Can the drug Inderal cause a nonproductive cough? I have been coughing for the past 10 days, but don't feel bad at all. I am taking 80 mg for familiar tremors. I am a 55 year old male, 6 ft. 220 lbs., with no history of heart disease. I take wellbutrin 450 mg., vytorin 10/40 mg, singular 10 mg, zertec 10 mg, and prilosec.
