Inhaled corticosteroids: What They Do, Medicines
Inhaled corticosteroids are preventer medicines that reduce swelling and irritation inside the airways. They are used regularly, not only during a bout of symptoms, to lower the chance of asthma symptoms. They do not give quick relief during an attack, so a separate reliever inhaler is usually also needed. They should not be stopped suddenly without speaking to a doctor.

Common questions
Why do I need to use a steroid inhaler even when I feel well?
It works by preventing symptoms, so the benefit builds up with regular use and fades if doses are missed. Feeling well often means the inhaler is working. Do not stop or change it on your own; ask your doctor, nurse or pharmacist first.
Can an inhaled steroid cause thrush or a hoarse voice?
It can, because some medicine stays in the mouth and throat. Rinsing your mouth with water or brushing your teeth after each use may help, as may using a spacer if one was prescribed. Tell your doctor if you notice white patches or soreness in the mouth.
Are steroid inhalers the same as steroid tablets?
They are related medicines, but an inhaler delivers a small amount mainly to the lungs, so effects on the rest of the body are much less likely than with tablets. Higher doses over long periods need monitoring. Ask your doctor if you have concerns.
