I am a 68 year old female and weigh 168lbs. I have had a stomach flu for 4 days and have been taking 8mgs of generic Zofran. I also take 60mg of generic Cymbalta. I am not getting better and I think that there is a serious interaction between these 2 drugs as I am not getting better. I constantly have reflux and really can'i lay back to rest or sleep. I take 88mg Synthroid (thyroid removed) and 10mg lisinipril, a 40mg PPI, 60mg of Cymbalta and a cholesterol med. Please tell me if this Zofran/Cymbalta interaction should be discontinued.
