Definitive treatment of hypermagnesemia is?

Hemodialysis REF: Harrison's 17th ed chapter 346 HYPERMAGNESEMIA: TREATMENT Successful treatment of hypermagnesemia generally involves identifying and interrupting the source of magnesium and employing measures to increase magnesium clearance from the BCF. Use of magnesium-free cathaics or enemas may be helpful in clearing ingested magnesium from the gastrointestinal tract. Vigorous IV hydration should be attempted, if appropriate. Hemodialysis is effective and may be required in patients with significant renal insufficiency. Calcium, administered IV in doses of 100-200 mg over 1-2 h, has been repoed to provide temporary improvement in signs and symptoms of hypermagnesemia.
