Antacids help to treat heartburn (indigestion). They work by neutralizing the stomach acid that causes heartburn. You can buy many antacids without a prescription. Liquid forms work faster, but you may prefer tablets because they are easy to use.

This medication is used to treat the symptoms of too much stomach acid such as stomach upset, heartburn, and acid indigestion. It is also used to relieve symptoms of extra gas such as belching, bloating, and feelings of pressure/discomfort in the stomach/gut.

Nausea, constipation, diarrhea, or headache may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly. The magnesium in this product can cause diarrhea.

They can quickly relieve your symptoms for a few hours. But they do not treat the underlying cause and long-term use is not recommended. Speak to a GP if you find you need to take antacids regularly.
