hi,
you have not mentioned from how long you this symptom, i cannot tell if have and infection or
allergy, but assuming your doctor gave you
butalin , which is given in
asthma , you may be having allergy which increases at night. for allergy the treatment should be in step wise manner.
first if your symptoms is for few months a year like 2-3 months then you start an antihistamine which you have to take daily at night. if your symptoms still persist then your start using
steroid nasal spray, it has no side effect and it controls the allergy very well and you should start 2 weeks before your symptoms start. if this also does not cure you.
then get yourself tested for allergy, it is called skin prick test you will know what you are allergic to, then if possible you can avoid the allergen or you can start treatment called immunotherpy. this is currently the best treatment available and your symptoms will easily reduce by 80-90 percent kindly visit your
ent specialist he will guide you further.
for asthma its better you go to pulmonologist , and he will find out if you really have asthma,
in case you do have then you will have to take asthma inhalers,depending on your frequency of symptom.
and for the above medicine, you take for another 2-3 days and make sure your fully fine then you can stop it. thank you
