How does this medication work? What will it do for me?
Magnesium hydroxide belongs to two groups of medications: laxatives and antacids. It is used to relieve occasional constipation and also to relieve symptoms caused by heartburn, upset stomach, or indigestion.
For constipation, magnesium hydroxide works by increasing the water content and volume of stool, which helps produce a bowel movement. For heartburn, it works by neutralizing stomach acid.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor or pharmacist has not recommended it.
How should I use this medication?
For constipation, the recommended daily dose is 6 to 8 chewable tablets, or 30 mL to 60 mL of oral suspension.
- For children aged 6 to 11 years old, the usual dose is 3 to 6 chewable tablets, or 15 mL to 30 mL of oral suspension per day.
- For children 2 to 5 years of age, the usual dose is 1 to 3 chewable tablets, or 5 mL to 15 mL of oral suspension per day.
- The dose of magnesium hydroxide for children under 2 years of age is based on weight. Talk to your doctor before giving this medication to children under 2 years of age.
For heartburn, the recommended dose for adults is 2 to 4 chewable tablets, or 5 mL to 15 mL of oral suspension up to 4 times a day. For children, the daily dose is the same as that for constipation, however the dose may be divided and given up to 4 times daily (e.g., a 6-year old may take 2 chewable tablets 3 times a day for a total of 6 tablets daily).
Shake the suspension well before taking it. Use an oral syringe or measuring spoon to measure each dose of the liquid, as it gives a more accurate measurement than household teaspoons.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor or pharmacist has recommended a dose different from the ones above, do not change the way that you are taking the medication without consulting your doctor.
