I was prescribed Nucynta but I was reading that it may cause seizures and I am allergic to Tramadol and have had seizures when I was on that. It worries me that I read tapentadol and am afraid that it's in the same family as Tramadol. Am I right? I haven't taken any yet but I don't want another episode of another grand mal seizure. Any immediate answers will be greatly helpful. I a currently on 325mg Norco and was told not to use at same time as Nucynta.
