Therapeutic Indications

Uses

Magnesium deficiency

Administration

Can be dissolved in 50ml to 200 ml water, tea or orange juice. Stir until the solution in water is cloudy to transparent. In orange juice or tea inactive particles will be visible. The solution should be taken immediately following reconstitution or within 24 hours when dissolved in bottled water and stored below 25 degrees celsius.

If necessary, magnesium aspartate dissolved in 200ml water can be administered via a gastric, duodenal, and nasal feeding tube. This should be administered immediately following reconstitution or within 24 hours when dissolved in bottled water and stored below 25 degrees celsius.

Contraindications

Children under 2 years
Bradycardia
Hereditary fructose intolerance
Renal impairment - creatinine clearance below 30 ml/minute

Precautions and Warnings

Glucose-galactose malabsorption syndrome

Preparation contains sucrose
Monitor serum electrolytes
Interrupt or reduce dose if diarrhoea occurs
Prolonged treatment may lead to dental caries

Pregnancy and Lactation

Pregnancy

Magnesium aspartate can be used during pregnancy if clinically needed.

Data from more than 1000 pregnancy outcomes indicate no malformative nor feto/neonatal toxicity of magnesium.

The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14 to 17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame. Further advice may be available from the UK National Teratology Information Service (NTIS) and through ToxBase, available via password on the internet ( www.toxbase.org ) or if this is unavailable at the backup site ( www.toxbasebackup.org ).

Lactation

Magnesium aspartate can be used during breastfeeding.

Magnesium aspartate and it's metabolites are excreted in human milk, but at therapeutic doses, no effects on the breastfed newborn or infant are anticipated.

Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.
