USES: This medication is used to help relieve sudden (breakthrough) cancer pain in people who are regularly taking moderate to large amounts of narcotic pain medication. Fentanyl belongs to a class of drugs known as narcotic (opiate) analgesics. It works in the brain to change how your body feels and responds to pain.This medication should not be used to relieve mild or short-term pain (such as due to headache/migraine, dental procedures, surgery).
HOW TO USE: Read the Medication Guide provided by your pharmacist before you start using fentanyl and each time you get a refill. Learn all usage and disposal instructions. If you have any questions, ask your doctor or pharmacist.Use this medication as directed by your doctor. Just before using, open the blister pack unit as directed. Do not push the tablet through the foil of the blister pack because this could damage the tablet. Place the tablet in your mouth either above a rear molar tooth between your upper cheek and gum or under the tongue. Leave the medication in place until it is dissolved (usually 14 to 25 minutes). Do not break, bite, chew, suck, or swallow the tablet whole. You may feel a gentle bubbling in your mouth while the tablet dissolves. Do not eat or drink anything while the tablet dissolves. If there is still some tablet left after 30 minutes, swallow it with a glass of water. If you are using the method that involves placing the tablet between your cheek and gum, remember to change sides of the mouth with each dose.Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your doctor or pharmacist says you may do so safely. Grapefruit can increase the chance of side effects with this medicine. Ask your doctor or pharmacist for more details.If you start to have side effects (such as dizziness, feeling sick to your stomach, severe drowsiness) before finishing a dose, your doctor may need to adjust your dose. Rinse your mouth with water and spit the rest of the tablet into a sink or toilet. Rinse the sink or flush the toilet afterward to finish proper disposal. Tell your doctor promptly if this happens.The dosage is based on your medical condition and response to treatment. If you need a second dose, wait 30 minutes after starting the first dose. Do not use more than 2 doses per episode of breakthrough pain. Wait at least 4 hours before using fentanyl buccal tablets again for another episode of breakthrough pain. Do not increase your dose, take the medication more frequently, or take it for a longer time than prescribed.Pain medications work best if they are used when the first signs of pain occur. If you wait until the pain has worsened, the medication may not work as well.You should continue to also take your long-acting narcotic medication as directed by your doctor. Other non-narcotic pain relievers (such as acetaminophen, ibuprofen) may also be prescribed with this medication. Ask your doctor or pharmacist if you have any questions about using fentanyl safely with other drugs.This medication may cause withdrawal reactions, especially if it has been used regularly for a long time or in high doses. In such cases, withdrawal symptoms (such as restlessness, watering eyes, runny nose, nausea, sweating, muscle aches) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Ask your doctor or pharmacist for more details, and report any withdrawal reactions immediately.When this medication is used for a long time, it may not work as well. Talk with your doctor if this medication stops working well.Along with its benefits, this medication may rarely cause abnormal drug-seeking behavior (addiction). This risk may be increased if you have abused alcohol or drugs in the past. Take this medication exactly as prescribed to lessen the risk of addiction.Tell your doctor if your pain persists or worsens, if you have more than 4 episodes of breakthrough pain daily, or if you need to use 2 doses of medication for each episode of pain.
