Good catch, Gaj. AHIST is in fact Chlorcyclizine - and while Drugs.com referred to the brand name AHIST, they seem to have erroneously listed side effects for a completely different drug - "Chlorpheniramine". They should be notified about this, and I will email them later today.
It appears Sonix may have looked at the same result I did when I posted the Drugs.com listed side effects. A brief search of other sources for information did not turn up any dire warnings about the same sorts of intense hallucinations one might experience from Datura, which is common here as 'Jimson Weed' (colloquially "Loco Weed"). However, the precautions, and side effects I am reading about seem similar to those for Pseudoephedrine, and other powerful antihistamines, so obviously clearly not equivalent to 'Loco Weed'.
I think it is fair to assume that any drug powerful enough to potentially suppress the replication of HCV is going to have side effects, and possibly serious side effects.
Once again, I am theorizing here, and I not in any way suggesting, or recommending that anyone should take this medication unless expressly advised to to so by their physician.
Medical advice should absolutely be sought, and common sense and an abundance of caution should be exercised when exploring any new treatment option. The point I want to make is that given the research, I think Chlorcyclizine is worth an eye level look, and should not be dismissed out of hand, or inaccurately characterized.
Alarmist statements aren't particularly helpful or truly informative. We owe it to ourselves to simply explore the facts.
