Magnesium Oxide

Magnesium Oxide

What Is Magnesium Oxide?

Magnesium oxide is a mineral supplement used to treat or prevent low levels of magnesium in the blood.

Magnesium is important for many systems in the body, but it is especially vital for healthy muscles and bones.

Some people use magnesium oxide to relieve heartburn or indigestion. The supplement may also be used short-term as a laxative.

The supplement is available over-the-counter (OTC) without a prescription.

Magnesium Oxide and Anxiety

Some people take magnesium oxide in an attempt to relieve symptoms of anxiety. There have been a few reports that low levels of magnesium may be associated with anxiety.

However, other research has shown no link between improved symptoms and taking magnesium oxide.

Pregnancy and Magnesium Oxide

It's not known whether magnesium oxide will harm an unborn baby. You shouldn't take this supplement without first talking to your doctor if you are pregnant or plan to become pregnant.

It is also not known whether magnesium oxide harms a nursing baby. Talk with your doctor before taking magnesium oxide while breastfeeding.

What happens if I miss a dose?

Since magnesium oxide is sometimes used when needed, you may not be on a dosing schedule. If you are on a schedule, take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

Side Effects

Stomach upset and diarrhea may occur. Taking this product with a meal helps to reduce these effects. If either of these effects persist or worsen, tell your doctor or pharmacist promptly.

If your doctor has directed you to use this medication, remember that he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

Other Possible Uses of Magnesium Oxide

Aside from increasing magnesium levels, magnesium oxide has also been used to help ease the following conditions:13

• Constipation: The low absorption rate of magnesium oxide gives it a strong laxative property, which can induce bowel movement.

• Acid reflux: Magnesium oxide acts as an antacid that can help alleviate acid reflux.

• Indigestion: Similar to acid reflux, indigestion is also caused by excess acid, which can be neutralized by magnesium oxide.

What other information should I know?

If this medicine has been prescribed for you, keep all appointments with your doctor so that your response to magnesium can be checked.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
