1) What Serevent Evohaler is and what it is used for

Serevent Evohaler contains the medicine salmeterol. It is a ‘long-acting
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.

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 beta-blockers as they may reduce or
abolish the effects of salmeterol.

Serevent can reduce the amount of potassium in your blood. If this
happens you may notice an uneven heartbeat, muscle weakness or
cramp. This is more likely to happen if you take Serevent with some
medicines used to treat high blood pressure (diuretics) and other
medicines used to treat breathing problems such as theophylline or
steroids. Your doctor may ask for you to have blood tests to check the
amount of potassium in your blood. If you have any concerns discuss
them with your doctor.

Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are
planning to have a baby, ask your doctor or pharmacist for advice before
taking this medicine.
Driving and using machines
The possible side effects associated with Serevent Evohaler are unlikely to
affect your ability to drive or use machines.

3) How to use Serevent Evohaler
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 Evohaler every day, until your doctor advises you to stop.
 You will start to feel your medicine working within the first day of use.
Serevent is for inhalation by mouth only.
Adults and adolescents aged 12 years and older with Asthma
 The usual starting dose is 2 puffs twice a day.
 For people with more severe asthma, your doctor may increase your
dose to 4 puffs twice a day.

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

Children with Asthma
 In children aged 4 to 12 the usual dose is 2 puffs twice a day.
 Serevent is not recommended for use in children below 4 years of age.

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

Adults with Chronic Obstructive Pulmonary Disease
including bronchitis and emphysema
 The usual starting dose is 2 puffs twice a day.
 Not applicable for children and adolescents.

If you are being treated for asthma, you should always be given both
a Serevent Evohaler 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 Evohaler. 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.


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

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.

Once your asthma is well controlled your doctor may consider it
appropriate to gradually reduce the dose of Serevent Evohaler

If you have been prescribed Serevent Evohaler 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

Using your inhaler
It is important to start to breathe in as slowly as possible just before using
your inhaler.

overactive thyroid gland, diabetes mellitus (Serevent may increase
your blood sugar) or heart disease, including an irregular or fast

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 heartbeats, or may make
side effects worse.
