Dear Concierge Members:
I will review below the scientific data available for Nexavir for both its FDA approved uses in inflammatory skin disorders and its non-FDA approved uses as an anti-viral and its clinical effects in CFS cases.
At the center of Nexavir’s scientifically studied benefits to CFS cases are two articles,
I have reviewed both articles with perhaps the DNA Sciences paper the most extensive and adds laboratory proof of a Kutapressin (aka Nexavir) benefit as well as a better therapeutic design which gave an 85% response rate described as good to excellent and a 13% modest response rate and a 2% nonresponse rate including a roughly 1% negative response (5 cases out of 600 treated).
The improved response was primarily due to at least a 6-month long therapy of at least 2 ml per day injected by IM. SQ is allowed but a slightly greater degree of initial problems was seen, probably due to the immune activation present in CFS and which is more easily induced further by SQ injection compared to IM.
Background of Kutapressin (aka Nexavir), an injectable liver extract originally developed by Kramers Urban, now Schwartz Pharma, Mequon, WI and whose rights were sold to Nexco-Pharma, Houston, TX in 2003 with a name change to Nexavir.
The key difference in the 1992 study besides the SLIF assay was that the protocol was more aggressive using up to 2 ml of IM injections for 6 months and then a slow taper to 2 ml IM twice a week for a month and then 2 ml once a week for a month and then off. If there is a relapse, then going back to 2 ml daily for 10 days before resuming the original taper.
The results of the 1992 study of 130 CFS cases were that 85% had a good to excellent response with return or near return to normal daily activities and 13% additional CFS cases had a moderate response but unable to return to normal daily activity and 2% failed to respond with perhaps half of those or 1% with a negative response.
Nexavir is a notably safe drug used for over 70 years. It has very useful anti-inflammatory, anti-viral and immune-regulating benefits. On the downside, it is relatively costly at roughly $300 per month per ml used once a day with a cost of $600/month minimum for 2 ml daily and this is wholesale cost (most of the patients paying $225 for 20-ml vial) which Dixie can obtain for my patients directly from Nexco-Pharma. I would recommend SQ self-injection into the lower abdomen using a pinched skin routine of self-injection with two back-to-back 1 ml injections daily using a 31 gauge, 1 ml insulin syringe. The first injection should be 0.1 ml SQ to make sure you tolerate Nexavir. Nexavir is also available as a skin paste at about $425 (wholesale price, retail price is $475) per month but is less effective in my experience, but a lot of my patients think it works as good as the injectable. Some of them do both (injectable and Cream for the first three months, but it gets very expensive)
