Maalox vs Mylanta – Ingredients & Differences

Maalox vs Mylanta: which is better?


Heartburn is associated with a burning pain in the throat or chest.

It usually happens when your stomach acid flows back into your esophagus.

Heartburn is one of the most frequent symptoms of Gastro-Oesophageal Reflux Disease.


Symptoms of heartburn include:

  • bitter taste in the mouth;
  • pain which worsens when bending over or lying down;
  • rising pain, possibly reaching the jaw;
  • a burning pain in the middle of the chest which typically occurs after eating.

Note – there are some similarities between heart attack symptoms and heartburn.

Therefore, if you have any warning signs of a heart attack or any chest pain which lasts for more than several minutes, seek immediate medical attention.


A few factors may lead to heartburn or make it feel worse, such as:

  • use of certain medicines, particularly anti-inflammatory drugs;
  • eating large food portions;
  • having GERD;
  • being obese or overweight;
  • having a condition called hiatal hernia (when the upper part of the stomach bulges through an opening in the diaphragm);
  • eating shortly before bedtime;
  • pregnancy;
  • regularly drinking alcohol, carbonated beverages, and caffeinated beverages;
  • emotional stress;
  • wearing belts and tight clothes;
  • smoking tobacco and second-hand smoking;
  • eating certain foods, like – chocolate, peppermint, onions, high-fat foods, garlic, cayenne pepper, citrus fruits, and tomato-based products.

This article reveals the differences between Maalox and Mylanta:

Maaloxis maalox the same as mylanta

It is a medication that is used to treat heartburn.

This drug is produced in Switzerland by the company Novartis.


Active ingredients:

  • aluminum hydroxide (antacid);
  • magnesium hydroxide (antacid).

The 2 substances are commonly combined in antacid mixtures.

Magnesium hydroxide may cause diarrhea, however, this effect is balanced by the effect of aluminum hydroxide which is an astringent and may cause constipation.

Inactive ingredients:

  • sorbitol;
  • saccharin sodium;
  • purified water;
  • propylparaben (in the paraben family of preservatives);
  • cellulose;
  • microcrystalline;
  • hypromellose (a semisynthetic, inert, viscoelastic polymer);
  • flavor;
  • carboxymethylcellulose sodium;
  • butylparaben.

Mylantais mylanta the same as maalox

This medication acts by neutralizing the excess acid produced in the stomach.


Active ingredients:

  • aluminum hydroxide (an inorganic compound that has aluminum);
  • magnesium hydroxide;
  • simethicone.

Inactive ingredients:

  • xanthan gum (a polysaccharide used as a food additive);
  • sucralose;
  • sorbitol;
  • sodium carbonate;
  • purified water;
  • microcrystalline cellulose;
  • glycerin (a trihydroxy alcohol with laxative properties);
  • flavors;
  • carboxymethylcellulose sodium;
  • benzyl alcohol.


Maalox is used for the relief of:acid reflux

  • heartburn;

Mechanism of Action


  • increases gastric pH;
  • neutralizes gastric acid.


  • simethicone – it prevents gas pockets in the gastrointestinal system by decreasing the surface tension of gas bubbles;
  • magnesium hydroxide – it promotes bowel evacuation by causing osmotic retention of fluid;
  • aluminum hydroxide – it neutralizes stomach hydrochloride to form AlCl3 salt plus water.

Side Effects

Possible side effects of Maalox include:

  • muscle weakness;
  • diarrhea;
  • loss of appetite;
  • unusual tiredness;
  • constipation.

Possible side effects of Mylanta include:

Bottom Line – Maalox vs Mylanta

Maalox is a mixture of two antacids – magnesium hydroxide (a fast-acting antacid) and aluminum hydroxide (a slow-acting antacid) which is used to treat upset stomach and heartburn.

Mylanta is an antacid medication that is used to promote healing of duodenal ulcers and to relieve the symptoms of excess stomach acid. It contains aluminum hydroxide, magnesium hydroxide, and simethicone.

The main difference between Mylanta and Maalox is that Mylanta contains simethicone (an anti-foaming agent that facilitates the removal of gas from the digestive tract) while Maalox does not.

In addition, these medications have different inactive ingredients and price (Mylanta is slightly cheaper).
