Nope @Inspectrcalahan and it's wildly improbable too.

Not impossible though. The "overdose" margin on this drug is crazy-high compared with most pharmaceuticals that have a safety margin of somewhere between 2:1 and 4:1; best I can determine it's at least 10:1 and perhaps as high as 100:1 (!!) This is why non-medical personnel hand it out in Africa among other places; if someone accidentally gets two or three doses instead of one the odds of it harming them are basically zero, and the serious interaction list is small enough that a quick question or two is all that is required.

BUT -- there ARE combination formulas (with other things in them; Heartguard being one!) and "pour on" and similar formulations intended for topical use. Those, if ingested, could be VERY bad news. I have zero information on any of them in terms of potential human toxicity and no any intention to run any of that down since you have to flat-out NUTS to consider consuming any of them, and if you ARE crazy, well, then you get what you get.
