Asthma is a very common long-term condition that
is caused by inflammation of the airways. It
causes coughing, breathlessness and wheezing and
affects 5.4 million people in the UK. The
severity of asthma can vary enormously from
person to person and it can be life threatening,
but for many people, their asthma can be well
controlled much of the time by prescribed
medication.

prescription if appropriate.
The underlying cause of asthma is inflammation
of the airways. The small tubes that carry air
into and out of the lungs become sensitive to
“trigger” factors that cause the airways to
narrow and become full of sticky mucus or
phlegm. This makes breathing more difficult,
with wheezing and coughing and a feeling of
tightness in the chest.
An asthma attack happens when a trigger factor
causes a sudden onset of these symptoms. Such an
asthma attack can be very dangerous. Some people
have long-term asthma that means long-term
narrowing of the airways is present.
The trigger factors vary from person to person
and in many cases cannot be avoided as they are
a part of everyday life. Many people with asthma
have more than one trigger. Common trigger
factors are house dust mites, animal fur,
pollen, smoke, exercise, cold air
and infections.
The actual cause of the increase in sensitivity
of the airways is not totally understood. It is
known to run in families and so is at least in
part to do with your genetic makeup.

Asthma cannot be cured, so the main aims of
treatment are to prevent symptoms and future
asthma attacks, and to relieve the symptoms of
asthma should they occur. The medicines that are
used in asthma are usually divided into
“preventers” and “relievers”.
In most cases, the medicines are inhaled so they
take effect directly in the lungs. It is very
important that the inhaler is correctly used to
ensure the medicine does make it into the lungs.
Even experienced users of inhalers should review
their “inhaler technique” on a regular basis as
bad habits are easy to pick up and important
steps easy to forget. Good
inhaler technique is well summarised by
Asthma
UK on their website.
Preventer medicines are taken on a regular
basis, usually every day. They should be taken
even if your asthma is well controlled as they
are there to ensure that you avoid symptoms as
much as possible and avoid asthma attacks in the
future. The effect of these medicines builds up
over time so it’s important to keep taking them
even when you feel well. Preventer medicines do
not give immediate help if you are having an
asthma attack. Common examples of preventer
medicines are:
Clenil
- Flixotide -
Pulmicort -
QVAR -
Seretide -
Serevent -
Symbicort
Reliever medicines are taken to quickly relieve
the symptoms of asthma or in an asthma attack.
Everyone who has asthma should always have their
reliever inhaler with them. If you are using
your reliever inhaler more than three times a
week, your asthma is not as well controlled as
it should be and so you should visit your doctor
or asthma nurse for a review to see how this can
be improved. Some common reliever medicines are:
Airomir -
Bricanyl -
Ventolin

GPs will review your case and can prescribe a

In order to prescribe you asthma treatment, we
will require your GP details. We will inform
your GP that we have prescribed you asthma
treatment (and which treatment we have
provided), and any subsequent times when it is
prescribed to you. This is to allow your own
doctor to safely monitor your asthma and your
treatment. Our service does not replace your own
GP asthma review. Unfortunately, we cannot
prescribe asthma treatment without consent to
contact your GP.
