I take the Safegaurd Fenbendazole horse paste, with one tube giving me about 5-7 doses, just one dose per day. ICU and Scabdraggr protocols recommend a fatty diet during use, for improved absorption. It's never upset my stomach when taken without food, but my liver sometimes hurts just minutes after dosing.
I also use the Equimax Ivermectin paste, which is mixed with Praziquantel.
Nobody recommends this, but I really like to leave the paste under my tongue for a couple of minutes before swallowing. The fact that I love the taste of these pastes might suggest that I really benefit from these meds.
