Steroids are the most effective way of controlling inflammation in your lungs. The steroids used in asthma are 'corticosteroids'. They have been widely and safely used to treat asthma for many years. Corticosteroids are naturally made in our bodies by the adrenal gland. When you use a steroid inhaler, or steroid tablets, you add to this natural corticosteroid.
Corticosteroid treatment is used in asthma, eczema and some forms of arthritis.
Corticosteroids are not the anabolic steroids used by some body builders and athletes. You will not put on weight or become muscular from using inhaled steroids. Tablet steroids may increase your appetite and indirectly lead you to put on weight. Need to be taken every day, even if you are feeling well, to build up their protective effect. Don't give immediate or quick relief when you are breathless, but reduce long-term inflammation.
