Uses

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 Actiq Lozenge On A Handle
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.
A Child Safety Kit is available from the manufacturer. It contains important safety and educational materials and a safe storage container to keep this medication out of reach of children. If you have any questions about the materials in this kit, bring them to your doctor or pharmacist, or contact the manufacturer.
Use fentanyl lozenges as directed by your doctor. Just before using, open the package with scissors. Remove the lozenge and place the medication end in your mouth between your cheeks and gums. Actively suck on the medication. Twirl the handle often and move the medication along the cheeks in your mouth, occasionally switching sides of the mouth. You should finish the medication in 15 minutes to get the most relief. Do not bite or chew the medication. You may drink some water before using this medication, but do not eat or drink anything while you are using it.
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. Remove the rest of the lozenge from your mouth and store or dispose of it properly (see Medication Guide). 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 lozenges again for another episode of breakthrough pain. To avoid any confusion and chance of overdose, you should only keep a supply of one strength of this medication. Do not increase your dose, take the medication more often, 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 opioid medication as directed by your doctor. Other pain relievers (such as acetaminophen, ibuprofen) may also be prescribed. Ask your doctor or pharmacist about using fentanyl safely with other drugs.
Suddenly stopping this medication may cause withdrawal, especially if you have used it for a long time or in high doses. To prevent withdrawal, your doctor may lower your dose slowly. Tell your doctor or pharmacist right away if you have any withdrawal symptoms such as restlessness, mental/mood changes (including anxiety, trouble sleeping, thoughts of suicide), watering eyes, runny nose, nausea, diarrhea, sweating, muscle aches, or sudden changes in behavior.
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.

Warnings

Do not use fentanyl lozenges unless you have been regularly taking moderate to large amounts of opioid pain medication. Otherwise, it may cause overdose (even death). To lower your risk, your doctor should have you use the smallest dose of fentanyl that works, and use it for the shortest possible time. See also How to Use section for more information about addiction.
Ask your doctor or pharmacist if you should have naloxone available to treat opioid overdose. Teach your family or household members about the signs of an opioid overdose and how to treat it.
The risk for severe breathing problems is higher when you start this medication and after a dose increase, or if you use the wrong dose/strength. Using this medication with alcohol or other drugs that can cause drowsiness or breathing problems may cause very serious side effects, including death. Be sure you know how to use fentanyl and what other drugs you should avoid using with it. See also Drug Interactions section. Get medical help right away if any of these very serious side effects occur: slow/shallow breathing, unusual lightheadedness, severe drowsiness/dizziness, difficulty waking up.
Carefully follow the specific directions for using fentanyl lozenges. Since they are not taken the same way, different forms of fentanyl (including lozenges, buccal tablets, patches) do not have the same effects at equal strengths and should not be substituted for each other. Tell your doctor or pharmacist of all medications that you use, especially of drugs that can affect how fentanyl works. Do not start, stop, or change the dosage of any medicines you are using without your doctor’s approval.

Also, using it for a long time or in high doses near the expected delivery date may harm the unborn baby. To lessen the risk, use the smallest effective dose for the shortest possible time. Babies born to mothers who use this drug for a long time may develop severe (possibly fatal) withdrawal symptoms.

Other medications can affect the removal of fentanyl from your body, which may affect how fentanyl works. Examples include azole antifungals (such as itraconazole, ketoconazole), calcium channel blockers (such as diltiazem, verapamil), HIV protease inhibitors (such as nelfinavir), macrolide antibiotics (such as erythromycin), mifepristone, nefazodone, rifamycins (such as rifabutin), ritonavir, certain drugs used to treat seizures (such as carbamazepine, phenytoin), among others.
Taking MAO inhibitors with this medication may cause a serious (possibly fatal) drug interaction. Avoid taking MAO inhibitors (isocarboxazid, linezolid, metaxalone, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, safinamide, selegiline, tranylcypromine) during treatment with this medication. Most MAO inhibitors should also not be taken for two weeks before treatment with this medication. Ask your doctor when to start or stop taking this medication.
The risk of serious side effects (such as slow/shallow breathing, severe drowsiness/dizziness) may be increased if this medication is used with other products that may also cause drowsiness or breathing problems. Tell your doctor or pharmacist if you are taking other products such as other opioid pain or cough relievers (such as codeine, hydrocodone), alcohol, marijuana (cannabis), drugs for sleep or anxiety (such as alprazolam, lorazepam, zolpidem), muscle relaxants (such as carisoprodol, cyclobenzaprine), or antihistamines (such as cetirizine, diphenhydramine).
Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain ingredients that cause drowsiness. Ask your pharmacist about using those products safely.
The risk of serotonin syndrome/toxicity increases if you are also taking other drugs that increase serotonin. Some examples are street drugs such as MDMA/ “ecstasy,” St. John’s wort, certain antidepressants (such as SSRIs like fluoxetine/paroxetine, SNRIs like duloxetine/venlafaxine), among others. The risk of serotonin syndrome/toxicity may be more likely when you start or increase the dose of these drugs.
