1. What Intal is and what it is
used for
Intal CFC-free Inhaler (called Intal in this
leaflet) contains a medicine called sodium
cromoglicate. This belongs to a group of
medicines called anti-allergics.
It works by having an effect deep in the air
passages of your lungs. It also lowers your
response when you are exposed to substances
to which you are allergic.
Intal is used to help prevent asthma attacks
and may be called a ‘preventer’:
● Intal will not help an asthma attack that
has already started
● You will need to use a different inhaler,
called a ‘reliever’, for these attacks (see
Using a ‘reliever’ inhaler in Section 3)
2.Before you use Intal
Do not use this medicine and tell
your doctor if:
✖ You are allergic (hypersensitive) to sodium

cromoglicate or any of the other
ingredients of Intal (listed in Section 6:
Further information).
Signs of an allergic reaction include: a rash,
swallowing or breathing problems, swelling of
your lips, face, throat or tongue
Do not use this medicine if the above applies
to you. If you are not sure, talk to your
doctor or pharmacist before using Intal.

Take special care with Intal
Check with your doctor or
pharmacist before using your
medicine if:
▲ You have recently stopped taking ‘steroids’
and your asthma is getting worse (see
Taking other medicines below)
▲ You are suffering from stress, trauma,
infections or other illnesses
If you are not sure if any of the above apply
to you, talk to your doctor or pharmacist
before using Intal.
Taking other medicines
Please tell your doctor or pharmacist if
you are taking or have recently taken
any other medicines. This includes medicines
you buy without a prescription, including
herbal medicines. This is because Intal can
affect the way some other medicines work. Also
some medicines can affect the way Intal works.
In particular, tell your doctor if you are also
using a steroid medicine:
● This can be either an inhaler (such as
beclometasone) or a tablet (such as
● If you are using a steroid as well as Intal,
your doctor may decide to lower the
amount of steroid taken or gradually stop
the steroid altogether
If your steroid treatment has been reduced or
stopped and your asthma then gets worse you
must tell your doctor straight away. They may
wish to increase or re-start the steroid
Pregnancy and breast-feeding
Talk to your doctor before using this medicine
if you are pregnant, might become pregnant
or think you may be pregnant.
If you are breast-feeding or planning to
breast-feed, talk to your doctor or pharmacist
before using this medicine.

3. How to use Intal
Always use Intal exactly as your doctor has
told you. You should check with your doctor
or pharmacist if you are not sure.
Using this medicine
● It is important to use this medicine every
day, even if you have no signs of asthma
● This medicine is taken by breathing in
through your mouth (see ‘How to use your
inhaler’ below)
● You may need to use Intal for several
weeks for it to work best
● Your asthma may get worse if you have an
infection, are unwell or come into contact
with anything to which you are allergic. If
this happens, talk to a doctor straight away
● If you feel the effect of your medicine is
too weak or too strong, do not change the
dose yourself, but ask your doctor,
especially if you think it is too weak
How much to use (adults, elderly and
● The starting dose is two puffs (inhalations)
four times each day
● Taking puffs at meal times and at bedtime
may help you to remember to use it
● When your asthma gets better, your doctor
may suggest that you lower your daily dose
to one puff four times each day
● Your doctor may also suggest you take an
additional dose before exercise
● Sometimes when your asthma is bad or
when you come into contact with anything
to which you are allergic, your doctor may
change how much you use. Your dose may
be increased to two puffs six to eight times
each day

Using a ‘reliever’ inhaler
● If your doctor has advised you to use a
‘reliever’ inhaler at the same time as Intal,
it is best to use your ‘reliever’ inhaler
before using your Intal Inhaler. This will
open the airways and allow the Intal to get
down into them better
● Keep your ‘reliever’ inhaler at all times in
case of a sudden attack or if your asthma
gets worse. Talk to your doctor if it takes
more puffs than usual from your ‘reliever’
inhaler to control your symptoms
