According to the ruling, Safinova would lose her 2010 European title, 2011 world title, 2012 Olympic gold and 2013 worlds silver medal.
She is the latest in a growing list of Russian athletes to have past Olympic medals taken away over doping, as the nation struggles to overcome its most widespread doping scandal ever.
The Lausanne-based Court of Arbitration for Sport (CAS) said there was "clear evidence" that Savinova-Farnosova was involved in doping from 2010 until 2013 - including for the 2012 London Games.

Semenya will also become a two-time world champion if she is awarded Savinova's gold from 2011.

The Moscow drug-testing laboratory was later shut down and its director testified he had covered up hundreds of failed tests by top Russian athletes.

Another Russian finalist from the 2012 final, Yelena Arzhakova, has already been banned and Ekaterina Poistogova, who took the bronze medal, is under investigation for doping.
