I have found one way to help the enteric coated meds to work, and it's probably not the best thing, but it works. I use a file or scissor blade to scrape off some of the coating on each side to give the med a chance to break down in my system. I can tell that it works. I haven't done it for SR or ER or timed release meds, as there are too many variables, but for the run of the mill meds--i.e. benedryl, scraping off a bit of the coating gives them a chance of absorption.
I have told my back doctor's idiot PA no less than 12 times that I can't take SR meds, but she insists on writing the Rx for them anyway. Then I have to have her rewrite the Rx, which infuriates her, and you can just imagine the high quality of care I enjoy there. She's terribly rude and I have now insisted that she not have anything to do with my care, which pisses off the office. So far the back doc has been mildly okay with me just seeing him, but he STILL has her write the Rx, so the game continues. I have a feeling that when I am healed from the surgery they are going to fire me as a patient, as I am "too difficult." It's a very tense situation, and I post about it as a cautionary tale regarding doctors' ignorance to our special needs with SR meds.
