Your doctor will tell you how often you need to use
your inhaler. The effect of this medicine may be noticeable after a few
days but will only reach its maximum after a few weeks. This medicine
must be used regularly to be effective, so go on taking it even if you
don't have any symptoms. That means it’s doing its job. If you stop
taking it your asthma and chronic obstructive pulmonary disorder (COPD)
may get worse. It should not be used to relieve sudden asthma attacks.
If an asthma attack occurs, use your quick-relief inhaler (reliever). To
get the benefit from this medicine you need to make sure you get your
inhaler technique right, otherwise, it does not work as well.
The
most common side effects are nausea, vomiting, respiratory tract
infection, fungal infections in the mouth, headache, hoarseness of
voice, sore throat, cough, musculoskeletal (bone, muscle, or joint)
pain, and increased heart rate. If you get there, do not stop taking it
but do talk to your doctor. You can help prevent some of these symptoms
by rinsing your mouth and throat with water or brushing your teeth after
using your inhaler. There are other, rarer side effects that can be
serious. Talk to your doctor if you're worried about them. In general,
you should be trying to avoid situations that make your asthma worse
(your triggers) and try not to smoke.
Ask your doctor whether
it’s safe to take this medicine if you're pregnant or breastfeeding.
Before taking it, you should tell your doctor if you have any kidney or
liver diseases so that your doctor can prescribe a suitable dose for
you.
