I have a couple of questions for anyone who can help me. What is "herxing"? Also, has anyone who was previously on Kutapressin tried Nexavir and had good results? What about the transdermal form? And why was Kutapressiin taken off the market? I used it in the early 90s and had really good results with sore throat, fever, sore lymph nodes but stopped taking it because I couldn't afford it anymore. didn't know it was takne off the market. Anyone know why??
