I have migraines that have not been able to be controled by any procedures or meds except for the 200ug of Duragesic Fentynal that I have been on for over a year. The blood tests are fine, & I haven't had any migraine pain since I have used these patches.

I read the information pamplet from the pharmaceutical company that comes with the med to get as much information about it as I could. I read in it that there is a minimum weight that needs to be maintained. I have been losing weight & am afraid to ask this question of my pain specialist. I am curious as to what may happen when using this med at a weight lower than specified. I can't afford to mess up my ability to use this med but am having a problem controlling the weight loss
