What is the therapeutic magnesium level?

The therapeutic magnesium level, particularly in the context of obstetrics, is generally considered to be within the range of 5-9 mg/dL. This range is used in the management of conditions like preeclampsia and eclampsia, where magnesium sulfate is administered as a neuroprotective agent to prevent seizures. The therapeutic levels aim to achieve the desired effects without causing toxicity, which can occur if levels rise significantly above this range. Specifically, levels above 9 mg/dL can increase the risk of side effects, including respiratory depression and cardiovascular problems. Thus, maintaining magnesium levels within the 5-9 mg/dL range is crucial for effective treatment while minimizing potential adverse effects.
