http://pets.stackexchange.com/questions/695/can-i-give-human-medicine-to-chickens is the question that has caused me to ask this.

I answered the question saying that any human medicine should be prescribed and monitored by someone with direct knowledge of the situation. Granted, I have no proof to back up my "claim" that human medicine is bad for animals across the board. But my worry is that we're going to start a trend of "Is {drug} safe for {animal}?". To me, it could become a scary situation when someone two years from now could stumble on the post and give the drug to their animal and do serious harm to it because it reacted differently.

So how should we handle these questions as the community grows?
