Common Medications That Affect Magnesium
Milk of Magnesia taken as a laxative or antacid can increase magnesium intake:
Taking the recommended dose as a laxative (2 to 4 Tbsp.) provides 990 to 1950 mg magnesium.
Taking the recommended dose as an antacid (1 to 3 tsp.) provides 165 to 500 mg magnesium.
Medications that can cause high serum magnesium:
Lithium Carbonate
Listed below are medications that increase the urinary excretion of magnesium:
Drugs used in heart disease
Antiarrhythmic Drugs
Quinidine, Sotalol, Aamiodarone, Bretylium
Digoxin and Strophanthin
Adrenalin and drugs that mimic its activity, such as isoproterenol
Diuretics
Furosemide
Ethacrynic Acid
Thiazides
Osmotic Agents
Drugs to treat allergies
Anti-asthmatics
Adrenalin
Aminophylline
Antihistamines: astemizole, terfenadine
Drugs used in mental disorders
pimozide
thioridazine, trifluoperazine
Antibiotics

Amphotericin B
Aminoglycoside group of antibiotics
Gentamicin
Tobramycin
Other medications
Antineoplastic drugs and radiation
