Do not use if you are pregnant or allergic to sulfer.
Epsom-salt baths are contraindicated in cardiovascular or high-blood-pressure conditions. Ask your doctor, in such a case, whether you may take the bath.
Hypermagnesemia is a potentially lethal condition that may not be as rare as is commonly thought. In 1990, Whang and Ryder[12] studied more than 1,000 patients admitted to a community hospital and found the incidence of hypermagnesemia to be 5.7%, whereas only 12% of those were clinically suspected. Hypermagnesemia is usually found in patients with renal insufficiency who have a creatinine clearance of less than 30 mL/min. Other patients at risk for development of elevated serum magnesium levels are patients with excessive magnesium loads.
Potential sources of excess magnesium intake include antacids, laxatives, cathartics, and parenteral administration. Other less common causes of hypermagnesemia include rhabdomyolysis, tumor lysis syndrome, adrenal insufficiency, hyperparathyroidism, and hypothyroidism. Hypermagnesemia mainly affects the cardiovascular and nervous systems and does so in a dose-dependent manner. The initial effects of hypermagnesemia are nonspecific and can occur at levels of 3 to 4 mEq/L.[9] These include nausea, vomiting, cutaneous vasodilation, and feeling hot all over. As the serum magnesium level increases to 4 to 6 mEq/L, deep tendon reflexes are lost and electrocardiographic changes occur, including PR interval prolongation and QRS interval prolongation. Hypotension, bradycardia, and further conduction abnormalities can occur at serum magnesium levels of 6 to 10 mEq/L. As the level continues to rise to 10 to 15 mEq/L, complete heart block, respiratory depression, and coma can occur. Asystolic arrest is a frequent finding with magnesium levels of greater than 15 mEq/L.[13,23-25] Additionally, the packaging specifically states that one should not use if they have kidney disease.
If you are diabetic, have thyroid problems, adrenal issues, and such in which will affect the kidneys in their ability to clear, then one should not use this product unless they consult their physician. One should also consult their physician if they have a condition in which might affect their kidney's but they haven't necessarily developed actual problems with the kidneys as of yet. This is called latent disease.
Additionally, if one is taking magnesium supplements, or other products which contain magnesium, then one should be informed.
