Depends on symptoms: The way to recognize mag overdose is blood work that shows increase in values. If the "overdose" caused heart rhythm problems that caused a cardiac arrest, then long term problems are possible. But if "overdose" means increase in blood level, then it is not important. Usually after Magnesium Sulfate infusion, levels in blood go up before they normalize by moving out of blood into storage in cells.
