(REUTERS) - Tennis star Maria Sharapova has revealed that she failed a drugs test at the Australian Open.
The Russian former world No. 1 announced at a press conference that she had tested positive for meldonium, a substance she has been taking for the last 10 years for health reasons.
Meldonium became a banned substance earlier this year, something the five-time Grand Slam champion claimed she had no knowledge of.
The 28-year-old five-time grand slam champion will be provisionally suspended starting March 12, the International Tennis Federation (ITF) said.
"I failed the test and take full responsibility for that," said a solemn Sharapova.
"I had been taking this medicine for the past 10 years, but on 1 January this became a prohibited substance which I did not know."
She said she was prescribed the drug in 2006 after suffering from irregular heartbeat and displaying early signs of diabetes.
"I received an email on 22 December from Wada (World Anti-Doping Agency) about the changes happening to the banned list and you can see prohibited items, and I didn't click on that link."
Sharapova, who has been struggling with injuries, said she does not know what sanctions she will face, but hopes to return to tennis in future.
"I made a huge mistake," she said.

She is the seventh athlete in a month to test positive for meldonium, which is used to treat diabetes and low magnesium, and was only banned by the World Anti-Doping Agency as of Jan 1. “I made a huge mistake. I let my fans down and I let the sport down,” said Sharapova, a teenage tennis prodigy who became the third-youngest Wimbledon champion. “I take full responsibility for it.” “I know that with this I face consequences and I don’t want to end my career this way. I really hope that I will be given another chance to play this game,” former world No.1 Sharapova told a news conference in a downtown Los Angeles hotel.
The ITF’s anti-doping program calls for a four-year suspension for a positive test, but that ban can be reduced in various circumstances, such as for first-time offences or if the player shows no significant fault or negligence. If a player bears no fault or negligence, there is no suspension.
According to Forbes, she earned $29.5 million in 2015, mostly from endorsements.
Sharapova said her family doctor had been giving her mildronate, which is also called meldonium, for 10 years after she frequently became sick, had irregular EKG results, a magnesium deficiency and a family history of diabetes. “It is very important for you to understand that for 10 years this medicine was not on WADA’s banned list and I had been legally taking the medicine. But on January the first, the rules have changed and meldonium became a prohibited substance.” The World Anti-Doping Agency, or WADA, declined to comment until ITF issues a final decision.
Meldonium is used to treat chest pain and heart attacks among other conditions, but some researchers have linked it to increased athletic performance and endurance. It is listed by WADA among its prohibited metabolic modulators, along with insulin, and some researchers say it can also help recovery.
It is not approved in the United States but is available in Russia, Latvia and other countries in that region. Over the past month, Russian cyclist Eduard Vorganov, Russian figure skater Ekaterina Bobrova and Ethiopia-born athletes Endeshaw Negesse and Abeba Aregawi and Ukraine biathletes Olga Abramova and Artem Tyshchenko have all tested positive for meldonium.
Sharapova is the most prominent tennis player to test positive for a banned substance in recent years.
Croatia’s Marin Cilic was banned for nine months in 2013 after testing positive for a prohibited stimulant, though the suspension was cut to four months on appeal.
Former No. 1 Swiss player Martina Hingis retired after receiving a two-year suspension for a positive cocaine test in 2007, though she denied taking the drug.
Last year, the sport banned U.S. player Wayne Odesnik for 15 years after his second doping violation, testing positive for steroids and other banned substances
Sharapova is the biggest name in sport to test positive since New York Yankees baseball slugger Alex Rodriguez was banned for a year in 2013 after using performance-enhancing drugs and American cyclist Lance Armstrong was banned for life from racing in 2012 after a U.S. Anti-Doping investigation.
Sharapova, one of the most popular figures in global sports, has long been a favourite with her sponsors. Cosmetics maker Avon Products Inc declined to comment on its endorsements. Nike Inc, the world’s largest footwear maker and another sponsor, did not immediately respond to a request for comment.
Steve Simon, CEO of the Women’s Tennis Association, said in a statement he was saddened to hear the news. “Maria (Sharapova) is a leader and I have always known her to be a woman of great integrity,” he said. “Nevertheless, as Maria acknowledged, it is every player’s responsibility to know what they put in their body and to know if it is permissible. The WTA will support the decisions reached through this process.” The news came a day after Sharapova’s management team said she was going to make a “major announcement,” which had many speculating that she was going to announce her retirement from professional tennis.
Sharapova, who has struggled with a series of injuries in recent years, has not competed since she lost to Serena Williams in the quarter-finals of the Australian Open in January.
Renowned for her never-say-die approach, a gritty baseline game and high-decibel shrieking, Sharapova at 17 became the first Russian woman to win Wimbledon when she beat Serena Williams 6-1 6-4 in the 2004 final.
That victory also made her the third-youngest Wimbledon champion, behind only Lottie Dod and Martina Hingis, and the fourth-youngest grand slam winner in the open era after Hingis, Monica Seles and Tracy Austin.
