1 What Imodium capsules are and what they are
used for
The name of your medicine is Imodium capsules.

What Imodium capsules are used for
Imodium capsules are used:
• To treat sudden short-lived (acute) attacks
of diarrhoea in adults and children aged
9 years and above
• To treat long-lasting (chronic) diarrhoea
in adults
If your child is aged 9 years and above the
‘you’ stated everywhere below should be read
as ‘your child’.

How Imodium capsules work

Imodium capsules contain a medicine
called loperamide hydrochloride. It belongs
to a group of medicines which helps reduce
diarrhoea by slowing down an overactive
bowel. It also helps the body to absorb more
water and salts from the bowel.

2 Before you use Imodium capsules
Do not use Imodium capsules :

• If you are allergic to anything in Imodium
capsules (listed in section 6 below)
• If you have severe diarrhoea after taking
• If you are having a flare up of ulcerative colitis
• If you are constipated or your stomach
appears swollen
• For a child less than 9 years old
Imodium syrup can be used for children
over 4 years old

Do not use this medicine if any of the above
applies to you. If you are not sure, talk to your
doctor or pharmacist before using Imodium


2 Before you use Imodium capsules (continued)
Take special care with Imodium

Check with your doctor before using Imodium
capsules if:

of which may include blood in your stools

• You suffer from liver problems
• You have AIDS and your stomach becomes
swollen. Stop taking the capsules
immediately and contact your doctor
You may still be able to use Imodium capsules,
but you should discuss this with your doctor first.

Replacing fluid and salts

Imodium capsules only treat the symptoms
of diarrhoea. When you have diarrhoea,
your body loses large amounts of fluid
and salts. You should therefore replace
this lost fluid by drinking more than normal.
This is especially important for children.
Your doctor may also give you a special powder
containing sugar and salts (known as oral
rehydration therapy) to help your body replace
the fluid and salts lost during diarrhoea.

Taking other medicines

Please tell your doctor or pharmacist if you
are taking or have recently taken any other
medicines. This includes medicines that you
buy without a prescription or herbal medicines.
In particular, tell your doctor or pharmacist
if you are taking any of the following:
• ritonavir (used to treat HIV)
• quinidine (used to treat abnormal heart
rhythms or malaria)

fungal infections)
