"i&#039;ve had chronic back/hip pain for over 10 years.  i&#039;ve recently come of fentanyl patches and needed something to keep the pain at bay.  i started on 50mg nucynta 2x a day and was miserable.  after much begging the pain management centre agreed to see me after a week.  they switched me to nucynta er 100mg and life is much better.  i still have breakthrough pains 1 to 2x a day, and hope to address this when i return in to pm in july.  however, this is working as well as fentanyl did. grateful for the &quot;coupon&quot; provided by the manufacturer, otherwise this would be an expensive treatment."
