Who should not take Fentora?

You shouldn't take Fentora (fentanyl), a prescription pill for breakthrough pain in cancer patients, if you aren't already on around-the-clock opioid painkillers. The drug is not safe unless you've built up a tolerance for opioids, so doctors don't prescribe it unless a patient has been taking an opioid painkiller, such as morphine, hydromorphone or oxymorphone, daily for at least a week. In fact, Fentora can cause a potentially fatal slowdown of breathing if it's used by anyone who hasn't built up a tolerance to these kinds of drugs. Fentora should not be used for treating headaches, backaches or post-surgical pain.

You shouldn't take Fentora if you're allergic to fentanyl or any other ingredients of the drug. Children shouldn't take Fentora, because even a fragment of this drug could cause serious harm or even death.
