ACTIONS

Magnesium is the second most plentiful cation within cellular fluids. It is an important activator of many enzyme systems and deficits are accompanied by a variety of functional disturbances.

INDICATIONS

As an electrolyte replenisher in magnesium deficiencies.

CONTRAINDICATIONS

Magnesium Chloride Injection should not be administered if there is renal impairment, marked myocardial disease or to comatose patients.

WARNING

Do not use if a precipitate is present.

PRECAUTIONS

The usual precautions for parenteral administration should be observed. Administer with caution if flushing and sweating occurs. A preparation of a calcium salt should be readily available for intravenous injection to counteract potential serious signs of magnesium intoxication. As long as deep tendon reflexes are active it is probable that the patient will not develop respiratory paralysis. Respiration and blood pressure should be carefully observed during and after administration of Magnesium Chloride Injection.

Pregnancy

Animal reproduction studies have not been conducted with magnesium chloride. It is also not known whether magnesium chloride can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Magnesium Chloride should be given to a pregnant woman only if clearly needed.

ADVERSE REACTIONS

Flushing, sweating, sharply lowered blood pressure, hypothermia, stupor and ultimately respiratory depression.

DOSAGE AND ADMINISTRATION

For intravenous infusion: 4 grams in 250 mL of 5% Dextrose Injection, at a rate not exceeding 3 mL per minute. Serum magnesium levels should serve as a guide to continued dosage.

USUAL DOSAGE RANGE

1 to 40 grams daily.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.
