Proper Use

Drug information provided by: Micromedex

Fentanyl nasal sprays are for use in opioid-tolerant patients only. If you are not sure whether or not you are opioid-tolerant, check with your doctor before using this medicine.

It is very important that you understand the requirements of the Lazanda® REMS program, and become familiar with the Lazanda® Medication Guide. Ask your doctor or pharmacist before starting treatment with this medicine.

This medicine is for use only in the nose. Do not get any of it in your eyes or on your skin. If it does get on these areas, rinse it off with water right away.

Fentanyl nasal spray works differently than other fentanyl products, even at the same dose (number of milligrams). Do not substitute or convert it to other products containing fentanyl.

To use the nasal spray:

  • Keep the spray in the child-resistant container until ready to use.
  • If you are using the nasal spray for the first time, you will need to prime the spray. To do this, you should release four sprays into the pouch. Now it is ready to use.
  • Before using this medicine, gently blow your nose to clear the nostrils.
  • Insert the tip of the Lazanda® bottle into the nose. Point towards the bridge of the nose and tilt the bottle slightly.
  • Press down firmly on the finger grips until you hear a "click" sound and the number in the dose counter window adds up. This confirms a spray has been taken.
  • Return the spray bottle to the child-resistant container after each use.


The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

  • For nasal dosage form (spray):
    • For cancer pain:
      • Adults—At first, 100 micrograms (mcg) or 1 spray in one nostril during an episode of breakthrough cancer pain. Your doctor may increase your dose as needed and tolerated, up to a maximum of 800 mcg or 1 spray containing 400 mcg of fentanyl in each nostril. However, patients should not use more than 4 doses per 24 hours. Wait at least 2 hours before treating another episode of breakthrough cancer pain. If pain relief is not achieved within 30 minutes, a rescue medicine may be used as directed by your doctor. Patients should record their use over several episodes of breakthrough cancer pain and review their experience with their doctor to determine if a dosage adjustment is warranted.
      • Children—Use and dose must be determined by your doctor.


Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

Keep out of the reach of children.

Do not keep outdated medicine or medicine no longer needed.

Ask your healthcare professional how you should dispose of any medicine you do not use.

Throw away any unused spray bottle and start using a new one after 5 days or more since it has been used or 14 days or more since it has been primed. Dispose any used, partially used, or unneeded spray bottles by emptying and spraying the remaining solution into the pouch. The sealed pouch and the empty bottle should be placed in a child-resistant container before discarding it in the trash can. Wash your hands with soap and water right away after handling the pouch.
