I'm going to do the 14 days just to be safe. Then 14 off. I may possibly do a third round after that if I think it's needed. I took the ivermectin for whatever the tiny black hairlike worms were. That seemed to work for them. The Albendazole is for the hookworms and pin worms or whatever they are. They seem like extra hardy superman mutant pin worms that just don't die without prolonged meds. I don't want them to ever come back.
