peripheral vasodilation, drowsiness, confusion, loss of tendon reflexes due to
neuromuscular blockade, muscle weakness, respiratory depression, cardiac
arrhythmias, coma and cardiac arrest.

as with all medicines, use during early pregnancy should be avoided. Use
during later pregnancy and lactation is not considered to be a hazard.
Effects on ability to drive and use machines
Overdose (or excessive or prolonged intake) may give rise to
hypermagnesaemia, with symptoms as described in other special warnings and
precautions above. Treatment: Calcium Gluconate injection 10% should be
administered intravenously in a dose of 10 to 20ml to counteract respiratory
depression or heart block. If renal function is normal, adequate fluids should

necessary if patients with renal impairment or severe hypermagnesaemia.
Magnesium trisilicate is an antacid with slow acid neutralising action and mild
Magnesium Trisilicate is broken down to magnesium chloride and hydrated
silica gel by neutralisation in the stomach. About 5% of the magnesium is
absorbed and traces of the liberated silica may be absorbed and excreted in the
