 (Mg) [mag-ne´ze-um]
a chemical element, atomic number 12, atomic weight 24.312. (See Appendix 6.) Its salts are essential in nutrition, being required for the activity of many enzymes, especially those concerned with oxidative phosphorylation. It is found in the intra- and extracellular fluids and is excreted in urine and feces. The normal serum level is approximately 2 mEq/L. Magnesium deficiency causes irritability of the nervous system with tetany, vasodilation, convulsions, tremors, depression, and psychotic behavior.
Homeostasis of magnesium in extracellular fluids. The normal serum magnesium level is regulated by intestinal and renal function. Most of the body's magnesium is stored in bones, muscle, and soft tissue. From Malarkey and McMorrow, 2000.

Patient discussion about Mg

Q. Is 700 mg of seroquel too much? My husband has prescriptions for seroquel. He is to take 600 mg at bedtime. He becomes lathargic. Many times he takes and extra 100 mg of seroquel and goes into a stuper like condition. What can happen?

A. Somnolence is a well-know side effect of Seroquel, so it’s not surprising. In addition, the dosage you specified seems within normal range. However, dosage may need personal adjustment, and since making this through the net is neither successful nor responsible, I’d suggest consulting a professional (e.g. his doctor) and discuss these issues with him or her.
