PHARMACOLOGICAL ACTION: Magnesium is essential for the activity of many enzyme systems and plays an important role with regard to neuro-chemical transmission and muscular excitability.
INDICATIONS: MAGNESIT is a magnesium supplement for the treatment of hypomagnesaemia and magnesium deficiency.
CONTRA-INDICATIONS: Renal impairment and acute dehydration. Hypersensitivity to the ingredients.
DOSAGE AND DIRECTIONS FOR USE: The dosage schedule should be adjusted according to the severity of the magnesium deficiency. In hypomagnesaemia the drug should be given daily over a period of 4 weeks.
The average daily dose is 4,5 mg of magnesium (0,185 mmol) per kg body weight.
The following guidelines should be observed:
ADULTS AND CHILDREN OVER 10 YEARS:
2 tablets with fluid, three times daily before meals.
The contents of one sachet (5g) three times daily before meals.
The granules should be dissolved in half a glass of water, mineral water, tea or fruit juice.
SIDE-EFFECTS AND SPECIAL PRECAUTIONS: Diarrhoea and bowel discomfort may occur and in these cases the daily dose should be reduced.
KNOWN SYMPTOMS OF OVERDOSAGE AND PARTICULARS OF ITS TREATMENT: Fatigue due to prolonged treatment or the administration of high doses may be indicative of abnormally high serum magnesium concentrations. In such cases, treatment should be temporarily withdrawn and the serum magnesium levels should be determined.
Toxic effects due to overdose of MAGNESIT by the oral route have not been reported.
However, serum levels over 5 mmol/litre could cause respiratory difficulty and absence of the deep tendon reflexes. At 6 to 7,5 mmol/litre the patient could be comatose and concentrations exceeding 8 mmol/litre would lead to respiratory paralysis and diastolic cardiac arrest.
Subjects with renal insufficiency might develop hypermagnesaemia characterized by nausea, vomiting, lethargy and blockage of the bladder when the serum concentration of magnesium ranges from 2,5 to 4,5 mmol/litre.
