Thanks for your question on Health Care Magic.
I can understand your wife's situation and problem.
Wheezing since 8 years is commonly seen with asthma or
bronchitis.
So better to
consult pulmonologist and get done PFT (Pulmonary Function Test) for the diagnosis of asthma and bronchitis.
PFT will also tell you about severity of the disease and treatment is based on severity only.
She is taking only
budecort . It contains
budesonide. It is inhaled corticosteroid (ICS). Along with ICS, inhaled bronchodilators are also useful for control of wheezing.
Oral antihistamine and anti allergic drugs are also beneficial.
So better to consult pulmonologist, get done PFT and discuss all these.
Don't worry, she will be alright.
Hope I have solved your query.
I will be happy to help you further. Wishing good health to your wife. Thanks.
