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.


Your medicine is known by the above name but will be referred to as
Serevent Accuhaler throughout this:
Patient Information Leaflet
Read all of this leaflet carefully before you start taking this medicine
because it contains important information for you.
 Keep this leaflet. You may need to read it again.
 If you have any further questions, ask your doctor or pharmacist.
 This medicine has been prescribed for you only. Do not pass it on to others.
It may harm them, even if their signs of illness are the same as yours.
 If you get any side effects, talk to your doctor or pharmacist. This includes
any possible side effects not listed in this leaflet. See section 4.
In this leaflet:
1) What Serevent Accuhaler is and what it is used for
2) What you need to know before you use Serevent Accuhaler
3) How to use Serevent Accuhaler
4) Possible side effects
5) How to store Serevent Accuhaler
6) Contents of the pack and other information

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. Please tell your doctor if you are taking betablockers 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-water tablets)
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.

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

Serevent Accuhaler 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 Accuhaler
regularly will help prevent asthma attacks. This also includes asthma
brought on by exercise or at night.
Taking Serevent Accuhaler regularly will also help prevent breathing
problems caused by other chest illnesses such as Chronic Obstructive
Pulmonary Disease (COPD).
Serevent Accuhaler 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
Serevent is supplied to you in an inhaler called the Accuhaler. You
breathe the medicine directly into your lungs.

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 Accuhaler
Do not take Serevent Accuhaler if:
you are allergic (hypersensitive) to salmeterol xinafoate, or to the other
ingredient lactose.
Take special care with Serevent Accuhaler
 If you are using Serevent for asthma your doctor will want to
regularly check your symptoms.

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

Using your inhaler
1 To open your Serevent Accuhaler, hold the
outer case in one hand and put the thumb of
your other hand on the thumbgrip. Push your
thumb away from you as far as it will go. You

the mouthpiece.
2 Hold your Serevent Accuhaler with the
mouthpiece towards you. You can hold it in
either your right or left hand. Slide the lever
away from you as far as it will go. You will hear
a click. This places a dose of your medicine in
the mouthpiece.

Every time the lever is pushed back a blister is opened inside and the
powder made ready for you to inhale. Do not play with the lever as this
opens the blisters and wastes medicine.

as is comfortable. Do not breathe into your Serevent Accuhaler.

worse after using Serevent. You may be very wheezy and
cough. You may also notice itching and swelling (usually of the face, lips,
