1. What Loperamide is and what it is used for

Loperamide 2 mg hard capsules is used to treat two types of diarrhoea. The two types have different age limits.

Short-term diarrhoea
  • For adults and children aged 12 and over.
  • To treat attacks that last up to 48 hours.
  • If your attack lasts longer than 48 hours, talk to your doctor.

IBS diarrhoea
  • For adults and young people aged 18 and over who have been diagnosed with IBS (Irritable Bowel Syndrome).
  • To treat attacks that last up to 48 hours.
  • You can use this medicine for up to 2 weeks for repeated attacks, but if any one attack lasts continuously for longer than 48 hours, talk to your doctor.

This medicine contains loperamide hydrochloride, a substance that helps reduce diarrhoea by slowing down an overactive bowel. This allows water and salts that are usually lost in diarrhoea to be absorbed by the body.

2. What you need to know before you take Loperamide
