Powell had been part of the Wales squad which won 31-24 against Scotland at the Millennium Stadium on Saturday night.
A Welsh Rugby Union statement said: “We take matters of player conduct extremely seriously and have been happy with the professionalism and discipline of this squad in general terms.
“Andy knows he has misbehaved and is apologetic, but he also knows that he must take responsibility for his own actions and accept the repercussions.
“The player has made his private apologies to the Welsh management team as well as apologising in a public statement and we have also asked him to apologise to the Vale Resort Hotel, before asking him to leave the squad.”
