I would read the dosage chart and find out how much to take just like the animal . For example; one dose per body weight.
You might have to wait 3 months to take it again.
I know Darish sweden got rid of his flukes using Fasinex.
You will have to retrieve his protocol.
But I think he only took 1 tablespoon and waited 3 months and took it again.
Everyone is different, 4 days may be too much.
Read the directions first.
Today, many Dr.s are returning to animal meds and the cure rate is higher.
There are many articles on medscape using ivomec injections and then proceed with human albendazole with higher cure rates because the meds are not absorbing like they should.
