Nucynta although synthetic and has a half life of 4 hours will show up as a class 2 narcotic in a urine test. However don't count the half life in terms of it not being detected.Multiply the half life times 4 and then it will be 99.9% gone from your body.So at 50mg that would be roughly 7.4 days. 4 people found this useful.

Answers from Jacqueline M. Thielen, M.D. Premenstrual dysphoric disorder (PMDD) is a severe, sometimes disabling extension of premenstrual syndrome (PMS). Although regular PMS and PMDD both have physical and emotional symptoms, PMDD causes extreme mood shifts that can disrupt your work and damage your relationships. In both PMDD and PMS, symptoms usually begin seven to 10 days before your period starts and continue for the first few days that you have your period.
