Side-Effects of Antacids

The first thing that we go to when we suffer from acidity are antacids. No doubt they relieve us but the

side-effects of antacids

should also be taken into consideration. Most people may not experience an side-effects upon using antacids, but not everyone’s body constituency is the same. Also, other medications that are simultaneously taken can conflict with the antacids creating unwanted side-effects.

Side-Effects of Antacids:

People who suffer from heartburns and reflux problems take antacids for relief. The antacids suppress the stomach acid creating the relief, but the actual problem of the reflux is not addressed. Also, the suppression of stomach acids can lead to a problem with the absorption of nutrients leading to other health issues.

  • Another reason is their composition. Antacids usually contain chemicals of aluminum, magnesium, sodium bicarbonate and calcium that can also lead to some unwanted side-effects in the body.
  • The usual side-effects that one would normally experience are chalky taste, mild constipation or diarrhea, stomach cramps and thirst. Let us look at what the chemicals in them can lead to.


The chemical aluminium can cause sever constipation, weight loss, joint swelling, loss of appetite, lack of interest or moodiness, aching bones and muscle weakness. It can also lead to


(reduction of phosphate levels in the blood) and


(softening of bones due to lack of phosphorus).


Calcium based antacids can cause pain while urinating, fatigue, restlessness, headaches, loss of appetite, moodiness, inability to pass urine and nausea. They can also lead to Burnett’s syndrome which can further cause a kidney failure that could be fatal.


Magnesium based antacids lead to fatigue, unexpected weight loss, nausea, pain while urinating, arrhythmia (irregular heartbeat), feeling light-headed and muscle weakness. Along with the cardiovascular problems, neurological complications are also a possibility.

Sodium Bicarbonate:

Sodium bicarbonate based antacids cause problems like continual headache, discolored stools, thirst, slow breathing, loss of appetite, restlessness, frequent urination, problems with taste and stomach cramps. It can also lead to

It is important to note that no antacid should be used for more than 14 days at a stretch. This is to avoid any of the above mentioned unwanted

side-effects of antacids
