Yes, you can get Influenzinum online - check out http://abchomeopathy.com/flu.php
I have no financial connection with this company/website, but have ordered a few remedies from them and have been completely satisfied with their service each time I've ordered from them.
I have not used Influenzinum, but have used Oscillococcinum as prevention; I seldom get the flu when I am good about
taking my weekly dose of Oscillococcinum as prevention (I only take 1 capful, not the whole tube like the instructions say...I'd only take the whole tube if I actually got the flu).
