(5) A prior dose of morphine. A dose of morphine never should be
repeated within 2 hours. It should not be repeated at all, unless necessary to control
pain. It should not be repeated if there is any reason to believe that the first dose has

in shock, it should be given intravenously (by a medical officer) rather than

(liver) disease or infection.
g. Supply. Morphine injection is supplied in sterile cartridge- needle units
containing 8, 10, and 15 mg of the drug. This form of issue should be protected from
freezing, and in addition, the date on the package should be checked, since this drug is
subject to deterioration in 24 months or less. Available for field use is a collapsible tube
with needle attached (syrette), containing 16 mg of the drug (figure 3-1).
