Antacid medications are commonly used to relieve heartburn, acid reflux, indigestion, and gas. Many popular brands like Mylanta, Maalox, and Gaviscon contain a combination of aluminum, magnesium, simethicone, and sodium carboxymethyl cellulose (CMC). Each ingredient serves a specific purpose — let’s break it down.
1. Aluminium Hydroxide:
- Neutralizes excess stomach acid to reduce burning and discomfort
- Effective for heartburn, acid reflux, and upset stomach
- Side effect: May cause constipation, especially in higher doses
2. Magnesium Hydroxide:
- Also neutralizes stomach acid but acts more quickly than aluminum
- Has a mild laxative effect, which helps offset aluminum’s constipating properties
- Provides fast relief for acid-related issues
3. Simethicone:
- Breaks apart gas bubbles in the digestive tract
- Relieves bloating, gas pains, and pressure
- Does not affect acid, but helps with gas-related symptoms
4. Sodium Carboxymethyl Cellulose (Sodium CMC):
- A thickening agent is often used in liquid antacids
- Improves the texture and helps suspend ingredients evenly
- It may also provide a soothing coating to the stomach lining, enhancing comfort
Common Uses for This Combination:
- Acid reflux (GERD)
- Heartburn and indigestion
- Gas and bloating
- Mild gastritis or stomach irritation
Typical Brands Containing This Combo:
- Mylanta
- Maalox
- Gaviscon (varies by region)
These are available over-the-counter in tablet or liquid form and are often used as needed after meals or before bed.
Possible Side Effects:
- Constipation (aluminum)
- Diarrhea (magnesium)
- Mild nausea or upset stomach
- Allergic reactions (very rare — rash, swelling, difficulty breathing)
Precautions and Warnings:
- Talk to your doctor if you have kidney disease, as magnesium and aluminum can accumulate in the body
- Check sodium content if you’re on a low-sodium diet
- Avoid prolonged use without medical advice — it may mask more serious conditions like ulcers or GERD
- Not recommended during pregnancy or breastfeeding unless approved by a healthcare provider
Conclusion
This combination of aluminium hydroxide, magnesium hydroxide, simethicone, and sodium CMC provides balanced, fast-acting relief from a wide range of stomach issues — from acid reflux to bloating.
However, it’s important to follow dosage instructions and consult your healthcare provider if symptoms persist or worsen.
