6 Contents of the pack and other information
• 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
• 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.

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

are unlikely to affect your ability to drive or use
Always use this medicine exactly as your doctor or
pharmacist has told you. Check with your
doctor or pharmacist if you are not sure.

a steroid inhaler to use together.

Like all medicines, Serevent can cause side
effects, although not everybody gets them. To
reduce the chances of side effects, your doctor will
prescribe the lowest dose of Serevent to control
your asthma or COPD. These are the side effects
reported by people taking Serevent.
Allergic reactions: you may notice your
breathing suddenly gets worse after using
Serevent. You may be very wheezy and cough.
You may also notice itching and swelling (usually
of the face, lips, tongue or throat). If you get these
effects or they happen suddenly after using
Serevent, tell your doctor straight away. Allergic
reactions to Serevent are very rare (they affect
less than 1 person in 10,000).
Other side effects are listed below:

If you or your child find it difficult to use Serevent

doctor, nurse or pharmacist for further advice.
