FAQs about digestive health medicines

Which medicines are used for heartburn and indigestion?

Antacids such as Rennie and alginate products such as Gaviscon are common first choices for occasional symptoms. For heartburn that keeps returning, a medicine that reduces acid production, such as omeprazole, may be suggested. A pharmacist can advise which type fits your symptoms.

How long can I take omeprazole without seeing a doctor?

Pharmacy-available omeprazole is intended for short-term use in adults with frequent heartburn, and it follows a set course described in the product leaflet. If symptoms return or do not improve, speak to your GP rather than continuing on your own.

When should I avoid loperamide?

Loperamide is meant for short bouts of simple diarrhea. Avoid it, and seek medical advice if you have blood in your stool, a high temperature, severe stomach pain, or diarrhea after antibiotics. It is also not suitable for young children.

Do I need rehydration salts for every case of diarrhoea?

Not always, but they are helpful when you are losing a lot of fluid or when you are very young, older, or otherwise at risk of dehydration. Always mix the sachet exactly as the instructions say, using the correct amount of water.

When should I see a doctor about stomach symptoms?

Seek medical advice promptly if you have difficulty swallowing, unexplained weight loss, vomiting blood, black or bloody stools, or symptoms that last several weeks. These can signal a problem that needs proper assessment rather than self-treatment.
