My health insurance no longer will cover the ONLY medication that helped me with fatigue and the ability to stay working in full time status. The Brand name Nuvigil I guess costs too much and now that Mylan has come up with a generic form it's the only one available to me. I'm back to square one 4 yrs ago after discovering this awesome medication that is time released so that I don't have huge ups and downs of fatigue throughout the day. I could keep going from 4 am till 8 or 10 pm without falling asleep watching TV or just sitting on the sofa after working a full day. Now I'm back to taking a nap during my lunch break (if I get one) and then come home so fatigued I am unable to even cook dinner. It's not the kind of like I was living anymore for the past 4 years and I really don't want to go back to that. So for the past 3 months I've not been taking anything because the generic brand did not have the same positive affects as the brand nuvigil. It made me jittery, on edge, emotional and sad, nauseous, headaches and had no effect on my fatigue. Why are the drug companies acting as if they are my doctor and can just erroneously change my medications prescribed by my physician and deny the pre-authorization he wrote for me to continue taking the brand name? This is "my life" not the drug company. It's one of the reasons I'm planning to retire because my job is so stressful and I am on multiple deadlines that I can no longer accomplish if I'm too tired to think. I've been struggling with this issue with my supervisors for almost 2 yrs now even though they know I have MS they don't care. They expect me to be able to perform the same way I have for years and I was able to until I became very ill in 2014 with unrelated issues with my stomach. After gallbladder surgery and then multiple EUD/ERCP follow up procedures I am unable to recover like someone without MS.
