Foundayo Diarrhoea: How Long Does It Last and What Can Help?

Can Foundayo cause diarrhoea?

Yes.

Diarrhoea is classed as a very common adverse reaction to Foundayo.

When does Foundayo diarrhoea occur?

Diarrhoea may be particularly noticeable while increasing doses.

Clinical trial data showed that nausea, vomiting and diarrhoea occurred more frequently during dose escalation and tended to reduce as treatment continued.

What can help?

Maintaining hydration is particularly important.

Drink regularly throughout the day and consider appropriate oral rehydration if you are losing substantial amounts of fluid.

Some patients also find that large or very rich meals worsen gastrointestinal symptoms.

How long does Foundayo diarrhoea last?

There isn't a single timeframe that applies to everyone.

Mild diarrhoea may settle as your body adjusts, but persistent symptoms deserve assessment.

When should I speak to a healthcare professional?

Seek advice if you experience:

• persistent diarrhoea
• inability to maintain fluid intake
• dizziness or faintness
• significantly reduced urine
• blood in the stool
• fever
• severe abdominal pain.

Vomiting and diarrhoea can lead to dehydration and, in some circumstances, impaired kidney function.
