Hello, thanks for the query to H.C.M.
are ingredients of dulera.
From 18 months you are using this medicine once earlier, now twice in day to get relief from wheezing ,coughing ,sneezing
, post nasal discharge
As far as concerned about smell rotten or burning or foul, that is a point disturbing to you.
Steroids ( mometasone ) is a drug which lower the blood cells that helps body to fight infections which lower immunity. This is one reason of smell.
Side effects are many but one of them is stuffy nose, sinus pain, sore throat
. Collectively one more reason of bad smell.
Once again consult the doctor and tell in detail about side effects of drugs and have another round of medicines.
Regards. Dr. HET
