Imodium Instant Melts (Loperamide)

Imodium Instant Melts


1 What the medicine is for

Imodium Instant Melts is a medicine which is used to treat sudden short-lived (acute) attacks of diarrhoea in adults and children aged 12 years and over. It can also be used to treat diarrhoea associated with Irritable Bowel Syndrome (IBS) in adults aged 18 years and over after your doctor has diagnosed you are suffering from this condition.

The tablets contain loperamide hydrochloride which helps reduce diarrhoea by slowing down an overactive bowel, which helps the body to absorb water and salts from the bowel.
