About magnesium hydroxide

Overview

This medication is used for a short time to treat occasional constipation. It is a laxative (osmotic-type) that is thought to work by drawing water into the intestines, an effect that helps to cause movement of the intestines.

This medication is also used to treat symptoms caused by too much stomach acid such as heartburn, upset stomach, or indigestion. It is an antacid that works by lowering the amount of acid in the stomach.

How to use

Take this product by mouth as directed. For the chewable form, chew thoroughly before swallowing. For the liquid form, shake the bottle well before each dose. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. If you are taking this medication for constipation, drink a full glass of water (8 ounces or 240 milliliters) with each dose. Follow all directions on the product package, or use as directed by your doctor. If you have any questions, ask your doctor or pharmacist.

Dosage is based on your medical condition and response to treatment.

Extended use or overuse of this medication for constipation may result in dependence on laxatives and ongoing constipation. Overuse may also cause persistent diarrhea, loss of too much body water (dehydration), and mineral imbalances (e.g., high magnesium).

Tell your doctor if your condition persists or worsens. For constipation problems, it may take 30 minutes to 6 hours to produce a bowel movement. Tell your doctor if this product does not produce a bowel movement, if you need to use this medication or other laxative products regularly for more than 1 week, or if you have rectal bleeding. For stomach acid problems, do not take the maximum dose of this medication for more than 2 weeks unless directed by your doctor. If you think you may have a serious medical problem, seek immediate medical attention.

Side effects

Diarrhea may occur. If this effect persists or worsens, 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.

Tell your doctor right away if any of these unlikely but serious side effects occur: symptoms of high magnesium levels (e.g., muscle weakness, slow/irregular heartbeat, slow/shallow breathing, mental/mood changes such as confusion), symptoms of dehydration (e.g., decreased urination, dizziness, extreme thirst, very dry mouth), stomach/abdominal pain, bloody stools, rectal bleeding.

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.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Notes:

Keep all regular medical and laboratory appointments.

Lifestyle changes such as regular exercise and diet changes (including drinking enough water, eating a proper diet with fiber-rich foods such as bran, fresh fruits/vegetables) may prevent or relieve constipation.

Lifestyle changes such as stress reduction programs, stopping smoking, limiting alcohol, and diet changes (e.g., avoiding caffeine/certain spices) may help to reduce heartburn and other stomach acid problems.
