PATIENT INFORMATION LEAFLET
Your medicine is available using either of the above names, but will be referred to as Serevent
Accuhaler throughout this leaflet.
Beta-blockers should be avoided when taking Serevent Accuhaler, 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 Accuhaler 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 Accuhaler 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.

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.

or use machines.
This medicine contains lactose. If you have been told by your doctor that you have an intolerance to
some sugars, contact your doctor before taking this product.

WHAT SEREVENT ACCUHALER IS AND WHAT IT IS USED FOR
Serevent Accuhaler 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 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 salbutamol.
Serevent Accuhaler 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 Accuhaler
and a steroid inhaler to use together.
HOW TO USE SEREVENT ACCUHALER
Always use this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or
pharmacist if you are not sure.
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.
The usual starting dose is 1 puff twice a day.
Not applicable for children and adolescents.
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 Serevent Accuhaler properly or as prescribed may
mean that it will not help your asthma or COPD as it should.
The Serevent Accuhaler device holds blisters containing Serevent Accuhaler as a powder.
There is a counter on top of the Serevent Accuhaler which tells you how many doses are left.
It counts down to 0. The numbers 5 to 0 will appear in red to warn you when there are only a few
doses left. Once the counter shows 0, your inhaler is empty.
Using your inhaler
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 will hear
a click. This will open a small hole in the mouthpiece.
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.
Hold the Serevent Accuhaler away from your mouth, breathe out as far as is comfortable.
Do not breathe into your Serevent Accuhaler.
Put the mouthpiece to your lips; breathe in steadily and deeply
through the Serevent Accuhaler, not through your nose. Remove
the Serevent Accuhaler from your mouth. Hold your breath for
about 10 seconds or for as long as is comfortable. Breathe out
WHAT YOU NEED TO KNOW BEFORE YOU USE SEREVENT
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 Accuhaler for asthma your doctor will want to regularly check
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 Accuhaler. 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 Accuhaler.
If you have been prescribed Serevent Accuhaler 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 Accuhaler.
Your doctor may want to check your health regularly if you have an overactive thyroid gland,
diabetes mellitus (Serevent Accuhaler may increase your blood sugar) or heart disease, including
an irregular or fast heartbeat.
Other medicines and Serevent Accuhaler
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
Accuhaler may not be suitable to be taken with other medicines.
Inform your doctor before using Serevent Accuhaler 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 Accuhaler, including irregular heart beats, or may make side-effects worse.

Afterwards rinse your mouth with water and spit it out. This may help to stop you getting thrush
and being hoarse.
To close the Serevent Accuhaler, slide the thumbgrip back towards
you, as far as it will go. You will hear a click. The lever will return
to its original position and is reset.
