WHAT SEREVENT EVOHALER IS AND WHAT IT IS USED FOR
Serevent Evohaler 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 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 salbutamol.
Serevent Evohaler is supplied to you in an inhaler. You breathe the medicine directly into
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 works.
The usual starting dose is 2 puffs 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 inhaler properly or as prescribed, may mean
that the medicine will not help your asthma or COPD as it should.
The medicine is contained in a pressurised canister in a plastic casing with a mouthpiece.
Testing your inhaler
When using your inhaler for the first time, test that it is
Remove the mouthpiece cover by gently squeezing
the sides with your thumb and forefinger and
To make sure that it works, shake it well, point the
mouthpiece away from you and press the canister to
release two puffs into the air. If you have not used
the inhaler for a week or more, also release two puffs
of medicine into the air.
If you are being treated for asthma, you should always be given both a Serevent
Evohaler and a steroid inhaler to use together.
HOW TO USE SEREVENT EVOHALER
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
Evohaler and a steroid inhaler to use together.
• Use Serevent Evohaler every day, until your doctor advises you to stop.
• You will start to feel your medicine working within the first day of use.
Serevent Evohaler is for inhalation by mouth only.
WHAT YOU NEED TO KNOW BEFORE YOU USE SEREVENT EVOHALER
Do not take Serevent Evohaler if:
Using your inhaler
Take special care with Serevent Evohaler
Stand or sit upright when using your inhaler.
Remove the mouthpiece cover (as shown in the first picture). Check inside and outside to
make sure that the mouthpiece is clean and free of objects.
Shake the inhaler 4 or 5 times to ensure that any loose
objects are removed and that the contents of the inhaler
are evenly mixed.
Hold the inhaler upright with your thumb on the base,
below the mouthpiece. Breathe out as far as is comfortable.
Place the mouthpiece in your mouth between your teeth.
Close your lips around it. Do not bite.
It is important to start to breathe in as slowly as possible just before using your inhaler.
You are allergic (hypersensitive) to salmeterol or to the other ingredient norflurane (HFA 134a).
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 Evohaler. 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 Evohaler.
If you have been prescribed Serevent Evohaler 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 Evohaler.
Your doctor may want to check your health regularly if you have an overactive thyroid
gland, diabetes mellitus (Serevent Evohaler may increase your blood sugar) or heart
disease, including an irregular or fast heartbeat.
Other medicines and Serevent Evohaler
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 Evohaler may not be suitable to be taken with other medicines.
Inform your doctor before using Serevent Evohaler 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 Evohaler, including irregular heartbeats, or may make side effects
Beta-blockers should be avoided when taking Serevent Evohaler, 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 betablockers or have recently been prescribed beta-blockers as they may reduce or abolish the
effects of salmeterol.
Serevent Evohaler 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 Evohaler 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.
