Inhaled corticosteroids are usually delivered using a
inhaler (MDI) but are also often available for dry
powder inhalers (DPI).
Corticosteroids decrease inflammation in
the airways (reducing swelling and
mucus production), making breathing easier.
corticosteroids may be used to treat
chronic obstructive pulmonary disease (COPD) when
symptoms rapidly get worse (COPD exacerbation), especially when
there is increased mucus production.
Inhaled corticosteroids may be used to treat stable symptoms
of COPD or symptoms that are slowly getting worse. Inhaled corticosteroids may
decrease the number of COPD exacerbations in people with severe COPD,
particularly those with
chronic bronchitis and frequent exacerbations.
Corticosteroids may be useful for people who have
asthma as a component of their disease.
Research results on oral corticosteroids for COPD exacerbations show that:
Research on inhaled
Studies report that combining an inhaled corticosteroid
with a long-acting beta2-agonist resulted in:
Combining a corticosteroid with a beta2-agonist and an
But people who used fluticasone combined with a
beta2-agonist were more likely to get
It is not possible to predict who will improve
with corticosteroid therapy. Lung function tests (spirometry) can
be done before and after using the medicine, to learn if it has helped.
All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.
Here are some important things to think about:
The possibility of side effects
increases as the dose of the medicine increases. Side effects are less likely
to occur when you use the inhaled form of the medicine.
Common side effects of oral corticosteroids include:
Oral corticosteroids also may increase blood sugar level,
which may lead to a type of diabetes caused by the medicine (secondary diabetes). If you already have diabetes, it
may make the diabetes harder to control.
Common side effects
of long-term use of oral corticosteroids include:
Common side effects of inhaled steroids
The U.S. Food and Drug Administration (FDA) has
reported that salmeterol may make breathing more difficult. If your wheezing
gets worse after taking salmeterol, call your doctor right
Using a device called a
spacer with your metered-dose inhaler and rinsing your
mouth with water and spitting the water out after inhaling should reduce these

Reference is not available in all systems.)
Inhaled corticosteroids are
preferred to oral corticosteroids for long-term treatment of COPD, because they
cause fewer side effects. But low-dose inhaled steroids do not always work as
well as high-dose oral steroids.
Long-term treatment with oral
corticosteroids is not recommended.8 Although
long-term treatment with inhaled corticosteroids reduces the frequency of COPD
exacerbations in some people, the long-term risks and whether the benefit is
worth the risks of long-term treatment is not known.2
Most doctors recommend that everyone using an inhaler also use a
spacer. Use of a spacer is especially important when
using an inhaler containing a steroid medicine. But you should not use a spacer with a dry
powder inhaler (DPI).
Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
