Magnesium hydroxide

Chemical formula: Hâ‚‚MgOâ‚‚  Molecular mass: 58.32 g/mol  PubChem compound: 73981

Interactions

Magnesium hydroxide interacts in the following cases:

Salicylates

The excretion of salicylates will be increased by changes in urinary pH.

Ibuprofen, warfarin

Magnesium hydroxide may increase the absorption of ibuprofen and warfarin.

Penicallamine, bisphosphates, ketoconazole, tetracycline

Magnesium hydroxide may decrease the absorption of penicallamine, bisphosphates, ketoconazole and tetracycline.

Sodium polystyrene sulphonate

Co-administration of magnesium hydroxide with sodium polystyrene sulphonate results in a relative excess of bicarbonate ions, which are absorbed, and may lead to metabolic alkylosis.

Pregnancy

Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/foetal development, parturition or postnatal development.

Nursing mothers

Magnesium crosses the placenta and is excreted in small amounts in breast milk. Use during pregnancy and lactation should be avoided unless on the advice of a doctor.

Effects on ability to drive and use machines

Magnesium hydroxide is unlikely to cause any effects on the ability to drive and use machines.

Adverse reactions


Diarrhoea may occur which is dose related.

In patients with impaired renal function there may be sufficient accumulation of magnesium to produce toxic effects.

Cross-check medications

Review your medication to ensure that there are no potentially harmful drug interactions or contraindications.
