Special Warnings and Special Precautions for Use
As with other morphine preparations, Kaolin and Morphine Mixture should be
used with caution in the elderly, in hypothyroidism, in renal and hepatic
disease, adrenocortical insufficiency, prostatic hypertrophy, shock or reduced
respiratory reserve and should not be given if paralytic ileus is likely to occur.
In view of the sodium bicarbonate content, Kaolin and Morphine Mixture
should be administered with caution in patients with congestive heart failure,
hypertension and receiving corticosteroids. It is also not recommended in
metabolic or respiratory alkalosis, hypocalcaemia or hypochlorhydria.
Do not exceed the stated dose. If symptoms persist, consult your doctor.
Shake the bottle.
Interactions with other Medicinal Products and other Forms of
The adsorbent effects of kaolin, the reduction in intestinal motility produced
by morphine, and the antacid effect of sodium bicarbonate may reduce or
delay the absorption of other drugs from the gastrointestinal tract when given
The depressant effects of morphine may potentiate the effects of tranquillisers,
anaesthetics, hypnotics, sedatives and alcohol.
Pregnancy and Lactation
Kaolin and Morphine Mixture should not be used during pregnancy or
lactation unless the physician considers it necessary.
Morphine is known to cross the placenta, and is excreted in the breast milk
although therapeutic doses are unlikely to affect the infant.
Effects on Ability to Drive and Use Machines
Morphine may cause drowsiness and patients should not drive or operate
machinery if so affected.
Prolonged use of morphine may produce tolerance and psychological and
physical dependence. Morphine may cause nausea and vomiting, constipation,
drowsiness and confusion. Large doses may produce respiratory depression
Sodium bicarbonate may cause flatulence and prolonged use may lead to
Signs of morphine toxicity and overdosage include pin-point pupils,
respiratory depression and hypotension, circulatory failure and deepening
coma may occur in more severe cases.
Excessive administartion of sodium bicarbonate may lead to metabolic
Emergency procedures and antidotes
Administration of naloxone. Aspiration and gastric lavage with supportive
therapy such as replacement of fluids and electrolytes and assisted respiration
The possibility of intestinal obstruction should be investigated because of the
Kaolin adsorbs toxic and other substances from the gastrointestinal tract and
increases stool bulk.
Morphine reduces intestinal motility.
Sodium bicarbonate is an alkalising agent and antacid.
Kaolin is not absorbed and remains unchanged throughout transit of the
Morphine is rapidly, but variably, absorbed from the gastrointestinal tract with
peak levels occurring in 30 - 120 minutes. Bioavailability by the oral route is
only about 30% due to significant first-pass metabolism in the liver. The
mean plasma half-life is 3 hours (range 1 - 5 hours). It is distributed
throughout the body but mainly in the kidneys, liver, lungs and spleen with
lower concentrations in the brain and muscles. Morphine diffuses across the
placenta and traces also appear in milk (less than 1%) and sweat. About 35%
is protein bound.
Conjugation to morphine 3- and 6-glucuronides occurs in the liver. About
10% of a dose of morphine is excreted through the bile into the faeces and the
remainder is excreted in the urine. About 90% of total morphine is excreted in
24 hours with traces up to 48 hours.
Sodium bicarbonate, not used in neutralising gastric acid with the production
of carbon dioxide, is absorbed and in the absence of a deficit of bicarbonate in
the plasma, bicarbonate ions are excreted in the urine together with sodium
