Thank you. I had what seemed like a chest cold in March. it continued on and off and turned into a sore throat and cough in May. I m not sick at all.... just a constant cough and bringing up phlegm. Went to Pulmonologist who said it was set off by ashma - and a virus. Put me on Prednosone. Cough and phlegm got much better. Still didn t go away. Off Prednosone and cough and phlegm seem to be coming back. The only medication I am on is Losrtan - HCTZ 50 - 12.5 mg . I wonder if that is the cause of the cough and phlegm. I also have a post nasal drip and wonder if this is part of what is going on. Can the Losartan cause this?
