1. What Instanyl is and what it is used for

Instanyl contains the active substance fentanyl and belongs to a group of strong painkillers called opioids. Opioids act by blocking the pain signals to the brain.

Instanyl acts very fast and is used for relieving breakthrough pain in adult cancer patients already treated with opioids for their usual pain. Breakthrough pain is an additional sudden pain that occurs despite you having taken your usual opioid pain relieving medicines.

2. What you need to know before you use Instanyl

Do not use Instanyl:

  • if you are hypersensitive (allergic) to fentanyl or any of the other ingredients of Instanyl;
  • 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 Instanyl, because it may increase the risk that breathing could become dangerously slow and/or shallow, or even stop.
  • if you suffer from short-term pain other than breakthrough pain.
  • if you have serious difficulties breathing or suffer from a serious obstructive lung disease;
  • if you have previously received facial radiotherapy;
  • if you suffer from recurrent episodes of nose bleeding.

Warnings and precautions

Talk to you doctor before using Instanyl, especially

  • if you suffer from a long-term obstructive lung disease, your breathing may be impaired by Instanyl;
  • if you have problems with your heart especially slow heart rate, low blood pressure or low blood volume;
  • if you have problems with your liver or kidneys;
  • if you have problems with your brain function, e.g. due to a brain tumour, a head injury or increased intracranial pressure;
  • if you take antidepressants or antipsychotics, please refer to the section Other medicines and Instanyl;
  • if you use other nasal spray products, e.g. for common cold or allergy.

If you experience difficulties breathing while being treated with Instanyl, it is important that you contact your doctor or hospital immediately.

Consult your doctor while using Instanyl, 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.
  • 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.

If you experience recurrent nose bleeding or nasal discomfort whilst being treated with Instanyl, you must contact your doctor, who will consider alternative treatment for your breakthrough pain.

If you think you are becoming dependent on Instanyl, it is important that you inform you doctor.

Children and adolescents

Instanyl should not be used in children and adolescents under 18 years of age.

Other medicines and Instanyl

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.

Instanyl may affect or be affected by other medicines.

Special care should be taken if you are treated with any of the following medicines:

  • Any medicines which might normally make you sleepy (have a sedative effect) such as sleeping pills, medicines to treat anxiety, antihistamines, or tranquillisers
  • Any medicines that might have an effect on the way in which your body breaks down Instanyl, such as
    • ritonavir, nelfinavir, amprenavir, and fosamprenavir (medicines that help control HIV infection)
    • CYP3A4 inhibitors such as ketoconazole, itraconazole, or fluconazole (used for treatment of fungal infections),
    • troleandomycin, clarithromycin, or erythromycin (medicines for treatment of bacterial infections),
    • aprepitant (used to treat severe nausea)
    • diltiazem and verapamil (medicines for treatment of high blood pressure or heart diseases)
  • Medicines called Monoamine Oxidase Inhibitors (MAOI) used for severe depression, even if you have been treated with one in the past 2 weeks
  • The risk of side effects increases if you are taking medicines such as certain antidepressants or antipsychotics. Instanyl 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 Instanyl is suitable for you.
  • Medicines called partial agonist/antagonists e.g. buprenorphine, nalbuphine and pentazocine (medicines for treatment of pain). You could experience symptoms of withdrawal syndrome (nausea, vomiting, diarrhoea, anxiety, chills, tremor, and sweating).
  • Other medicines taken via the nose, especially oxymetazoline, xylometazoline and similar medicines, which are used for relief of nose congestions.

Using Instanyl with food, drink or alcohol

Do not drink alcohol whilst being treated with Instanyl, as it can increase the risk of experiencing dangerous side effects.

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 taking any medicine.

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

Instanyl should not be used during childbirth because fentanyl may cause serious breathing problems in the new-born child.

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

Driving and using machines

You should not drive or use machinery whilst being treated with Instanyl. Instanyl can cause dizziness and drowsiness, which may affect your ability to drive or use machines.

3. How to use Instanyl

Always use this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

The dose of Instanyl is independent of your usual cancer pain treatment.

When you first start using Instanyl, your doctor will work with you to find the dose that will relieve your breakthrough pain.

The initial dose is one puff of 50 micrograms in one nostril each time you have an episode of breakthrough pain. During the determination of your right dose, your doctor may instruct you to change to a higher dose.

If your breakthrough pain is not relieved after 10 minutes, you may use only one puff more for this episode.

Generally you should wait 4 hours before treating another episode of breakthrough pain. On exceptional occasions where a new episode occurs earlier, you can use Instanyl to treat it but you must wait at least 2 hours before doing so. If you regularly have breakthrough pain episodes that are less than 4 hours apart, contact your doctor as your usual cancer pain treatment may have to be changed.

You can use Instanyl to treat up to four episodes of breakthrough pain per day.

If you experience more than four episodes of breakthrough pain per day, contact your doctor, as your usual cancer pain treatment may have to be changed.

Do not change the dose of Instanyl or your other pain medicines on your own. Change in dose must be done together with your doctor.

Instanyl is for nasal use.

Please read the Instruction for Use at the end of this leaflet to learn how to use Instanyl.

If you use more Instanyl than you should or if you think someone has accidentally used Instanyl

You should contact your doctor, hospital or emergency room for assessment of the risk and for advice if you have taken more Instanyl than you should.

Symptoms of overdose are:

Sleepiness, drowiness, dizziness, reduced body temperature, slow heart beat, difficulties coordinating arms and legs.

In serious cases taking too much Instanyl may cause coma, sedation, convulsions or severe breathing difficulties (very slow or shallow breathing).

If you feel any of the above symptoms you should seek immediate medical assistance.

Note to carers

If you see the person taking Instanyl suddenly acting slowly, having difficulties breathing or if you have difficulties waking the person up:

  • You should immediately call for emergency help;
  • While waiting for the emergency help, you must try to keep the person awake by talking to or gently shaking the person every now and then;
  • If the person has difficulty breathing, you should prompt the person to breathe in every 5-10 seconds;
  • If the person has stopped breathing, you should attempt to resuscitate her/him until emergency help arrives.

If you think someone has accidentally taken Instanyl, please seek immediate medical assistance. Try to keep the person awake until emergency help arrives.

If someone has accidentally taken Instanyl, they may have the same symptoms as described above for overdose.

If you forget to use Instanyl

If the breakthrough pain is still ongoing, you may take Instanyl as prescribed by your doctor. If the breakthrough pain has stopped, do not take Instanyl until the next episode of breakthrough pain occurs.

If you stop using Instanyl

You should discontinue Instanyl when you no longer have any breakthrough pain. You should however continue to take your usual pain relieving medicine to treat your cancer pain. Contact your doctor to confirm the correct dose of your usual medicine if you are not sure.

You may experience withdrawal symptoms similar to the possible side effects of Instanyl when discontinuing Instanyl. If you experience withdrawal symptoms, 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 product, ask your doctor or pharmacist.
