Morphinedosage
1 ML morphine sulfate 4 MG/ML Injection
Dosage and administration
Morphine Sulfate Injection should be prescribed only by healthcare professionals who are knowledgeable about the use of opioids and how to mitigate the associated risks.
Use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals. Reserve titration to higher doses of Morphine Sulfate Injection for patients in whom lower doses are insufficiently effective and in whom the expected benefits of using a higher dose opioid clearly outweigh the substantial risks.
Many acute pain conditions (e.g., the pain that occurs with a number of surgical procedures or acute musculoskeletal injuries) require no more than a few days of an opioid analgesic. Clinical guidelines on opioid prescribing for some acute pain conditions are available.
Initiate the dosing regimen for each patient individually, taking into account the patient’s underlying cause and severity of pain, prior analgesic treatment and response, and risk factors for addiction, abuse, and misuse.
Respiratory depression can occur at any time during opioid therapy, especially when initiating the following dosage increases with Morphine Sulfate Injection. Consider this risk when selecting an initial dose and when making dose adjustments.
Direct Intravenous Injection: Initiate treatment with 0.1 mg to 0.2 mg per kg every 4 hours as needed to manage pain.
Intramuscular Injection: Initiate treatment with 10 mg, every 4 hours as needed to manage pain (based on a 70 kg adult).
Do not abruptly discontinue Morphine Sulfate Injection in a physically-dependent patient.
2.1 Important
Dosage and Administration Instructions
Morphine Sulfate Injection is intended for intravenous and intramuscular administration.
Morphine Sulfate Injection is available in three concentrations for direct injection. Dosing errors can result in accidental overdose and death. Avoid dosing errors that may result from confusion between mg and mL and confusion with morphine injections of different concentrations when prescribing, dispensing, and administering Morphine Sulfate Injection. Ensure that the dose is communicated and dispensed accurately.
Administration of Morphine Sulfate Injection should be limited to use by those familiar with the management of respiratory depression. Morphine must be injected slowly; rapid intravenous administration may result in chest wall rigidity.
Morphine Sulfate Injection should be prescribed only by healthcare professionals who are knowledgeable about the use of opioids and how to mitigate the associated risks.
Use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals. Because the risk of overdose increases as opioid doses increase, reserve titration to higher doses of Morphine Sulfate Injection for patients in whom lower doses are insufficiently effective and in whom the expected benefits of using a higher dose opioid clearly outweigh the substantial risks.
Many acute pain conditions (e.g., the pain that occurs with a number of surgical procedures or acute musculoskeletal injuries) require no more than a few days of an opioid analgesic. Clinical guidelines on opioid prescribing for some acute pain conditions are available.
There is a variability in the opioid analgesic dose and duration needed to adequately manage pain due both to the cause of pain and to individual patient factors. Initiate the dosing regimen for each patient individually, taking into account the patient’s underlying cause and severity of pain, prior analgesic treatment and response, and risk factors for addiction, abuse, and misuse.
Respiratory depression can occur at any time during opioid therapy, especially when initiating the following dosage increases with Morphine Sulfate Injection. Consider this risk when selecting an initial dose and when making dose adjustments.
Parenteral drug products should be inspected visually 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.
2.2 Initial
Dosage Direct Intravenous Injection Initiate treatment with Morphine Sulfate Injection in adults at a dosing range of 0.1 mg to 0.2 mg per kg every 4 hours as needed to manage pain, and at the lowest dose necessary to achieve adequate analgesia. Administer the injection slowly. Intramuscular Injection The initial IM dose is 10 mg every 4 hours (based on a 70 kg adult) as needed to manage pain, and at the lowest dose necessary to achieve adequate analgesia.
2.3 Titration and
Maintenance of Therapy Titrate the dose based upon individual patient’s response to their initial dose of Morphine Sulfate Injection. Individually titrate Morphine Sulfate Injection to a dose that provides adequate analgesia and minimizes adverse reactions. Continually reevaluate patients receiving Morphine Sulfate Injection to assess the maintenance of pain control, signs and symptoms of opioid withdrawal, and other adverse reactions, as well as monitoring for the development of addiction, abuse, or misuse. If the level of pain increases after dosage stabilization, attempt to identify the source of increased pain before increasing the Morphine Sulfate Injection dosage. If after increasing the dosage, unacceptable opioid-related adverse reactions are observed (including an increase in pain after a dosage increase), consider reducing the dosage. Adjust the dosage to obtain an appropriate balance between management of pain and opioid-related adverse reactions.
2.4 Safe Reduction or
Discontinuation of Morphine Sulfate Injection When a patient who has been taking Morphine Sulfate Injection regularly and may be physically dependent or no longer requires therapy with Morphine Sulfate Injection, taper the dose gradually, by 25% to 50% every 2 to 4 days, while regularly evaluating 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 Morphine Sulfate Injection in a physically-dependent patient.
