IMPORTANT:

  1. DO NOT USE FENTORA unless you are regularly using other opioid pain medicines around-the-clock for your constant cancer pain and your body is used to these medicines.
  2. Keep FENTORA in a safe place away from children. Accidental use by a child is a medical emergency and can result in death. If a child accidentally takes FENTORA, get emergency help right away.

Read the Medication Guide that comes with FENTORA before you start taking it and each time you get a new prescription. There may be new information. This Medication Guide does not take the place of talking to your doctor about your medical condition or your treatment. Share this important information with members of your household.

The most important information you should know about FENTORA is:

  1. FENTORA can cause life-threatening breathing problems which can lead to death:
    • If you are not regularly using other opioid pain medicines around-the-clock for your constant cancer pain and your body is not used to these medicines. This means that you are not opioid tolerant
    • If you do not use it exactly as prescribed by your doctor
  2. Your doctor will prescribe a starting dose of FENTORA that is different than other fentanyl containing medicines you may have been taking. Do not substitute FENTORA for other fentanyl medicines, including Actiq®, without talking with your doctor.
