I have just been placed on erythromycin, for gastroporesis, but take a number of medication, inc trazadone, dycyclamine, losartin, soma,clonadine,Valium, Pepcid, promethozine, trileptal, hydrocodine, remeron, ventolin inhaler,lansoprol, sucrafate,fenfibrate,prednisone plaqunil, hydromorphine, lipitorand lyrica....I have become anorexic, prior to beginning the erythromycin......to help move food through my stomach. However, I had a sig adverse reaction, my 1st day on it, due to trazadone, with a large and dangerous reaction last evening. Can anyone help me determine the interactions? I fear even taking BP, Heart melds or pain or muscle relaxers.Thank you........please help, the interaction list on Google is very long and seems to involve some of these other med I take...."
