What does Mylanta do to the body?

4 min read

Mylanta is the #1 doctor-recommended liquid antacid brand, known for providing rapid relief for digestive discomfort. By neutralizing stomach acid and breaking down gas bubbles, the medication offers quick symptomatic relief. So, what does Mylanta do to the body to achieve this fast-acting effect and how does it work?

Quick Summary

Mylanta is an over-the-counter medication that combines antacids like aluminum and magnesium hydroxide to neutralize stomach acid with simethicone to break up gas bubbles. This provides quick, multi-symptom relief for heartburn, acid indigestion, and bloating, working on contact rather than preventing future acid production.

Key Points

  • Mechanism of Action: Mylanta uses a combination of aluminum hydroxide and magnesium hydroxide to neutralize existing stomach acid for rapid relief.

  • Gas Relief: Simethicone, an anti-foaming agent, is also included in many Mylanta formulations to help break up trapped gas bubbles that cause bloating and pressure.

  • Fast-Acting but Short-Lived: It works within minutes to provide relief but its effects are short-lived, lasting about an hour, compared to longer-lasting medications.

  • Balancing Side Effects: The magnesium in Mylanta can cause diarrhea, while the aluminum can cause constipation, with the combination often balancing each other out.

  • Short-Term Use Recommended: Mylanta is intended for occasional, short-term use, and prolonged daily use should be discussed with a doctor to rule out more serious issues.

  • Interference with Absorption: Antacids can prevent the absorption of other medications, so it's important to schedule them appropriately and not take them together.

The Mechanism of Mylanta: How it Works in Your Body

At its core, Mylanta is a combination product designed to address multiple digestive discomforts simultaneously. Its primary actions involve neutralizing stomach acid and relieving gas symptoms through its unique blend of active ingredients. The typical maximum-strength liquid formulations contain aluminum hydroxide, magnesium hydroxide, and simethicone, each playing a distinct role in providing relief.

Neutralizing Stomach Acid with Antacids

  • Aluminum Hydroxide: This is an antacid that works by reacting with the hydrochloric acid in your stomach to form aluminum salts and water, thereby reducing the stomach's acidity. By raising the stomach's pH, it helps to alleviate the burning sensation of heartburn and acid indigestion. A known side effect of aluminum hydroxide is constipation, which is a common issue with many aluminum-based antacids.
  • Magnesium Hydroxide: Acting in concert with aluminum hydroxide, magnesium hydroxide also neutralizes stomach acid. However, its distinct effect is that it can act as a laxative due to its osmotic properties, drawing water into the intestines. This often counteracts the constipating effect of the aluminum hydroxide, helping to balance the digestive system's motility.

Relieving Gas with Simethicone

  • Simethicone: This ingredient is not an antacid but an anti-foaming agent specifically for gas relief. Simethicone works by changing the surface tension of gas bubbles in the stomach and intestines, causing them to combine into larger, more easily passable bubbles. This helps to relieve painful bloating, pressure, and belching associated with excess gas. Because simethicone is not absorbed into the body, it has very few side effects.

The combination of these ingredients allows Mylanta to provide rapid, multi-symptom relief by tackling both the acid and gas components of digestive upset at the source.

What Conditions Does Mylanta Treat?

Because of its multi-pronged mechanism, Mylanta is effective for a range of common gastrointestinal complaints. These include:

  • Heartburn: The burning sensation caused by stomach acid splashing back into the esophagus.
  • Acid Indigestion: A general term for stomach discomfort after eating that involves bloating, burping, or a sour taste.
  • Sour Stomach: A general term for an upset stomach caused by excess acid.
  • Gas: Painful pressure, bloating, and discomfort from trapped gas bubbles in the digestive tract.

Using Mylanta Safely and Effectively

While Mylanta is an over-the-counter medication, it is important to use it properly to avoid side effects and potential complications. Liquid formulations and chewable tablets have their own specific dosing instructions. It is important to follow the instructions provided by a healthcare professional or on the product packaging.

Short-Term vs. Long-Term Use

Antacids like Mylanta are intended for occasional or short-term use. If you find yourself needing to take Mylanta daily for more than two weeks, you should consult a healthcare provider. Chronic heartburn or indigestion may be a sign of a more serious underlying condition, such as GERD, which requires a different treatment approach.

Potential Drug Interactions

Mylanta's active ingredients can interfere with the absorption of other medications. The antacids can bind to minerals like iron and certain antibiotics (tetracyclines, quinolones), reducing their effectiveness. It is generally recommended to avoid taking other medications within a specific timeframe of taking Mylanta, as advised by a healthcare professional or product instructions.

Side Effects

Common side effects are often related to the digestive system and are a direct result of the active ingredients.

  • Diarrhea (from magnesium hydroxide)
  • Constipation (from aluminum hydroxide)
  • Nausea or stomach cramps

Serious side effects are rare but can occur, especially with prolonged, excessive use or in individuals with kidney problems. These include:

  • High magnesium levels, causing confusion, muscle weakness, and irregular heartbeat.
  • High aluminum levels, causing nervous system or bone problems.
  • Low phosphate levels, with symptoms like tiredness and muscle weakness.

Potential Downside Short duration; can cause diarrhea/constipation; potential for kidney issues with overuse May cause constipation; potential for acid rebound; unsuitable for kidney disease Slower onset of action compared to antacids Delayed onset of action; potential long-term side effects like bone weakening and low magnesium

Conclusion

Mylanta is an effective and fast-acting over-the-counter medication designed for the temporary relief of heartburn, acid indigestion, and gas. It works on the body by neutralizing existing stomach acid and breaking up gas bubbles through its combination of antacid and anti-foaming agents. Its immediate action makes it a suitable choice for occasional, on-demand relief. However, it is not a long-term solution for chronic digestive problems, and daily use is not recommended without medical supervision. Users should be mindful of potential side effects, especially if they have kidney issues or are taking other medications that could interact with the antacids. Always consult a healthcare professional for persistent symptoms to ensure there is no underlying medical condition.

Frequently Asked Questions

Mylanta's antacid components, aluminum and magnesium hydroxide, start neutralizing stomach acid on contact, providing relief within minutes of taking it.

Mylanta is formulated to address both. The aluminum and magnesium hydroxide neutralize stomach acid for heartburn and indigestion, while the simethicone acts as an anti-gas agent to relieve bloating and pressure.

Mylanta is intended for occasional use. Long-term daily use is not recommended and should only be done under a doctor's supervision, as it may mask symptoms of a more serious underlying condition.

The most common side effects are digestive issues. The magnesium can cause diarrhea, while the aluminum can cause constipation. Other mild side effects can include nausea or upset stomach.

Excessive use or overdose, especially with underlying kidney problems, can lead to serious complications. These include electrolyte imbalances like high magnesium or aluminum levels, which can affect the nervous system and heart.

Yes, Mylanta can interfere with the absorption of many other drugs, including some antibiotics, heart medications, and iron supplements. Consult a pharmacist or doctor to determine appropriate timing for doses.

Mylanta typically contains both antacids (aluminum/magnesium hydroxide) and an anti-gas agent (simethicone), whereas Tums contains only the antacid calcium carbonate. Mylanta is therefore better suited for individuals with both heartburn and gas.
