Morphine Sulfate Solution for Injection is formulated for use by the intravenous route in Patient

specific department or unit protocols must be covered to ensure aseptic transfer of the contents of
the vial to the PCA system.
There is a considerable variation in analgesic requirements among patients and therefore
individualised treatment strategies are required. Dosage should be based on the severity of the
pain and the response and opiate tolerance of the patient.

Loading Dose
Loading doses of typically between 1mg and 10mg (maximum 15mg) of morphine sulfate may be
given by intravenous infusion over four or five minutes. The loading dose used will depend upon
the patient’s diagnosis and condition.
PCA demand dose
An initial demand dose of 1mg Morphine Sulfate Solution for Injection with a lockout period of 5 to
10 minutes is recommended. Dosages may vary depending on the loading dose, the tolerance and
condition of the patient, and whether a background infusion of morphine sulfate is being given.
The patient should be specifically monitored for pain, sedation and respiratory rate during the first
few hours of treatment to ensure that the dosage regimen is suitable.
The duration of treatment should be kept to a minimum, although dependence and tolerance are
not generally a problem when morphine is used legitimately in patients with opioid-sensitive pain.
Use in children:
Not recommended for children under 12 years.
Use in the elderly:
Morphine doses need to be reduced in elderly patients.
Morphine Sulfate Solution for Injection should not be mixed with other preparations.
