Hello, you should expect a die off period of 3-5 days after administration of the medication. Because it is administered orally, most roundworms and hookworms begin to die almost immediately, but it may take up to 3-5 days to have complete clearance of worms. You may recheck a stool sample in 10 days to ensure there are not more parasites noted. Hope this helps and best of luck.
