Instanyl – Fentanyl uses, dose and side effects

}

50 micrograms / dose, 100 micrograms / dose, 200 micrograms / dose nasal spray, fentanyl solution

1. What Instanyl is and what it is used for

Instant contains the active substance fentanyl which belongs to a group of strong painkillers called opioids. Opioids block the pain signals to the brain. Instant acts quickly and is used to relieve breakthrough pain in adult cancer patients who are already being treated with opioids for their common pain. Breakthrough pain is an additional sudden pain that occurs even if you have taken your usual painkiller opioid medications.

2. What you need to know before using Instanyl

Do not use Instanyl

  • if you are allergic to fentanyl or any of the other ingredients of this medicine (listed in section 6).
  • If you do not take it regularly every day for at least a week, use a prescription opioid medicine (eg codeine , fentanyl , hydromorphone, morphine, oxycodone, pethidine) to treat persistent pain. If you have not used such medicines, do not use Instanyl, as this may increase the risk of your breathing becoming dangerously slow and / or shallow, or even stopping.
  • if you are taking a medicine containing sodium oxybate.
  • if you have short-term pain, other than breakthrough pain.
  • if you have severe breathing problems or suffer from a serious obstructive pulmonary disease .
  • if you have previously received radiation treatment for your face.
  • if you have recurrent nosebleeds.

Warnings and cautions

Talk to your doctor or pharmacist before using Instant:

  • if you have a long-term obstructive pulmonary disease , as your breathing may be impaired by Instanyl.
  • if you have heart problems, especially slow heart rate, low blood pressure or low blood volume.
  • if you have liver or kidney problems.
  • if you have problems with brain function, e.g. due to a brain tumor, a head injury or increased pressure inside the head.
  • if you have ever had adrenal insufficiency or sex hormone deficiency (androgen deficiency) with opioid use.
  • if you or someone in your family has ever abused or been addicted to alcohol, prescription drugs or illegal drugs.
  • if you are a smoker.
  • if you have ever had problems with your mood (depression, anxiety or a personality disorder) or have been treated by a psychiatrist for other mental problems.
  • if you are taking antidepressants or antipsychotics (see also section “Other medicines and Instanyl”).
  • if you are taking medicines called partial agonists / antagonists, e.g. buprenorphine, nalbufine and pentazocine (painkillers), as you may have symptoms of withdrawal syndrome. See the section “ Other medicines and Instanyl ” for more information.
  • if you use other nasal sprays, e.g. for colds or allergies .

If you experience difficulty breathing with Instant, it is very important that you contact your doctor or hospital immediately.

Talk to your doctor when using Instant about:

  • you feel pain or become more sensitive to pain (hyperalgesia) and it does not help with a higher dose of your medicine according to the doctor’s prescription .
  • You get a combination of the following symptoms: nausea, vomiting, anorexia , fatigue, weakness, dizziness and low blood pressure . When they occur at the same time, these symptoms can be a sign of so-called adrenal insufficiency, a condition which means that the adrenal glands do not produce enough hormones and which can be life-threatening.

If you experience recurrent nosebleeds or nasal discomfort during treatment with Instant, you must contact a doctor who will consider any alternative treatment for your breakthrough pain.

If you think you are becoming addicted to Instant, it is important that you tell your doctor.

  • all drugs that can affect the way your body breaks down Instanyl, e.g.
    • ritonavir, nelfinavir, amprenavir, and fosamprenavir (medicines that help control HIV – infection )
    • or CYP3A4 inhibitors such as ketoconazole , itraconazole or fluconazole (used to treat fungal infections)

3. How to use Instanyl

Always take this medicine exactly as your doctor has told you. Ask your doctor or pharmacist if you are unsure.

Dos en Instant is independent of your usual treatment for cancer pain.

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

The starting dose is a 50 microgram puff in a nostril each time you experience an episode of breakthrough pain. During the time the correct dose is being determined, your doctor may ask you to switch to a higher dose.

If your breakthrough pain is not relieved after 10 minutes, just take one more puff during this episode.

You should usually wait 4 hours before treating another episode of breakthrough pain. In exceptional cases, when a new episode occurs earlier, you can use Instant to treat it, but you must wait at least 2 hours before doing so. If you regularly have episodes of breakthrough pain at intervals of less than 4 hours, consult your doctor as your usual treatment for cancer pain may need to be changed.

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

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

You should check the boxes in the brochure on the top of the outer, child-resistant box to keep track of how many doses of Instant you have used.

Do not change the dose of Instant or your other pain medicines. Dose adjustment must be made together with the doctor.

Instant should be used in the nose.
