4 Possible side effects
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).

Package Leaflet: Information for the User
50 microgram per dose inhalation powder
salmeterol xinafoate

1 What Serevent Diskhaler is and what it is used for
• Serevent Diskhaler consists of Rotadisks ® and an inhaler called a Diskhaler. Rotadisks have foil blisters
containing the medicine salmeterol. Refill packs are also available which contain only the Rotadisks and
not the Diskhaler.
• Serevent 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 Diskhaler regularly will help prevent asthma attacks. This also includes asthma brought
on by exercise or at night.
• Taking Serevent Diskhaler regularly will also help prevent breathing problems caused by other chest
illnesses such as Chronic Obstructive Pulmonary Disease (COPD).
• Serevent Diskhaler 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 a Diskhaler. 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 Before you use Serevent Diskhaler
Do not take Serevent Diskhaler if:
you are allergic (hypersensitive) to salmeterol xinafoate, or to the other ingredient lactose monohydrate.

Take special care with Serevent Diskhaler
• 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 blisters 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.

Taking other medicines
• Please 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.
• Please 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 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 presssure (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, 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.

3 How to use Serevent Diskhaler
• 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. Serevent is for inhalation by mouth only.
