Milk of Magnesia – What It Is and How It Works
Milk of magnesia is a liquid medicine that contains magnesium hydroxide. It works two ways: as an antacid that neutralizes stomach acid, and as a laxative that draws water into the intestines to ease constipation. Because it does both jobs, it’s a go‑to option for many people who need quick relief.
When to Use Milk of Magnesia
If you feel heartburn after a big meal, a dose of milk of magnesia can calm the burning feeling within minutes. It also helps when you’re bloated or have an upset stomach caused by too much acid. For constipation, the same product adds moisture to your stool, making it easier to pass. Adults usually take 30‑60 mL (about 2‑4 teaspoons) once or twice a day. Kids 2‑12 years old can use a smaller amount, typically 15‑30 mL, but always follow the label or your doctor’s advice.
Safety Tips & Common Side Effects
Milk of magnesia is safe for most people, but it can cause diarrhea if you take more than recommended. That happens because too much water ends up in your bowels. Some folks feel a mild stomach cramp or a temporary metallic taste. If you have kidney disease, heart failure, or are on certain medications like antibiotics or blood pressure pills, check with a healthcare professional before using it.
Store the bottle at room temperature and keep the cap tightly sealed. Shake it gently before each use so the magnesium stays evenly mixed. Don’t use it for longer than a week without talking to a doctor; persistent constipation could signal an underlying problem.
When you’re buying milk of magnesia, look for the brand that lists “magnesium hydroxide” as the active ingredient. The concentration is usually 8 % or 16 %—the higher strength works faster but also raises the chance of side effects, so start low and see how you feel.
If you miss a dose, just take it when you remember; don’t double up. For heartburn, take it after meals or when symptoms start. For constipation, it’s best to take it at night so the laxative effect happens while you’re sleeping.
Always read the label for any extra ingredients like flavorings or sugars, especially if you’re watching your calorie intake or have a sugar allergy. Some flavored versions taste like orange or lemon, which can make the experience more pleasant.
In short, milk of magnesia is a versatile, over‑the‑counter remedy that can soothe acid‑related discomfort and clear up constipation. Use the right dose, watch for diarrhea, and talk to a healthcare provider if you have serious health conditions. With these simple steps, you’ll get the relief you need without hassle.
