I had surgery 2 months ago and have been taking vicodin 5mg for the past 3 weeks. My doctor just prescribed Ryzolt to replace the vicodin and I took my first one today and find that it worked for approx. 8 hours, but that now I am in pain. Can I take mortin or an over the counter anti-inflamatory or pain reliever while taking Ryzolt. And will Ryzolt build up in my system and relieve the pain for longer periods of time, the longer I take it?
