ANTACIDS

Antacids are drugs that block or reduce the amount of acid that is produced in the stomach. There are many different forms of antacids; some are combination products that contain many other ingredients.


Most of the antacids usually contain one or two of the following:

  • aluminum
  • calcium or
  • magnesium

Many people use antacids to relieve a burning pain in the middle of the chest called heartburn. Heartburn may or may not be a sign of an ulcer. Ulcers are irritated areas that develop in the stomach in response to infection or increased acid production. They can be small or large in size. Pain is common with them and antacids can be used to treat the pain and prevent the ulcer from worsening. Other problems, including heart attacks can mimic the symptoms of heartburn. It is important to discuss any new symptoms with your doctor.


The most common side effects of antacids are:

  • constipation (with aluminum containing antacids)
  • diarrhea (with magnesium containing antacids)
  • increased thirst and
  • decreased appetite

Many antacids taste chalky. Drink at least one glass of water when using them. Give children antacids only when suggested by a doctor. It is especially important to use caution with the magnesium-containing medications especially if the child has kidney problems or is dehydrated. The doctor will decide if the drug is safe for the child.


Adults and elderly patients need to be careful if they take antacids too, especially if they have certain diseases. Certain medications should not be taken with antacids. It is important to check with your doctor and pharmacist before starting to take any antacid. Be sure to check with your healthcare provider if the pain or discomfort does not go away after taking the drug for several doses.
