Important Dosage and Administration Instructions
Do Not Use DURAMORPH in Continuous Microinfusion Devices.
DURAMORPH should be administered by or under the direction of a physician experienced in the techniques of epidural or intrathecal administration and familiar with the patient management problems associated with epidural or intrathecal drug administration and the labeling, and should take place only in settings where adequate patient monitoring is possible.
- Because of the risk of delayed respiratory depression, patients should be observed in a fully equipped and staffed environment for at least 24 hours. Respiratory depression (both early and late onset) has occurred more frequently following intrathecal administration than epidural administration.
- Because epidural administration has been associated with less potential for immediate or late adverse effects than intrathecal administration, the epidural route should be used whenever possible.
- For safety reasons, it is recommended that administration of DURAMORPH by the epidural or intrathecal routes be limited to the lumbar area.
- Have resuscitative equipment and a specific antagonist (naloxone injection) immediately available for the management of respiratory depression as well as complications which might result from inadvertent intrathecal or intravascular injection (note: intrathecal dosage is usually 1/10 that of epidural dosage).
Verify proper placement of a needle or catheter in the epidural space before DURAMORPH is injected.
Acceptable techniques for verifying proper placement include: a) aspiration to check for absence of blood or cerebrospinal fluid, or b) administration of 5 mL (3 mL in obstetric patients) of 1.5% PRESERVATIVE-FREE Lidocaine and Epinephrine (1:200,000) Injection and then observe the patient for lack of tachycardia (this indicates that vascular injection has not been made) and lack of sudden onset of segmental anesthesia (this indicates that intrathecal injection has not been made).
Safety and Handling Instructions:
DURAMORPH is supplied in sealed ampuls. Accidental dermal exposure should be treated by the removal of any contaminated clothing and rinsing the affected area with water.
Inspect parenteral drug products for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if color is darker than pale yellow, if it is discolored in any other way, or if it contains a precipitate.
DURAMORPH is intended for single use only. Protect from light, discard any unused portion. Do not heat-sterilize.
The starting dose of DURAMORPH must be individualized.
- Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and Precautions (5.3)].
- Initiate the dosing regimen for each patient individually, taking into account the patient's severity of pain, patient response, prior analgesic treatment experience, and risk factors for addiction, abuse, and misuse [see Warnings and Precautions (5.3)].
- Monitor patients closely for respiratory depression, especially within the first 24-72 hours of initiating therapy and following dosage increases with DURAMORPH and adjust the dosage accordingly [see Warnings and Precautions (5.2)].
Dosage for Intravenous Administration
Adult Dosage: The initial dose of morphine should be 2 mg to 10 mg/70 kg of body weight.
Dosage for Epidural Administration
Adult Dosage: Initial injection of 5 mg in the lumbar region may provide satisfactory pain relief for up to 24 hours. If adequate pain relief is not achieved within one hour, careful administration of incremental doses of 1 to 2 mg at intervals sufficient to assess effectiveness may be given. Do not administer more than 10 mg per 24 hours.
Dosage for Intrathecal Administration
Adult Dosage: Intrathecal dosage is usually 1/10 that of epidural dosage. A single injection of 0.2 to 1 mg may provide satisfactory pain relief for up to 24 hours. (Caution: this is only 0.4 to 2 mL of the 5 mg/10 mL ampul or 0.2 to 1 mL of the 10 mg/10 mL ampul of DURAMORPH).
- Do not inject intrathecally more than 2 mL of the 5 mg/10 mL ampul or 1 mL of the 10 mg/10 mLampul.
- Repeated intrathecal injections of DURAMORPH are not recommended. If pain recurs, consider consider alternative routes of administration
- A constant intravenous infusion of naloxone, 0.6 mg/hr, for 24 hours after intrathecal injection may be used to reduce the incidence of potential side effects.
Discontinuation of DURAMORPH
When a patient who has been treated with a regimen of opioid analgesics including DURAMORPH regularly and may be physically dependant no longer requires therapy with DURAMORPH, taper the dose gradually while monitoring carefully for signs and symptoms of withdrawal. If the patient develops these signs or symptoms, raise the dose to the previous level and taper more slowly, either by increasing the interval between decreases, decreasing the amount of change in dose, or both. Do not abruptly discontinue DURAMORPH in a physically-dependent patient [see Warnings and Precautions (5.12), Drug Abuse and Dependence (9.3)].
