Magnesium Sulfate is Used for:

Treating low magnesium levels and maintaining the proper amount of magnesium in the body when used as part of intravenous (IV) feedings (eg, total parenteral nutrition [TPN]). It is also used in pregnant women to control seizures due to certain complications of pregnancy (eg, severe toxemia) and to control high blood pressure, severe brain function problems (encephalopathy), and seizures in children who have sudden, severe inflammation of the kidneys (acute nephritis).magnesium-sulfate-relaxes-spasms

Magnesium sulfate is a mineral. It works by replacing magnesium in patients who have low magnesium levels in the body due to illness or treatment with certain medicines. Magnesium sulfate may also be used to treat seizures by decreasing certain nerve impulses to muscles.

Magnesium sulfate is an inorganic salt (chemical compound) containing magnesium, sulfur and oxygen, with the formula MgSO4. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO4·7H2O), commonly called Epsom salt, taking its name from a bitter saline spring in Epsom in Surrey, England, where the salt was produced from the springs that arise where the porous chalk of the North Downs meets non-porous London clay. The monohydrate, MgSO4·H2O is found as the mineral kieserite. The overall global annual usage in the mid-1970s of the monohydrate was 2.3 million tons, of which the majority was used in agriculture.

Anhydrous magnesium sulfate is used as a drying agent. The anhydrous form is hygroscopic (readily absorbs water from the air) and is therefore difficult to weigh accurately; the hydrate is often preferred when preparing solutions (for example, in medical preparations). Epsom salt has been traditionally used as a component of bath salts. Epsom salt can also be used as a beauty product. Athletes use it to soothe sore muscles, while gardeners use it to improve crops. It has a variety of other uses: for example, Epsom salt is also effective in the removal of splinters.

It is on the WHO Model List of Essential Medicines, the most important medications needed in a basic health system.
