Relief of breakthrough pain in adult cancer patients tolerant to opioid medications
This medication is used in adults 18 years of age and older who are currently receiving opioid therapy for persistent pain. It is particularly effective in relieving breakthrough pain experienced by cancer patients. That is, it helps manage severe pain that suddenly occurs despite the use of existing analgesics. By managing breakthrough pain, it contributes to reducing patients' pain and improving their quality of life.
This medicine should be administered by the nasal route only. It is recommended that this medicine be administered while sitting or standing upright. When using this medicine for the first time, spray it into the air 3 ~ 4 times before use to ensure that a uniform spray is produced. If it has not been used for 7 days or longer, spray it into the air once before use to clear any residue. Clean the tip of the nasal spray after each dose. Each spray of this medicine contains 200 µg of fentanyl. This medicine may be used for up to 4 episodes of breakthrough pain per day. For a single episode of breakthrough pain, no more than 2 doses of this medicine should be administered, with an interval of at least 10 minutes between doses. A dose for another episode of breakthrough pain should be administered at least 4 hours later. The initial dose is 50 µg administered as 1 spray into one nostril. For an episode of breakthrough pain, titrate the dose (50, 100, 200 µg) until a single dose of this medicine provides adequate pain relief while minimizing adverse reactions. If adequate pain relief is not achieved, a second dose may be administered after 10 minutes. No more than 2 doses of this medicine should be administered for a single episode of breakthrough pain. A dose for another episode of breakthrough pain should be administered at least 4 hours later. If adequate pain relief is not achieved, the same dose may be readministered after at least 10 minutes. No more than 2 doses of this medicine should be administered for a single episode of breakthrough pain. A dose for another episode of breakthrough pain should be administered at least 4 hours later. In general, if more than one dose is required during several consecutive episodes of breakthrough pain, increase the maintenance dose of this medicine. If breakthrough pain occurs more than 4 times per day, the dose of the opioid used as the baseline treatment for persistent pain should be adjusted. If this medicine is not tolerated or adverse reactions persist, reduce the dose or replace treatment with another analgesic. If breakthrough pain no longer occurs, discontinue this medicine immediately. Treatment for persistent background pain should be maintained. If it is necessary to discontinue all opioid medicines, the dose should be tapered gradually under the physician's instructions to avoid effects from sudden discontinuation.
