve completely.
  • Kaptic will dissolve quickly under your tongue and be absorbed to provide relief from your pain. It is therefore important that you do not suck, chew, or swallow the tablet.
  • Do 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 tablets from your mouth
  • Tell your caregiver or another person what has happened
  • You should contact your doctor, pharmacist, or local hospital immediately and ask for advice
  • While waiting for the doctor, keep the person awake by talking to them or shaking them from time to time

Symptoms of an overdose include:

  • Extreme drowsiness
  • Slow, shallow breathing

If this happens, seek medical help immediately.

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

If you stop taking Kaptic

You should stop using Kaptic when you no longer have breakthrough pain. However, you should continue taking your usual opioid medicines for persistent cancer pain as recommended by your doctor. You may experience withdrawal symptoms similar to the possible side effects of Kaptic when you stop treatment with Kaptic. If you have withdrawal symptoms or are concerned about pain relief, consult your doctor, who will assess whether you need any medicine to reduce or prevent withdrawal symptoms.

If you have any further questions about the use of this medicine, ask your doctor or pharmacist.
