Thanks for query.
See the most important thing in treatment of asthma
is to acheive and maintain control of asthma. If your husband has no night symptoms, less than twice a week symptoms, normal physical activity, less than twice a week use of asthalin
inhaler and normal lung function then your husband has acheived asthma control. In that case the dose reduction of your current asthma medication has to be done if those controlled is maintained for atleast 3 months. So i advise you -
1. consult a pulmonologist
2. get locally examined
3. ask him whether control has acheived or not
4. go for a pulmonary function testing
5. let him do the necessary changes of your husband's current medication.
Usually it is better to have a lung function testing every 3 months or you can maintain a peak-flow chart by regular measurement of his peak flow by using a portable peak-flow meter. Because in asthma treatment self monitoring is very much important.
