ok, now this guy knows about medacataions.That's a fairy tale and the overuse of meds like these cause restitant strains of bacteria and parasites.
Esha 2000 is a Dutch med from the 60tees / 70tees and the overuse overhere caused it hardly to do anything.
But to be honest : It is used as anti fungus med, so in this case I'd use it if there isn't anything else on hand.
