I have been taking this drug for two weeks. I dont know if it's the side effects, panic attack. A combination of both. Or God forbid the myasthenia Gravis is being affected by it. I was approved to take it by my MG specialist, a liver specialist, and a respirologist. Im 70 years old and it would be great to clear this virus. My symptoms are a clogged nose, dizziness. and, feeling of being exhausted,like my breathing just recently, like maybe several days. I take nothing for my acid reflux. I take 15mg of predisone everywhere day. I got this virus from a cosmetic procedures in1998, lucky me. I'm on the verge of stopping this harvoni because everyone I talk to knows nothing about this. Can anyone give me any info about this combo. Thanks. Darlene
