BIG] I agree, you have to be careful with OTC stuff. If the bottle says 1% solution, however, the over-the-counter Ivomec is exactly the same concentration we use at the vets' I work for-in fact, we use the Ivomec brand itself; it IS marketed as a horse medication in that form. Just an FYI! This is why I listed the concentrations of everything-lots of times when people post med dosages on the list, they only give the AMOUNT they're giving, i.e. "0.2 cc of prednisone," but not the dose-"0.2 cc of prednisone"-means nothing if you don't know the concentration, i.e. "2.5 mg/ml, to give 0.5 mg of prednisone with each 0.2 cc dose.") Thought I'd share! :) -April [Posted in FML issue 4285]
