6. Contents of the pack and other information
• 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 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.
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
• 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. Betablockers, 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 – 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.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, If you are
pregnant, planning to get pregnant or breast-feeding, talk to your doctor before taking Serevent. Your doctor will
assess whether you can take Serevent during this time.
Driving and using machines
The possible side effects associated with Serevent are unlikely to affect your ability to drive or use machines.
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 use.
Serevent is for inhalation by mouth only.

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 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.
