Prohibit Soluble Drench Powder is a water-soluble anthelmintic powder built around levamisole hydrochloride, formulated for oral use in beef cattle and sheep. The powder is reconstituted with a specified volume of water to form a drench solution, which is then given with a standard drench syringe or dosed through an automatic drenching syringe. It is labeled to address a broad range of stomach, intestinal and lungworm species affecting both cattle and sheep. Careful weight estimation is required before dosing since underdosing can reduce effectiveness and contribute to parasite resistance. Once mixed, leftover solution can be kept in a tightly closed container for later use within the labeled storage window. The product carries defined pre-slaughter withdrawal periods for cattle and sheep and is not intended for dairy animals of breeding age.
