Milk of Magnesia is a trusted remedy for constipation and heartburn. Getting the Milk of Magnesia dosage right is key to safe, effective relief.
This article breaks down how to use it properly, with clear, simple guidance. Let’s explore dosages, precautions, and tips for best results.
Understanding Milk of Magnesia
Milk of Magnesia is a liquid or tablet containing magnesium hydroxide. It acts as a laxative for constipation and an antacid for heartburn. Available over the counter, it’s widely used for quick relief.
The liquid form is most common, but tablets offer convenience. Both require careful dosing to avoid side effects. Knowing its purpose helps you use it correctly.
How Milk of Magnesia Works
As a laxative, it pulls water into the intestines. This softens stool and triggers bowel movements. Relief usually comes within 30 minutes to 6 hours.
As an antacid, it neutralizes stomach acid. This eases heartburn or indigestion fast, often in minutes. Proper Milk of Magnesia dosage ensures these benefits without issues.
Recommended Milk of Magnesia Dosage
Dosage depends on age, purpose, and product form. Always check the label or consult a doctor. The amounts differ for laxative and antacid use.
Adults typically take 30–60 mL (2–4 tablespoons) as a laxative. For heartburn, 5–15 mL (1–3 teaspoons) up to four times daily works. Never go over the stated dose.
Dosage by Age
- Adults (12+): 30–60 mL (laxative) or 5–15 mL (antacid).
- Children 6–11: 15–30 mL (laxative) or 5 mL (antacid).
- Children under 6: Doctor’s approval needed.
- Infants: Avoid unless prescribed.
How to Take It Safely
Shake the liquid well before use. Measure with a medical spoon or cup, not a kitchen spoon. Drinking a full glass of water afterward aids effectiveness.
Take laxative doses at bedtime for morning relief. For heartburn, use as needed, but don’t exceed four antacid doses daily. Avoid taking it with food to prevent interactions.
Tailoring Dosage for Your Needs
For occasional constipation, one dose is often enough. Chronic issues may need a doctor’s guidance. Overuse can cause problems, so stick to recommendations.
Heartburn relief often requires smaller, repeated doses. If symptoms persist beyond a few days, seek medical advice. Proper Milk of Magnesia dosage avoids complications.
Special Considerations
Some groups need extra care with Milk of Magnesia. Pregnant or breastfeeding women should check with a doctor. Those with kidney problems or on magnesium-restricted diets require caution.
Older adults may experience stronger side effects. Start with a lower dose, like 15–30 mL for constipation. Always consult a healthcare provider if unsure.
Potential Side Effects
Milk of Magnesia is safe when used as directed. Common side effects include mild diarrhea or stomach cramps. These typically fade quickly.
Overuse may lead to rare issues like high magnesium levels. This can cause dizziness or heart irregularities, especially in kidney patients. Seek help if these occur.
Drug Interactions
Milk of Magnesia can interfere with other medications. It may reduce the absorption of antibiotics, heart drugs, or vitamins. Take it 2 hours before or after other medicines.
List all your medications for your doctor. This helps avoid interactions that could lower drug effectiveness or cause side effects.

Tips for Proper Use
Use a proper measuring tool for accuracy. Drink plenty of water to support the laxative effect. Avoid long-term use without medical advice.

Safe Use Tips:
- Measure doses precisely.
- Stay hydrated.
- Don’t use daily without a doctor’s okay.
- Watch for drug interactions.
When to Avoid It
Avoid Milk of Magnesia if you have kidney disease or severe stomach pain. These conditions can worsen with use. Allergic reactions are rare but possible.
Stop use if you notice rash, swelling, or breathing issues. Seek medical help immediately. Always read warnings on the label.
Overdose Warning Signs
Taking too much can cause serious issues. Symptoms include severe diarrhea, dehydration, or muscle weakness. High magnesium levels are uncommon but dangerous.
If you suspect an overdose, contact a doctor or poison control right away. Quick action prevents complications, especially for vulnerable groups.
Alternatives to Milk of Magnesia
If Milk of Magnesia isn’t right for you, try other options. Fiber supplements like Metamucil help constipation. Antacids like Rolaids work for heartburn.
Lifestyle changes, like eating more fiber or exercising, also help. A doctor can suggest the best alternative for your situation.
Long-Term Use Risks
Daily use isn’t recommended. Long-term laxative use may cause bowel dependency. This makes natural bowel movements harder over time.
For ongoing constipation or heartburn, see a doctor. They may recommend diet changes or other treatments to avoid reliance on Milk of Magnesia.
Common Misconceptions
Some believe Milk of Magnesia is unsafe for occasional use. When dosed correctly, it’s effective and low-risk. Problems come from misuse, not the product itself.
Another myth is that it’s only for seniors. People of all ages can use it with proper Milk of Magnesia dosage. Education clears up these misunderstandings.
Emotional and Practical Benefits
Constipation or heartburn can feel draining. Milk of Magnesia offers fast relief, improving comfort and daily life. Knowing how to dose it right boosts confidence.
If dosing feels confusing, ask a pharmacist. They can explain clearly. You’re not alone in learning to use this remedy.
Storage and Handling
Store Milk of Magnesia in a cool, dry place. Avoid humid areas like bathrooms. Check the expiration date and discard if expired.
Shake the bottle well before pouring. This ensures the magnesium hydroxide is evenly distributed. Proper storage keeps it effective.
When to Talk to a Doctor
If symptoms don’t improve, consult a doctor. Ongoing constipation or heartburn could point to bigger issues. A professional can adjust your Milk of Magnesia dosage or run tests.
Share your full medication list with your doctor. This prevents interactions and ensures safe use. Open communication leads to better outcomes.
Busting Myths
Some think Milk of Magnesia causes instant dependency. Short-term use is safe and doesn’t lead to reliance. Long-term use is what needs caution.
Others worry it’s harmful for kids. With proper dosing and doctor approval, it’s safe for children over 6. Facts dispel these concerns.
Practical Scenarios
For travel-related constipation, a single dose often helps. Take it at night for morning relief. Keep a small bottle handy for emergencies.
For occasional heartburn, a teaspoon or two works fast. Avoid overuse to prevent side effects. Knowing when to use it makes life easier.
