weird anti fungul spray

[Misaki]

Hello,

 

I own a cat and her immune system is not that much so she often get sick(skin problem, ear mite etc')

Now she got mange or ringworm or I lost count...

I took her to this new vet that is close to my house, she made a full review examining the cat for a long time(and cost me 2500 baht)

eventually she took samples and gave me this spray that treats fungal infection(brood spectrum).

Now, I'm a bit courtois guy so i decided to check this spray online.

 

that's what i found(exact product): http://ezuneed.com/product/mycoril-spray/

 

For what I can tell, this spray is for humans, so why did she gave it to me to treat my cat?

Is it a thing to use human medicine on pets?
