1. What Serevent Evohaler is and what it is used for
• Serevent Evohaler 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 Evohaler
regularly will help prevent asthma attacks. This also includes asthma
brought on by exercise or at night.
• 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
• 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
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 Evohaler
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
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 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) 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
The possible side effects associated with Serevent are unlikely to affect
your ability to drive or use machines.

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

less than 1 person in 10,000).
Other side effects are listed below:
Common (affects less than 1 person in 10):
• Muscle cramps
