I had a patient come in with Zimectrin Gold (for horses) and said he had been using it to “stay safe.” It has a combo of two wormers. The first one is safe for humans (has been used for decades and won the Nobel prize), but the second one is used for specific parasites in humans (I have never prescribed it).
First, hopefully people have a doctor who is willing to prescribe the first med in tablet form, for humans, if they decide to take it.
Another issue with humans buying the paste form… When I ordered this med for my horses to worm them, it seemed a lot more expensive these days!!
