I know of no medication that could possibly have such a side effect. Of course I am no pharmacist but I have studied some nursing and pharmacology and while some drugs do affect skin and pigmentation, none do so in such a dramatic way.
Think of it, if it were true those drug companies would have sold it to us humans in no time! Take a pill to change your hair color, no roots! Bling bling bling!!!
Would love to know if anyone here that works with vets could ask so we would know for sure?
