Fentanyl sublingual spray should be prescribed by doctors who are experienced in treating pain in cancer patients. It should be used only to treat breakthrough cancer pain (sudden episodes of pain that occur despite around-the-clock treatment with pain medication) in cancer patients at least 18 years of age 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. This medication should not be used to treat pain other than chronic cancer pain, especially short-term pain such as migraines or other headaches, pain from an injury, or pain after a medical or dental procedure. Fentanyl sublingual spray may cause serious breathing problems or death if it is used by people who are not being treated with other narcotic medications or who are not tolerant to narcotic medications.
Fentanyl sublingual spray may cause serious harm or death if used accidentally by a child or by an adult who has not been prescribed the medication. Even used fentanyl sublingual spray containers may contain enough medication to cause serious harm or death to children or other adults. Keep fentanyl sublingual spray out of reach of children. Ask your doctor how to obtain a kit from the manufacturer containing child safety locks and other supplies to prevent children from getting the medication. Dispose of unused doses of fentanyl according to the manufacturer's directions. If fentanyl sublingual spray is used by a child or an adult who has not been prescribed the medication, get emergency medical help.
Fentanyl sublingual spray should be used along with your other pain medication(s). Do not stop taking your other pain medication(s) when you begin your treatment with fentanyl sublingual spray. If you stop taking your other pain medication(s) you will need to stop using fentanyl sublingual spray.
Taking certain medications with fentanyl sublingual spray may increase the risk that you will develop serious or life-threatening breathing problems. Tell your doctor if you are taking any of the following medications: certain antibiotics such as clarithromycin (Biaxin, in PrevPac), erythromycin (Erythocin), telithromycin (Ketek), and troleandomycin (TAO) (not available in the United States); certain antifungals such as fluconazole (Diflucan), itraconazole (Sporanox), and ketoconazole (Nizoral); aprepitant (Emend); diltiazem (Cardizem, Dilacor, Tiazac, others); certain medications for human immunodeficiency virus (HIV) such as amprenavir (Agenerase), fosamprenavir (Lexiva), indinavir (Crixivan), nelfinavir (Viracept), ritonavir (Norvir, in Kaletra), and saquinavir (Invirase); nefazodone (Serzone); or verapamil (Calan, Covera, Verelan). Your doctor may need to change the dosages of your medications and will monitor you carefully.
Fentanyl comes as several other types of products. The medication in each product is absorbed differently by the body, so one product cannot be substituted for any other fentanyl product. If you are switching from one product to another, your doctor will prescribe a dose that is best for you.
A program has been set up to decrease the risk of using this medication. Your doctor will need to enroll in the program in order to prescribe fentanyl and you will need to have your prescription filled at a pharmacy that is enrolled in the program. As part of the program, your doctor will talk with you about the risks and benefits of using fentanyl and about how to safely use, store, and dispose of the medication. After you talk with your doctor, you will sign a form acknowledging that you understand the risks of using fentanyl and that you will follow your doctor's instructions to use the medication safely. Your doctor will give you more information about the program and how to get your medication and will answer any questions you have about the program and your treatment with fentanyl.

Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website ( Web Site) or the manufacturer's website to obtain the Medication Guide.

Fentanyl sublingual spray is used to treat breakthrough pain (sudden episodes of pain that occur despite round the clock treatment with pain medication) in cancer patients 18 years of age and older 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.
Fentanyl comes as a solution (liquid) to spray sublingually ( under the tongue). It is used as needed to treat breakthrough pain, but not more often than directed by your doctor. 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 sublingual spray and gradually increase your dose until you find the dose that will relieve your breakthrough pain. Use one dose of fentanyl sublingual spray for breakthrough pain. If you are still in pain after your first dose, use a second dose 30 minutes after your first dose. Do not use more than two doses per breakthrough pain episode. After you treat an episode of pain using one or two doses of fentanyl sublingual spray, wait at least 4 hours after using fentanyl sublingual spray before treating a new episode of breakthrough pain. If you have more than four episodes of breakthrough cancer pain in a day, call your doctor.
