Actiq is used for the management of cancer pain in patients with malignancies who are already receiving and who are tolerant to opioid therapy for their underlying persistent cancer pain.

Actiq is used to relieve the flares, called breakthrough cancer pain, that your regular prescribed pain medication does not control.

Actiq should not be used for:

• Short-term pain, e.g. pain from injuries or surgery
• Pain that is already being treated with a prescription opioid (narcotic) pain medicine every day on a regular schedule

Sleepiness, nausea or dizziness.

Actiq contains a prescription opioid (narcotic) pain-relieving medicine called fentanyl. When you place it in your mouth it slowly dissolves, and the medicine is absorbed through the lining of your mouth. From there, it goes into your bloodstream.
