- Dosage
- <p><strong>4.2 Dose and method of administration</strong></p>
<p>NOTE: Opioid antagonists and facilities for administration of oxygen and control of respiration should be available during, and immediately following parenteral administration.</p>
<p><strong>Subcutaneous, intramuscular and slow intravenous administration</strong><br>
See also Method of administration.</p>
<p><strong>Adults</strong>: Morphine sulfate is usually administered by intramuscular or subcutaneous injection, in the range of 5 to 20 mg, depending on the cause of pain and the patient response. Doses may be repeated every 4 to 6 hours.<br>
Morphine sulfate may also be given intravenously when a rapid onset of action is desired. The dose is usually in the range of 2.5 to 15 mg given as diluted solution slowly over 4 to 5 minutes.</p>
<p><strong>Children</strong>: Morphine sulfate is given by intramuscular or subcutaneous injection in doses of 0.1 to 0.2 mg/kg bodyweight to a maximum of 15 mg. Injection may be repeated every 4 to 6 hours.</p>
<p>When a rapid onset of action is desirable, in a closely monitored environment, morphine may be titrated intravenously with caution, in a dose of 0.05 to 0.1 mg/kg, incrementally over 5 to 15 minutes. Repeat intravenous dosing is unsubstantiated as a method of analgesia in children.</p>
<p>Morphine sulfate is not usually given pre-operatively in children under 1 year, and it should be given with extreme care to neonates. It should not be given to premature infants (see section 4.3).</p>
<p><strong>Continuous intravenous infusion</strong><br>
The dosage of morphine should be titrated according to the patient’s analgesic requirements and previous opiate experience. For the management of acute pain via intravenous infusion, most adults with no previous history of opioid intake can be continued on 0.5 to 2.0 mg/hr after adequate analgesia has been established.</p>
<p>In children, an infusion dose of 0.01 to 0.05 mg/kg/hr morphine to a maximum intravenous dose of 4 mg/hr is recommended.</p>
<p>It is recommended that an opioid antagonist and equipment for artificial ventilation be available.</p>
<p><strong>Patient-controlled analgesia (PCA)</strong><br>
Patient-controlled analgesia allows patients to assess their own level of pain and consequently titrate the amount of morphine they require for adequate pain control against sedation and other side effects.</p>
<p>The dosages and time intervals are preset into a microprocessor-controlled infusion pump. When the patient experiences pain, a button is depressed by the patient and a dose of morphine is administered intravenously. If the patient should depress the button before the preset time interval (lockout interval) has elapsed, no extra drug is administered. For adults, demand doses of 0.5 to a maximum of 1.5 mg morphine have been given via PCA using a lockout interval of 6 to 10 minutes. Along with the self-administered dose of morphine, some syringe pumps also deliver a background continuous infusion of morphine at a basal rate. If a background infusion is adopted, a dose of 1 mg/hr morphine is often used in adults. Some PCA pumps allow a maximum dosage over a defined period to be preset in order to avoid patient overdosage.</p>
<p>There is limited clinical experience of the use of PCA in children. However, a demand dose of 0.01 to 0.025 mg/kg morphine has been used successfully in children and adolescents between the ages of 7 and 19 years with a lockout interval of 6 to 10 minutes. If a background infusion is employed, an infusion dose of 0.015 mg/kg/hr morphine may be used in children.</p>
<p>The demand dosage and lockout interval should be determined according to the patient’s analgesic requirements. Patients receiving a background infusion of morphine should generally receive a smaller demand dose relative to equivalent patients utilising a demand dose only.</p>
<p>Techniques such as PCA with background continuous infusion are associated with a higher rate of adverse effects and require close monitoring.</p>
<p><strong>General information for cancer pain</strong><br>
When morphine is administered by continuous intravenous or subcutaneous infusion for relief of severe, chronic pain associated with cancer, the dosage of morphine must be individualised according to the response and tolerance of the patient. In some patients with exceptionally severe, chronic pain it may be necessary to exceed the usual dosage. Reduced dosage is indicated in poor-risk patients, in very young or very old patients, and in patients receiving other CNS depressants.</p>
<p>Orally administered morphine should be used in preference to parenteral morphine whenever adequate pain control can be achieved by this route. However, oral morphine is often inadequate or impractical in the terminally ill patient.</p>
<p>Patients being converted from oral morphine to either intramuscular, intravenous or subcutaneous morphine require dosage reduction (about one-sixth), since about 60% of oral morphine is metabolised in first-pass metabolism (i.e. 1 mg of either intramuscular, subcutaneous or intravenous morphine for every 6 mg of oral morphine). The dose should then be titrated according to the patient’s clinical response.</p>
<p>For cancer pain, morphine sulfate should be given regularly around the clock, in most instances every 4 hours. The basis of pain control with morphine sulfate should be regular scheduling rather than on an ‘as required’ or PRN narcotic order. Patients requiring high doses of morphine usually need to be awakened for medication during the night to prevent morning pain.</p>
<p><strong>Morphine dosage increases</strong><br>
Dosage increases for intravenous, subcutaneous or intramuscular administration of morphine should not be made more frequently than every 24 hours, since it will take approximately 4 to 5 morphine half-lives to attain a new steady state concentration in a patient with normal liver and kidney function.</p>
<p>Following all dosage increases, the patient must be monitored closely for side effects, the most common being sedation, nausea, vomiting, constipation and hypotension.</p>
<p><strong>Method of administration</strong><br>
For intravenous, intramuscular or subcutaneous use.<br>
The subcutaneous route is not suitable for oedematous patients.</p>
