According to the athlete.......
"I received a letter from the ITF that I failed a drugs test at the Australian Open.I take full responsibility for it.
For the past 10 years I have been given a medicine called mildronate by my family doctor and a few days ago after I received the ITF letter I found out that it also has another name of meldonium which I did not know.
It is very important for you to understand that for 10 years this medicine was not on Wada's banned list and I had legally been taking the medicine for the past 10 years.The International Tennis Federation [ITF] has confirmed that she will be provisionally suspended with effect from 12 March.
But on January 1st the rules had changed and meldonium became a prohibited substance which I had not known."
