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
