Milk of magnesia is a popular over-the-counter medication that helps with constipation, heartburn, and upset stomach. It works by neutralizing stomach acid and increasing the water content in the intestines. Milk of magnesia is also known as magnesium hydroxide, which is the active ingredient.
You can find milk of magnesia in liquid and tablet form, and it is generally safe for most people to use. However, it is important to follow the recommended dosage and talk to a healthcare provider before taking it if you have any underlying medical conditions or are using other medications. Moreover, milk of magnesia should not be used as a long-term solution for constipation or other digestive issues without consulting a healthcare provider first.
Chemical Composition
Milk of Magnesia is a popular over-the-counter medication used to relieve constipation, heartburn, and indigestion. It is a suspension of magnesium hydroxide in water, with a milky appearance and a slightly sweet taste.
Active Ingredient

Magnesium hydroxide works by neutralizing stomach acid and increasing water content in the intestines, which helps to soften and bulk up stool, making it easier to pass.
Additional Components
Apart from magnesium hydroxide, Milk of Magnesia may also contain additional components such as flavourings, preservatives, and stabilizers. These components may vary depending on the manufacturer, but they are generally safe and do not affect the medication’s efficacy.
It is important to note that Milk of Magnesia should be used only as directed and under the supervision of a healthcare professional. Overuse or misuse of this medication may lead to adverse effects such as diarrhoea, dehydration, and electrolyte imbalances.

Medical Uses
Milk of Magnesia is a common over-the-counter medication that is used for a variety of medical purposes. This section will outline two of its primary uses: as a laxative and as an antacid.
Laxative Effects
Milk of Magnesia is commonly used as a laxative to relieve constipation. It works by drawing water into the intestines, which softens the stool and makes it easier to pass. This medication is especially useful for people who suffer from chronic constipation or who have difficulty passing stool due to medical conditions such as irritable bowel syndrome.
When using Milk of Magnesia as a laxative, it is important to follow the instructions on the label carefully. Overuse of this medication can lead to dehydration, electrolyte imbalances, and other complications. Patients should also be aware that it may take several hours for the medication to take effect, so it should be taken well in advance of any planned activity.
Antacid Properties
In addition to its laxative effects, Milk of Magnesia is also commonly used as an antacid to relieve heartburn and other symptoms of acid reflux. This medication works by neutralizing stomach acid, which can help to reduce irritation and inflammation in the oesophagus.
When using Milk of Magnesia as an antacid, patients should be aware that it may interact with other medications. It is important to talk to a healthcare provider before using this medication if you are taking any other prescription or over-the-counter drugs. Patients should also be aware that overuse of this medication can lead to complications such as diarrhoea and electrolyte imbalances.
Dosage and Administration
