1. What Serevent Evohaler is and what it is used for
 Serevent Evohaler contains the medicine salmeterol. It is a ‘longacting bronchodilator’. It helps the airways in the lungs to stay
open. This makes it easier for air to get in and out. The effects are
usually felt within 10 to 20 minutes and last for 12 hours or more.
 The doctor has prescribed it to help prevent breathing problems.
These could be caused by asthma. Taking Serevent Evohaler
regularly will help prevent asthma attacks. This also includes
asthma brought on by exercise or at night.
 Taking Serevent Evohaler regularly will also help prevent
breathing problems caused by other chest illnesses such as
Chronic Obstructive Pulmonary Disease (COPD).
 Serevent Evohaler helps to stop breathlessness and wheezing
coming on. It does not work once you are breathless or wheezy.
If that happens, you need to use a fast-acting ‘reliever’ medicine,
such as salbutamol.
 Serevent Evohaler is supplied to you in an inhaler. You breathe
the medicine directly into your lungs.
 Serevent Evohaler contains norflurane. This is less harmful to the
environment than older inhalers. Older inhalers may taste
differently to Serevent Evohaler. This will make no difference to
how your medicine works.
If you are being treated for asthma, you should always be given
both a Serevent and a steroid inhaler to use together.
2. What you need to know before you use Serevent Evohaler
Do not take Serevent Evohaler if:
you are allergic (hypersensitive) to salmeterol or to the other
ingredient norflurane (HFA 134a).
Take special care with Serevent Evohaler
 If your asthma or breathing gets worse tell your doctor
straight away. You may find that you feel more wheezy, your
chest feels tight more often or you may need to use more of your
fast-acting ‘reliever’ medicine. If any of these happen, do not
increase your number of puffs of Serevent. Your chest condition
may be getting worse and you could become seriously ill. See
your doctor as you may need a change in asthma treatment.
 Once your asthma is well controlled your doctor may consider it
appropriate to gradually reduce the dose of Serevent.
 If you have been prescribed Serevent for your asthma, continue to
use any other asthma medication you are already taking. These
could include a steroid inhaler or steroid tablets. Continue taking
the same doses as before, unless your doctor tells you otherwise.
Do this even if you feel much better. Do not stop taking your
steroid inhaler (or any steroid tablets) when you start using

Always use this medicine exactly as your doctor or pharmacist has
told you. Check with your doctor or pharmacist if you are not sure.
 If you are being treated for asthma, you should always be
given both a Serevent and a steroid inhaler to use together.
 Use Serevent every day, until your doctor advises you to stop.
 You will start to feel your medicine working within the first day of
Serevent is for inhalation by mouth only.
Adults and adolescents aged 12 years and older with Asthma

 For people with more severe asthma, your doctor may increase
your dose to 4 puffs twice a day.

Instructions for use
Your doctor, nurse or pharmacist should show you how to use your
inhaler. They should check how you use it from time to time. Not using
the inhaler properly or as prescribed, may mean that the medicine will
not help your asthma or COPD as it should.
The medicine is contained in a pressurised canister in a plastic casing
with a mouthpiece.
Testing your inhaler
1. When using your inhaler for the first
time, test that it is working. Remove the
mouthpiece cover by gently squeezing
the sides with your thumb and forefinger
and pull apart.
2. To make sure that it works, shake it
well, point the mouthpiece away from you
and press the canister to release two
puffs into the air. If you have not used the
inhaler for a week or more, also release
two puffs of medicine into the air.
Using your inhaler
It is important to start to breathe in as slowly as possible just before
using your inhaler.
1. Stand or sit upright when using your inhaler.
2. Remove the mouthpiece cover (as shown in the first picture).
Check inside and outside to make sure that the mouthpiece is
clean and free of objects.

3. Shake the inhaler 4 or 5 times to ensure that any
loose objects are removed and that the contents of
the inhaler are evenly mixed.

 Your doctor may want to check your health regularly if you have
an overactive thyroid gland, diabetes mellitus (Serevent may
increase your blood sugar) or heart disease, including an irregular
or fast heartbeat.
Other medicines and Serevent
 Tell your doctor if you are taking or have recently taken any other
medicines. This includes those for asthma or any other medicines
obtained without a prescription. This is because Serevent may not
be suitable to be taken with other medicines.
 Inform your doctor before using Serevent if you are currently being
treated for any fungal infections with medicines containing
ketoconazole or itraconazole, or if you are being treated for HIV
with ritonavir. These medicines may increase the risk of you
experiencing side effects with Serevent, including irregular heart
beats, or may make side-effects worse.
 Beta-blockers should be avoided when taking Serevent, unless
your doctor tells you to take them. Beta-blockers, including
atenolol, propranolol and sotalol, are mostly used for high blood
pressure or other heart conditions. Tell your doctor if you are
taking beta-blockers or have recently been prescribed betablockers as they may reduce or abolish the effects of salmeterol.

4. Hold the inhaler upright with your thumb on the
base, below the mouthpiece. Breathe out as far as is

5. Place the mouthpiece in your mouth between
your teeth. Close your lips around it. Do not bite.

6. Breathe in through your mouth. Just after
starting to breathe in, press down on the top of
the canister to release a puff of medicine. Do
this while still breathing in steadily and deeply.

7. Hold your breath, take the inhaler from your
mouth and your finger from the top of the inhaler.
Continue holding your breath for a few seconds,
or as long as is comfortable.


Wait about half a minute between taking each puff of medicine
and then repeat steps 3 to 7.
After use always replace the mouthpiece cover immediately to
keep out dust. Replace the cover by firmly pushing and
snapping the cap into position.

Practice in front of a mirror for the first few times. If you see a ‘mist’
coming from the top of your inhaler or the sides of your mouth you
should start again
If you or your child find it difficult to use Serevent Evohaler, it may be
used with other devices to make its use easier e.g. a Haleraid® or
Volumatic® spacer device. Serevent is also available in an alternative
device. Talk to your doctor, nurse or pharmacist for further advice.
