Yes, you can use them all on the same day (though Panacur needs to be given 2x/day for 3 days in a row), and you can get concentrated piperazine in the product Wazine 34, which is a double-dose piperazine product, so do NOT overdose this one as it can give neurological problems.Originally Posted by warready
