Q – This has been going on for close on 5 months. I would say to hell with this softly softly approach – nip it in the bud so you can get on with your life.
Inhaled steroids are a preventative maintenance treatment for asthma. During asthma "flare-ups" even doubling the dose etc may not prove effective in getting things back on an even keel, and even when they work in such circumstances it will take a number of weeks to really have an effect.
Oral steroids are nasty drugs, if you are on them for any length of time (months), but a short course ( a few days) will have no long lasting side effects.
A typical short course of Pred (say 40mg per day ) is perhaps 100x more than 4 puffs of a steroid inhaler. Plus, it has the benefit of getting into the blood stream and to the lungs. Perhaps only 50% of an inhaled steroid reaches the lungs using a standard MDI.
Whenever I have taken Oral Steroids and it has not been very often (3 times in the last 5 years) then there has been significant improvement within the first 24 hours.
