What is fentanyl citrate (Actiq)?

Fentanyl citrate is an opioid pain medication. An opioid is sometimes called a narcotic.

Fentanyl citrate treats "breakthrough" cancer pain that is not controlled by other medicines. This medicine is not for treating pain that is not cancer-related, such as migraine headaches or pain after surgery.

Fentanyl citrate may also be used for purposes not listed in this medication guide.

What happens if I miss a dose?

Since fentanyl citrate is used for pain, you are not likely to miss a dose. Skip any missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.

What should I avoid while using fentanyl citrate?

Do not drink alcohol. Dangerous side effects or death could occur.

Fentanyl citrate may impair your thinking or reactions. Avoid driving or operating machinery until you know how this medicine will affect you. Dizziness or severe drowsiness can cause falls or other accidents.

Grapefruit and grapefruit juice may interact with fentanyl citrate and lead to unwanted side effects. Discuss the use of grapefruit products with your doctor.

Common side effects may include:

  • dizziness, mild drowsiness, depressed mood;
