Your information is wrong. You are confusing Nexavir, an antiviral and anti-inflammatory, with Nexavar (sorafenib), a cancer treatment. Nexavir (note the "vir" at the end, that indicates virus) is a liver-derivative complex with no reported side effects in its more than 80 years of use. Nexavar is chemo, and I'm not surprised it causes convulsions. You should correct this.
