Overview
Magnesium bolus, particularly magnesium sulfate, is often used during pregnancy to manage specific conditions such as preeclampsia and to prevent preterm labor. It is generally considered safe when administered under medical supervision, but there are important considerations regarding its use.
Benefits and Uses
- Preeclampsia Management: Magnesium sulfate is commonly used to prevent and treat seizures in women with preeclampsia, a condition characterized by high blood pressure and potential organ damage during pregnancy. It helps stabilize blood pressure and reduce the risk of eclamptic seizures.Magnesium supplementation in pregnancy - PMCMagnesium is an essential mineral ... low intakes of magnesium.

Dosage and Administration
- Bolus Dose: A typical bolus dose of magnesium sulfate is 4-6 grams administered intravenously over 15-30 minutes, followed by a continuous infusion. This should be carefully monitored to avoid toxicity.A randomized trial comparing the pharmacology of magnesium sulfate when used to treat severe preeclampsia with serial intravenous boluses versus a continuous intravenous infusion | BMC Pregnancy and Childbirth | Full TextBackground Magnesium sulfate is the preferred pharmacological intervention for the prevention and treatment of eclamptic seizures in pregnancy.
