What foods and alcohol interact with Fentora?

Fentora (fentanyl) can interact with a long list of drugs and supplements. If you are prescribed Fentora as a rescue medicine for treating breakthrough cancer pain, it is critical that you tell your doctor everything you are taking. Your doctor will especially watch for drugs that treat infections, depression, nausea and blood pressure, since these can increase your blood level of Fentora's active ingredient, fentanyl, raising your risk of side effects and of an overdose. Grapefruit and grapefruit juice do the same thing, so you should avoid them. Alcohol also increases the risk of serious side effects -- you shouldn't drink when taking this medication.

Some of the drugs you may need to avoid -- or which may prompt your doctor to adjust your Fentora dose -- include:
  • buprenorphine
  • butorphanol
  • carbamazepine
  • isocarboxazid
  • nalbuphine
  • naloxone
  • nalmefene
  • pentazocine
  • phenelzine
  • phenytoin
  • rifabutin
  • rifampin isocarboxazid
  • selegiline
  • St. John's wort
  • tranylcypromine
