Do you have access to albendazole and pyrantel? Pyrantel will kill hookworm in dogs, but dogs have shorter systems than we do... it works in kids too but not sure about adults. You could proba ly do a 3 day round of albendazole without much liver stress. If you take it with ivermectin, it's amazing... but you have to take ivermectin on an empty stomach and albendazole with a fatty meal.
I have a ton of albendazole tablets that I've been sending to people but i don't know if they'd make it through customs. Normall I'll print "vitamin supplement" on a label and paste it over where it says "albendazole"
I'm assuming the EN on your name = England?
