i give up. i've searched all over the internet. My vet prescribed several different medications for an infestation of lice and worms and cocci, which i have already administered. i could find withdrawal times on the others, but not for the Pyrantel Pamoate. It is marketed by Vedco under the name Equi-Phar ProTal. It appears to be a horse dewormer. i probably should have searched for withdrawal times BEFORE giving the meds. But i trusted she knew what she was doing. Now my fear is that i've given my hens something that will keep us from eating their eggs for a very long time, if ever. Does anyone have any information on this? i would greatly appreciate any personal experience with the medication, and what you chose as the appropriate withdrawal time for you. Also, if anyone has information on a better dewormer to use in the future, i would greatly appreciate it.
