Over-the-counter (OTC) drugs are drugs that can be purchased over the counter, without a prescription. These drugs are used to treat common diseases including cough, common cold and motion sickness. These drugs provide relief and treatment to patients without the need to consult a doctor.

However, it is crucial to understand the interactions of OTC drugs with the body, as there may be some side effects or ill-effects due to reaction with another drug or in some cases may lead to addiction.

In this blog, the OTC antacids will be focused upon.

Antacid is an OTC drug used to relieve discomfort from gastric reflux. It is usually taken to treat indigestion, heartburn, gastritis and various forms of ulcer. Antacids are usually weak bases, which are available  in tablet or liquid forms.

With the advancement of modern medicine, proton pump inhibitors and H2-receptor antagonists (commonly called H2 blockers) are now more widely used for these conditions in replacement of antacid. For long term, these modern medicines are considered much more effective than antacids. This is because unlike antacids, which simply neutralise the acid for a short time, these medicines work by reducing the amount of acid made by the stomach.

However, antacids still have a place. They are most commonly used to provide quick relief of symptoms caused by stomach acid. In particular, in people who get occasional bouts of mild dyspepsia or heartburn.
