Xanthine derivatives, steroids, diuretics and laxatives can all cause the level of
potassium in your blood to fall. Your doctor will wish to monitor this and therefore from
time to time may need to carry out a blood test to check your potassium levels.
Pregnancy, breast-feeding and fertility
The safe use of salbutamol during pregnancy has not been established. Tell your doctor
if you are pregnant, if you think that you may be pregnant or if you are trying to become

3. HOW TO USE ASMAVENT® CFC-FREE INHALER
Asmavent® CFC-free Inhaler is a pressurised inhalation suspension (inhaler) which
contains the active ingredient salbutamol (as salbutamol sulphate). Salbutamol belongs
to a group of medicines called short-acting ß2 agonists, bronchodilators or “relievers”.
Salbutamol is used by patients with asthma as it helps to relieve the symptoms of asthma
such as wheezing, shortness of breath, tightness in the chest and cough. Salbutamol is
also used to prevent symptoms of asthma which are brought on by exercise or allergens
such as house dust mite, pollen, cigarette smoke, cat and dog fur, etc.
Salbutamol can also be used to relieve symptoms such as chest tightness, wheezing,
shortness of breath and coughing in some other chest diseases.
Salbutamol acts directly on the muscles in the walls of the airways in the lung causing the
muscles to relax. This widens or opens up your airways making it easier to breathe.
Asmavent® CFC-free Inhaler cannot be used with any spacing device at this time.
If you need a spacing device, your doctor will need to prescribe another product,
which can be used with a spacing device, instead of Asmavent ® CFC-free

1. WHAT ASMAVENT® CFC-FREE INHALER IS AND WHAT IT IS USED
How to use your inhaler:
1.If your inhaler is new, or if you have not used your inhaler for a week or m ore, shake
well, remove the mouthpiece cover and release two sprays into the air before using.
2.Remove the mouthpiece cover and check that the inside and outside of the
mouthpiece is clear of dust, dirt or foreign objects (figure 1).
3.If the inhaler is very cold, the canister should be t aken out of the plastic actuator and
warmed in your hands for a few minutes before you use it. Do not use anything else to
warm the canister. Shake the inhaler before each use (figure 2).
4.Hold the inhaler upright with a thumb on the base. Breathe out as far as is comfortable
(it is important that you practice this before using the inhaler – see “Breathing
technique” (figure 3).
5.and then immediately place the mouthpiece in your mouth and close your lips around
it (figure 4). Be careful not to bite the mouthpiece.
6.Breathe i n s lowly t hrough y our m outh. J ust af ter s tarting t o br eathe i n t hrough y our
mouth, press firmly down on the top of the inhaler to release an actuation (puff). Carry
on breathing in deeply and steadily (figure 4).
7.Hold your breath, take the inhaler from your mouth and take your finger away from the
top of the inhaler. Continue holding your breath for about 10 seconds, or for as long as
is comfortable (figure 5). Then breathe out slowly.
8.If you are taking another puff, keep the inhaler upright and wait for at least 30 seconds
before repeating steps 3 – 7.
9.After use, replace the mouthpiece cover firmly, making sure it snaps into position.
You must breathe in as slowly as possible just before using the inhaler. Do not rush steps
5 to 7. You should practice a few times in front of a mirror. If you see “mist” coming from
the inhaler or the sides of your mouth, then you need to start again from step 3.
People with weak hands may find it easier to hold the inhaler with two hands, with the two
forefingers on the top of the inhaler and both thumbs on the bottom under the
Cleaning your inhaler
You should follow the cleaning instructions described below very carefully in
order to ensure that your inhaler continues to work properly.
Clean your inhaler once a week, or if blocked.
1. First remove the metal can from the plastic actuator and take off the mouthpiece
2. Rinse the plastic actuator, mouthpiece and mouthpiece cover in tap water. DO NOT
place the metal can into water or clean the can using water. Make sure the water runs
through the actuator from both ends to ensure that the actuator orifice (the small hole
that can be seen through the mouthpiece) is clear and not blocked.
3. The plastic components (actuator and mouthpiece cover) should be placed in a warm
place to dry thoroughly before putting the inhaler back together. Avoid drying near
direct or excessive heat.
If you use more of your Asmavent® CFC-free Inhaler than you should
If y ou accidentally use too many puffs, you may feel shaky, have a fast heartbeat,
headache, feel tense or experience flushing. These effects usually wear off within a few
hours but if they do not wear off or are troublesome you must tell your doctor as soon as
possible or go to your nearest hospital casualty department.
Low levels of potassium in the blood may also occur if you take too much salbutamol and
therefore your doctor may want to do some blood tests to monitor your potassium levels.
Do not use more than 2 puffs in 4 hours and never use more than 8 puffs in 24
hours. If you have any further questions on the use of this product, ask your doctor,
asthma nurse or pharmacist.
4. POSSIBLE SIDE EFFECTS
Like all m edicines, A smavent® CFC-free I nhaler can c ause side effects, a lthough no t
everybody gets them.
Side effects may include:
Common (seen in less than 1 in 10 people and more than 1 in 100 people):
• tremor (shakes – especially noticeable in your hands)
• rapid heartbeat (with or without flushing)
Uncommon (seen in less than 1 in 100 people and more than 1 in 1000 people):
• palpitations (faster or stronger heartbeats) or changes in your heartbeat (uneven or
• changes in the rate or rhythm of the heartbeat
• mouth and throat irritation
• muscle cramps
Rare (seen in less than 1 in 1000 people and more than 1 in 10,000 people):
• low potassium levels in blood. Since salbutamol can change the salt balance in your
body, your doctor may occasionally need to take a blood sample to check the
Very rare (occurring in less than 1 in 10,000 people):
• Allergic reactions, which might include any of the following:
rapid swelling of the mouth, lips, tongue, face, ears, neck or throat (angioedema)
itching, raised bumps and/or redness on the skin (urticaria)
constriction of the small air passages in the lungs (bronchospasm)
low blood pressure (hypotension)
• Cardiac Arrythmias
• Restlessness or excitability (hyperactivity – particularly in children)
Unknown: Myocardial Ischaemia
There is some evidence from post-marketing data and published literature of rare
occurrences of myocardial ischaemia associated with salbutamol.
If your breathing or wheezing gets worse immediately after using your inhaler,
then stop using it immediately and contact your doctor straightaway. You may
need to use a different “reliever” inhaler to treat your symptoms.
Patients with underlying severe heart disease (e.g. ischaemic heart disease, arrhythmia
or s evere h eart f ailure) who ar e r eceiving s albutamol contact y our doctor if t hey
experience chest pain or other symptoms of worsening heart disease.
If the relief of your symptoms is not as good as usual, or it does not last as long as usual,
tell your doctor as soon as possible. This might mean that your asthma is getting worse
and your treatment needs to be changed.
If any of the side effects get worse or become severe, or if you have any side effects not
listed in this Leaflet, or if you are concerned in any way, please tell your doctor, asthma
nurse or pharmacist.
