Started feeling bad and different (more disoriented, numbness, sleep problems) a few days after my latest refill of metoprolol tartrate and now I notice pharmacy changed my generic brand from Mylan to Caraco. Pills look different but I've identified them as correct doses. I feel worse but I can't be sure that's it. I'm trying to get specific documentation from each manufacturer including side effect rates, but I can't seem to find it. Any advice? Anyone else had a problem with Caraco? Is there data sorted by manufacturer?
