Fentanyl citrate treats "breakthrough" cancer pain that is not controlled by other medicines. This medication is not for treating pain that is not cancer-related, such as migraine headaches or pain after surgery.
Fentanyl citrate is available only from a certified pharmacy under a special program called Actiq REMS Program.
Fentanyl citrate may also be used for purposes not listed in this medication guide.

The Actiq transmucosal unit is a fentanyl citrate lozenge attached to a plastic handle. Each unit is wrapped in a child-proof blister pack. Cut the blister pack open with scissors when you are ready to use the unit.
Place the medicine in your mouth between your cheek and gum, and hold the handle with your fingers. Twirl the handle to move the medicine around in your mouth while sucking on it.
Allow the medicine to dissolve in your mouth for 15 minutes. Swallow when needed. Do not bite or chew the lozenge. Do not eat or drink anything while the unit is in your mouth. If you need to use a second unit, wait at least 15 minutes after you have finished the first unit. Use only 1 Actiq unit at a time.
If you feel dizzy or sick to your stomach before the medicine has completely dissolved, stop using the unit and call your doctor.
Do not stop using any other pain medicines your doctor has prescribed for you.
If you switch from using Actiq to using other forms of fentanyl, you will not use the same dose. Many forms of fentanyl are given at lower doses than Actiq. If you use the same dose of each medication, you may have life-threatening overdose symptoms.
Pay special attention to your dental hygiene. Fentanyl citrate can cause dry mouth leading to tooth decay.
Do not stop using fentanyl citrate suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using this medicine.
Store at room temperature away from moisture and heat. Leave each unit in its child-proof blister pack until you are ready to use it.
