Fentanyl lozenge can be harmful or fatal if taken by children, patients for whom it was not been prescribed, or patients who are not tolerant to narcotic (opioid) pain medicine. Keep fentanyl lozenge out of the reach of children.
Fentanyl lozenge is only for breakthrough pain caused by cancer in patients who are already using and are tolerant to around-the-clock narcotic pain medicine. Severe, sometimes life-threatening, breathing problems can occur in patients using fentanyl lozenge, especially in patients not already using other narcotic medicines or patients taking certain other medicines. Ask your health care provider if fentanyl lozenge may interact with other medicines that you take. Do not use fentanyl lozenge for pain that is short-term (including headache, dental pain, or migraine) or for pain that occurs after surgery or injuries.
Do NOT take more than the recommended dose or use more often than prescribed. You must wait at least 4 hours after your last dose of fentanyl lozenge before treating a NEW episode of breakthrough pain with fentanyl lozenge.
Do not switch brands of fentanyl lozenge without first talking with your doctor. Different brands may release different amounts of fentanyl lozenge into your body. This may cause severe and possibly fatal overdose. Talk with your doctor or pharmacist for more information.
Fentanyl lozenge is used for:
Managing breakthrough pain in cancer patients 16 years old and older who are already receiving and are tolerant to around-the-clock narcotic (opioid) medicines.

- Place the medicine between the cheek and lower gum, occasionally moving it from one side of the mouth to the other. Twirl the handle often.
- Suck on the lozenge for 15 minutes. Do not chew or bite the lozenge. If you bite or chew the lozenge, you will get less pain relief.

- If you begin to feel drowsy, dizzy, or sick to your stomach before you finish your dose, remove the medicine from your mouth and dispose of it right away by dissolving it in hot tap water.
- If you cannot finish an entire dose of fentanyl lozenge and cannot immediately dissolve the medicine in hot tap water, immediately put it in the temporary storage bottle for safe keeping. Push the unit into the opening on the top until it falls completely into the bottle. Properly dispose of the unit as soon as possible according to your doctor's instructions. Do not save open or partially used lozenges for future use.
- When you finish your dose and the medicine is completely gone, dispose of the handle in a place that is out of the reach of children. If any medicine is left on the handle when you are finished, put the handle under hot tap water until the medicine is gone. Dispose of the handle out of the reach of children and pets.
- If you notice that your medicine is a different color or shape, check with your pharmacist to make sure that you have the right medicine strength.
- If your breakthrough pain does NOT get better within 15 minutes after your first dose, you may take a second dose as directed by your doctor. If your breakthrough pain does not get better after the second dose, contact your doctor. Do NOT take more than 2 doses per episode of breakthrough pain.
- Wait at least 4 hours after your last dose of fentanyl lozenge before treating a NEW episode of breakthrough pain. If you have more than 4 episodes of breakthrough pain per day, tell your doctor.
