Taking antacids with food, alcohol and other medicines:
- It is best to take antacids with food or soon after eating because this is when you are most likely to get indigestion or heartburn.
- If taken with food, the effect of the medicine may also last longer.
- Antacids may affect how well other drugs work, so do not take other drugs within two to four hours of taking an antacid.
- You can drink alcohol while taking antacids, but alcohol can irritate your stomach and make your symptoms worse.
Antacids have some types:
- Aluminium hydroxide
- Magnesium carbonate
- Magnesium trisilicate
- Magnesium hydroxide
- Calcium carbonate
- Sodium bicarbonate
Antacids do not usually have many side effects if they are taken only occasionally and at the recommended dose. But sometimes they can cause:
- Diarrhoea or constipation
- Flatulence (wind)
- Stomach cramps
- Feeling sick or vomiting
These should pass once you stop taking the medicine. Talk to a pharmacist or your GP if they are not getting better or having trouble. You might need to switch to another medicine.
