yup- have been telling people, and even those with a MASTERS IN PUBLIC HEALTH that people have been taking this drug for 40+ years. Why don't they know this and why is it being kept from being prescribed by Drs. I hear pharmacies won't fill the Rx. Guess I am headed to the Feed/Tractor store if I get sick! (I had some on hand as I was giving it to a mangy coyote for a long time- needed to replenish my stock much earlier I guess!)
