Can I use Fentora if I have a history of alcoholism?

If you have a history of alcoholism, you should talk with your doctor about whether you can use Fentora (fentanyl), a morphine-like drug for breakthrough cancer pain. Fentora can be habit-forming, especially for people who have had troubles with addiction in the past. You should not drink alcohol at all while using Fentora, since the combination can worsen side effects like sleepiness and increase the risk of a potentially fatal slowdown in your breathing. Still, you and your doctor may decide the pain relief offered by Fentora outweighs these dangers.
