That's just not something you really have to worry about. If it came from a pharmacy, the chances of it being fake are slim to nil. On the off-chance it is
fake, you can be sure as shit you can return it for the correct prescription.
It would be one thing if it were purchased on the street, but the likelihood of getting a fake medication from a pharmacy are ridiculously low. They could get in so much trouble it would make your head spin. Sure, mistakes are made every so often but when they are, they are fairly easily rectified. Try not to worry.
The pill ID confirms this is hydrocodone
and it was obtained from a pharmacy. I can almost guarantee you that you don't have fake pills. Honestly, there's not much else to say about it.
