Why is this medication prescribed?

Fentanyl is used to treat breakthrough pain (sudden episodes of pain that occur despite round the clock treatment with pain medication) in cancer patients at least 18 years of age (or at least 16 years of age if taking Actiq brand lozenges) who are taking regularly scheduled doses of another narcotic (opiate) pain medication, and who are tolerant (used to the effects of the medication) to narcotic pain medications. Fentanyl is in a class of medications called narcotic (opiate) analgesics. It works by changing the way the brain and nervous system respond to pain.


How should this medicine be used?

Fentanyl comes as a lozenge on a handle (Actiq), a sublingual (underneath the tongue) tablet (Abstral), a film (Onsolis), and a buccal (between the gum and cheek) tablet (Fentora) to dissolve in the mouth. Fentanyl is used as needed to treat breakthrough pain, but not more often than four times a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.

Your doctor will probably start you on a low dose of fentanyl and gradually increase your dose until you find the dose that will relieve your breakthrough pain. If you still have pain 30 minutes after using fentanyl films (Onsolis), your doctor may tell you to use another pain medication to relieve that pain, and may increase your dose of fentanyl films (Onsolis) to treat your next episode of pain . Talk to your doctor about how well the medication is working and whether you are experiencing any side effects so that your doctor can decide whether your dose should be adjusted.

Do not use fentanyl more than four times a day. Call your doctor if you experience more than four episodes of breakthrough pain per day. Your doctor may need to adjust the dose of your other pain medication(s) to better control your pain.

Fentanyl may be habit forming. Use fentanyl exactly as directed. Do not use a larger dose of fentanyl, use the medication more often, or use it for a longer period of time than prescribed by your doctor.

Do not stop using fentanyl without talking to your doctor. Your doctor may decrease your dose gradually. If you suddenly stop using fentanyl, you may experience unpleasant withdrawal symptoms.

To use fentanyl lozenges (Actiq), follow these steps:
Check the blister package and the handle of the lozenge to make sure the lozenge contains the dose of medication you have been prescribed.Use scissors to cut open the blister package and remove the lozenge. Do not open the blister package until you are ready to use the medication.Place the lozenge in your mouth, between your cheek and gum. Actively suck on the lozenge, but do not chew or bite it. Move the lozenge around in your mouth, from one side to the other, using the handle. Twirl the handle often.Do not eat or drink anything while the lozenge is in your mouth.Finish the lozenge in about 15 minutes.If you begin to feel dizzy, very sleepy, or nauseated before you have finished the lozenge, remove it from your mouth. Dispose of it immediately as described below or put it in the temporary storage bottle for later disposal.If you finish the entire lozenge, throw the handle away in a garbage can that is out of the reach of children. If you did not finish the entire lozenge, hold the handle under hot running water to dissolve all the medication, and then throw the handle away in a garbage can that is out of the reach of children and pets.To use fentanyl buccal tablets (Fentora), follow these steps:
Separate one blister unit from the blister card by tearing along the perforations. Peel back the foil to open the blister unit. Do not try to push the tablet through the foil. Do not open the blister unit until you are ready to use the tablet.Place the tablet in your mouth above one of your upper back teeth between your cheek and your gum.Leave the tablet in place until it dissolves completely. You may notice a gentle bubbling feeling between your cheek and gum as the tablet dissolves. It may take 14 to 25 minutes for the tablet to dissolve. Do not split, chew, bite, or suck the tablet.If any of the tablet is left in your mouth after 30 minutes, swallow it with a drink of water.If you begin to feel dizzy, very sleepy, or nauseated before the tablet dissolves, rinse your mouth with water and spit the remaining pieces of tablet into the sink or toilet. Flush the toilet or rinse the sink to wash away the tablet pieces.To use fentanyl sublingual tablets (Abstral), follow these steps:
Take a sip of water to moisten your mouth if it is dry. Spit out or swallow the water. Make sure your hands are dry before handling the tablet.Separate one blister unit from the blister card by tearing along the perforations. Peel back the foil to open the blister unit. Do not try to push the tablet through the foil. Do not open the blister unit until you are ready to use the tablet.Place the tablet under your tongue as far back as you can. If more than 1 tablet is needed for your dose, spread them around on the floor of your mouth under your tongue.Leave the tablet in place until it dissolves completely. Do not suck, chew, or swallow the tablet.Do not eat or drink anything until the tablet is completely dissolved and you no longer feel it in your mouth.To use fentanyl films (Onsolis), follow these steps:
Use scissors to cut along the arrows of the foil package to open it. Separate the layers of the foil package and remove the film. Do not open the foil package until you are ready to use the medication. Do not cut or tear the film.Use your tongue to wet the inside of your cheek, or if needed, rinse your mouth with water to wet the area where you will place the film.Hold the film on a clean, dry finger, with the pink side facing up. Place the film in your mouth, with the pink side against the inside of your moistened cheek. With your finger, press the film against your cheek for 5 seconds. Then remove your finger and the film will stick to the inside of your cheek. If more than one film is needed for your dose, do not put the films on top of each other. You may place the films on either side of your mouth.Leave the film in place until it dissolves completely. The film will release a minty flavor as it dissolves. It may take 15 to 30 minutes for the film to dissolve. Do not chew or swallow the film. Do not touch or move the film while it dissolves.You may drink liquids after 5 minutes, but do not eat anything until the film dissolves completely.
