Mylanta is a brand of over-the-counter drugs for digestive problems, manufactured by Infirst Healthcare USA under license from McNeil Consumer Healthcare, a division of Johnson & Johnson (formerly Pfizer since 2007 following its acquisition). It includes several different products intended to treat heartburn and bloating.

Mylanta Maximum Strength[edit]

Mylanta Maximum Strength is an antacid, used for the treatment of heartburn, acid reflux, and gastroesophageal reflux disease (also known as GERD).


Mylanta Maximum Strength liquid contains the following active ingredients per 10ml:

Other, non-active ingredients include benzyl alcohol, flavors, glycerin, microcrystalline cellulose, purified water, sodium carbonate, sodium carboxymethylcellulose, sorbitol, sucralose, and xanthan gum.[1]

Treatment uses and directions[edit]

Mylanta is used for the treatment of heartburn, acid indigestion, dyspepsia, bloating, gas, acid reflux, and GERD. Mylanta should not be taken by individuals under the age of 12 unless recommended by a doctor. Individuals 12 and older should take between two to four 5ml spoonfuls at the onset of symptoms. Ideally, Mylanta should be taken between meals or just before bed. Administer doses every four to six hours but do not exceed 4 doses in a 24 hours period. Pregnant women should consult a doctor before taking Mylanta.[2]

Warning and side effects[edit]

Although Mylanta usually does not produce serious side effects in most individuals, there are possible side effects to be aware of. Mylanta should not be taken by individuals who have existing kidney issues. Prolonged or excessive use of Mylanta can result in damage to the kidneys, decreased levels of phosphate in the body, dizziness, and fainting spells. Less serious side effects of Mylanta include nausea, constipation, diarrhea, and headaches . The development of a rash, swelling or itchiness that affects the mouth, tongue, throat, or cheeks, dizziness, and trouble breathing are signs of an allergic reaction and should be treated immediately by a medical professional.

Mylanta may interact with certain medications. Individuals who are taking prescription drugs should consult their doctor before taking Mylanta and should not adjust the dosage of their prescription unless directed to by a doctor. Mylanta can hinder the absorption of the following medicines: digoxin, iron, tetracycline, antibiotics, and ciprofloxacin .

If Mylanta is taken on a frequent basis, usually longer than two weeks at maximum dosage, it could result in stomach acidity issues. In order to compensate for the constant neutralized state inside the stomach, the cells in the stomach lining begin to secrete more acid which results in higher than normal acid levels.

Recall and availability[edit]

In November 2010 Mylanta was voluntarily recalled[3] due to what is described as some labelling concerns. According to sources within the company at that time, these concerns stemmed from the fact that small traces of alcohol were found in the flavoring agents of the liquid version of the antacid which was not disclosed on the labelling itself, and that the problem would be rectified "shortly". Generic liquid antacids comparable to Mylanta are now available (e.g., under the brand name "equaline"[4] among others).

Mylanta was reintroduced to the market in 2016.[5]
