## The short answer

A low-dose omeprazole 20mg pharmacy pack is intended for a defined short course. NHS advice says not to continue bought treatment beyond two weeks without seeing a GP. Check interactions and symptoms that need investigation before use.

## Understanding your options

Acid reflux occurs when stomach contents move back towards the throat, causing heartburn or a sour taste. Persistent symptoms should be assessed rather than repeatedly masked.

Lifestyle changes, antacids or alginates and acid-suppressing medicines have different roles. Some low-dose packs are available from pharmacies.

## Who may be suitable?

Share other medicines, pregnancy, persistent symptoms and any difficulty swallowing. Chest discomfort may have a cause other than reflux.

## Side effects and precautions

Check the leaflet for duration limits and interactions. Do not continue repeated short courses without discussing recurring symptoms.

## When to get help

Difficulty swallowing, unexplained weight loss, vomiting blood or black stools requires medical assessment; severe chest pain is an emergency.

For a life-threatening emergency, call 999. For urgent advice, contact the appropriate local NHS service.

## Progress and follow-up

Seek review if pharmacy treatment is not helping or symptoms occur most days.

## Questions to ask

When should I stop self-treatment and arrange a GP review?

- Does this sound like reflux or need investigation?

- Is this for quick relief or ongoing acid control?

- How long should I try it before review?

## Treatment approaches

### Prescription-strength PPI tablets

A prescribed acid-suppression plan may address persistent symptoms or a specific diagnosis. Ask why the proposed strength and duration are needed and what the longer-term plan is. Repeated supply should not replace review of continuing symptoms.
