Boy, this has me really PO'd.
I was on amitriptyline 150mg WITH zoloft back in the 90's when that was what they used for pain.....or 'fibro' and its concomittant 'depression'. And those dipsh#ts never took a blood level of the amitrip. I would ask, and they would say....'you don't need it'. This was the same HMO linked clinic that I was with for 11 years and left, only to be diagnosed with neuropathy and SjS.
I could never prove a case and at this stage, it would not be worth the stress, since litigation is horrible on one's health.
It makes me wonder about the whole thing on drugs...consume at your own risk, I guess.
