Thanks for the info Positive Mind. I'll add some yogurt to my meal for the extra calcium.
I don't have any Albendazole at the moment. Valbazen is impossible for me to get anymore since Allivet stopped doing international shipments. I'll have to make do with fish prazi for now.
I'm going to do 50mg / kg in one day treatment (possibly divided between two meals). Then follow up 10 days later with another go. I read a study that seems to suggest that's optimal because prazi has little effect on H.nana eggs or juveniles.
