I took a bad drug for spasms for years, Meprobamate. At first it worked well, but then my neurological symptoms got a LOT worse, and a new doctor thought it was the Meprobamate. I had trouble getting off the Mepro--but finally switching to Klonopin ended the problem. I HAD to take the Klonopin to get off Mepro, it was the only way. I do believe the Meprobamate worsened my condition badly, but the damage didn't show up for years, which is a different situation than with most meds for me. My little son was asking me to get off the Mepro for years, and he was so right.
