Understanding Milk of Magnesia Dosage: A Guide to Safe and Effective Use

Milk of Magnesia, a suspension of magnesium hydroxide, is a widely used over-the-counter (OTC) medication for treating heartburn, indigestion, and constipation. However, to ensure safe and effective use, it's crucial to understand the proper dosage and administration guidelines. In this article, we will delve into the details of Milk of Magnesia dosage, its uses, and potential side effects, providing you with a comprehensive guide to make informed decisions about your health.

The active ingredient in Milk of Magnesia, magnesium hydroxide, works by neutralizing stomach acid and stimulating bowel movements. While it can provide quick relief from digestive discomfort, improper use can lead to adverse effects, such as diarrhea, stomach cramps, and electrolyte imbalances. Therefore, it's essential to follow the recommended dosage and consult with a healthcare professional if you have any underlying medical conditions or take other medications.

The typical dosage of Milk of Magnesia for adults varies depending on the intended use:

  • For heartburn and indigestion: 1-2 tablespoons (15-30 mL) as needed, not to exceed 4-6 doses in 24 hours
  • For constipation: 2-4 tablespoons (30-60 mL) once or twice a day

It's essential to note that the dosage may vary depending on individual tolerance and response. Starting with a low dose and gradually increasing as needed can help minimize potential side effects.

Dosage for Children and Infants

Milk of Magnesia can be used in children, but the dosage must be adjusted according to age and weight:

Age Dosage
Infants (1-12 months) 1/4 to 1/2 teaspoon (1.25-2.5 mL) as needed
Children (1-6 years) 1/2 to 1 teaspoon (2.5-5 mL) as needed
Children (6-12 years) 1-2 teaspoons (5-10 mL) as needed

However, it's crucial to consult with a pediatrician before administering Milk of Magnesia to children, especially infants, as they may be more susceptible to side effects.
