Oh. So... is it your Pokémon or your friend's? I don't know much about creatures in this world, but I do know that caffeine in general isn't good for most back home. There are some that can tolerate it. Pokémon, however, do seem to be fairly hardly, considering they enjoy battling and often have special powers. Perhaps it will tolerate it well? I'd make sure to keep a close eye on it and watch for any unusual behavior. Also, your friend may want to try asking at a PokéCenter, just to be sure.
