Danish tennis star Caroline Wozniacki has urged her fellow professionals to thoroughly check their medication following Maria Sharapova's failed drug test.

Sharapova revealed on Monday that she tested positive for meldonium after getting knocked out of the Australian Open by Serena Williams in January.

The five-time Grand Slam champion claimed that she had been prescribed the medicine for the last 10 years, but the substance was added to the World Anti-Doping Agency's banned performance-enhancing drugs list at the start of 2016.

During a press conference at Madison Square Garden in New York ahead of an exhibition match against Williams, Wozniacki gave her reaction to the news.

The 25-year-old told reporters: "Any time we take any medication I think we double and triple and quadruple check because sometimes even things like cough drops and nasal sprays can be on the list.

"So I think as athletes we always make sure to really make sure there is nothing in it that could put us in a bad situation."

Sharapova will be provisionally suspended by the International Tennis Federation from March 12, and is facing a four-year ban.
