Hi. I understand your concern s. If you have asthma you will need to undergo a detailed examination and investigation like pulmonary function test which is needed for the diagnosis as well as to assess severity of asthma based on which treatment can be started. Using need based levolin does not help. Please consult a pulmonologist to avoid any complications.

If the asthma has become that severe to the extent that you need to take nebulisation, I would recommend you to see a chest physcian. The dose/ frequency of nebulisation has to be monitored.

Yes it's safe beyond the doubt.
