Magnesium Sulfate Macarthys Laboratories (Magnesium Sulfate Heptahydrate)

After infusion, magnesium sulfate releases magnesium ions that act as calcium antagonists, causing vasodilation, stabilising neuronal membranes, and providing anticonvulsant effects. These actions help restore normal magnesium concentrations, supporting cardiac rhythm, neuromuscular function, and vascular tone.

The specific dose of magnesium sulfate is determined by the prescribing clinician based on the patient’s clinical condition, serum magnesium level, weight, and renal function. Dosing regimens vary for hypomagnesemia, eclampsia prophylaxis, and arrhythmia treatment.

Magnesium sulfate is commonly used in obstetric care for eclampsia prevention and treatment, and it is considered relatively safe when administered under medical supervision. However, the risk‑benefit profile should be evaluated by the treating physician, and breastfeeding mothers should discuss use with their healthcare provider.

To place an order, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including cold‑chain where applicable) and necessary import documentation.

Magnesium sulfate is the preferred intravenous source of magnesium because it provides rapid correction of serum levels and has well‑characterised pharmacodynamics. Other electrolytes such as calcium gluconate or potassium chloride address different deficiencies; magnesium sulfate uniquely offers vasodilatory and anticonvulsant properties useful in eclampsia and certain arrhythmias.

Magnesium sulfate for injection should be stored at 2‑8 °C, kept in its original container, protected from light, and must not be frozen or shaken vigorously. If a temperature excursion occurs, inspect the solution for precipitation before use.

Magnesium sulfate is administered intravenously by a qualified healthcare professional. It can be given as a slow infusion or bolus, depending on the indication and clinical protocol. Proper aseptic technique and appropriate infusion equipment are required to ensure safe delivery.

Serious risks include respiratory depression, severe hypotension, cardiac arrhythmias, hypermagnesemia leading to neuromuscular weakness, and rare anaphylactic reactions. Continuous monitoring of vital signs and serum magnesium levels is essential, especially in patients with renal impairment or cardiac disease.

Magnesium sulfate is contraindicated in patients with known hypersensitivity to the product, severe renal failure where magnesium clearance is markedly reduced, and in those receiving incompatible calcium‑containing solutions that could precipitate. Clinicians should also exercise caution in patients with existing heart block or profound hypotension.
