Magnesium Glycinate Oral: Uses, Side Effects, Interactions, Pictures, Warnings & Dosing - WebMD (2024)

Uses

This medication is a mineral supplement used to prevent and treat low amounts of magnesium in the blood. Some brands are also used to treat symptoms of too much stomach acid such as stomach upset, heartburn, and acid indigestion. Magnesium is very important for the normal functioning of cells, nerves, muscles, bones, and the heart. Usually, a well-balanced diet provides normal blood levels of magnesium. However, certain situations cause your body to lose magnesium faster than you can replace it from your diet. These situations include treatment with "water pills" (diuretics such as furosemide, hydrochlorothiazide), a poor diet, alcoholism, or other medical conditions (such as severe diarrhea/vomiting, stomach/intestinal absorption problems, poorly controlled diabetes).

How to use Magnesium Glycinate 100 Mg Capsule

Take this product by mouth as directed. Follow all directions on the product package. If you have any questions, ask your doctor or pharmacist.

It is best to take magnesium supplements with a meal to reduce stomach upset and diarrhea unless otherwise directed by the product instructions or your doctor.

Take each dose with a full glass (8 ounces or 240 milliliters) of water unless your doctor directs you otherwise. Swallow extended-release capsules and delayed-release/enteric coated tablets or capsules whole. Do not crush or chew extended-release or delayed-release/enteric coated capsules or tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split extended-release tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.

If you are taking the chewable tablets, chew each tablet thoroughly before swallowing.

If you are using a liquid product, use a medication measuring device to carefully measure the dose. Do not use a household spoon because you may not get the correct dose. If you are using a suspension, shake the bottle well before each dose.

Take this medication regularly in order to get the most benefit from it. Remember to take it at the same time(s) each day. Dosage is based on your medical condition and response to treatment. Do not increase your dose or take it more often than directed on the product package or by your doctor. Too much magnesium in the blood can cause serious side effects.

Tell your doctor if symptoms of low magnesium blood levels (such as muscle cramps, tiredness, irritability, depression) last or get worse. If you think you may have a serious medical problem, get medical help right away.

Side Effects

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

If your doctor has directed you to use this medication, remember that your doctor 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, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

If you are taking a bisphosphonate (for example, alendronate), a thyroid medication (for example, levothyroxine), or a quinolone-type antibiotic (such as ciprofloxacin, levofloxacin), ask your doctor or pharmacist about how long you should wait between doses and for help finding a dosing schedule that will work with all your medications.
