Magnesium is a naturally occurring mineral. Magnesium is important for many systems in the body, especially the muscles and nerves.

Chloromag is used to treat or prevent magnesium deficiency (lack of natural magnesium in the body).

Chloromag may also be used for purposes not listed in this medication guide.

Before using Chloromag, tell your doctor about all your medical conditions or allergies, all medicines you use, and if you are pregnant or breast-feeding.

Your doctor may check your kidney function before you start using Chloromag.

Chloromag is given as an infusion into a vein. A healthcare provider will give you this injection.

You may be given other medications to help prevent serious side effects or allergic reaction.

Your breathing and blood pressure will be watched closely during and after each injection.

You may need frequent medical tests. Even if you have no symptoms, tests can help your doctor determine if this medicine is effective.

You should not be treated with Chloromag if you are allergic to it, or if you have:

• kidney disease; or

• severe heart disease.

Before you receive Chloromag, tell your doctor about all your medical conditions or allergies, and if you are pregnant or breast-feeding.

Because you will receive Chloromag in a clinical setting, you are not likely to miss a dose.

Since Chloromag is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.

Follow your doctor's instructions about any restrictions on food, beverages, or activity.

Get emergency medical help if you have signs of an allergic reaction: hives; severe dizziness, difficult breathing; swelling of your face, lips, tongue, or throat.

Tell your caregivers right away if you have:

• a light-headed feeling, like you might pass out;

• warmth, sweating, or feeling cold;

• weak or shallow breathing; or

• tingly feeling.

Common side effects of Chloromag may include:

• redness in your face or neck.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Other drugs may affect Chloromag, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.
