I have used Hycodan, a cough suppressant, for several years.  It contains Hydrocodone, so you must take it with caution.  Lately, the Hycodan by itself was not always adequate (@ 5ml 4x per day) so my Pulmonologist recommended the Tessalon Perles generic benzonatate (@ 1 capsule 3x per day).  Latter helped me.  Good luck!
