Australian swimmer Emily Seebohm is among the latest batch of athletes to have their therapeutic use exemptions (TUEs) leaked by hackers.
In the sixth tranche of personal records released by the group called Fancy Bears, the multiple world champion and Olympic medallist, who has previously been in hospital due to asthma, was shown to have used prednisolone, a common treatment for the condition.
English double Olympic triathlon champion Alistair Brownlee also featured on the list leaked on Monday, with the Briton explaining the drug he used in 2013 was to treat altitude sickness.
Brownlee was revealed to have used acetazolamide, banned by WADA, on October 10 and 11 in 2013, having been given an exemption by UK anti-doping.

The 28-year-old said last week he had one TUE for the drug after suffering altitude sickness while climbing Kilimanjaro and reconfirmed that in a tweet on Monday.
Brownlee, who was widely praised for his sportsmanship after stopping to help stricken brother Jonathan over the line in the final Triathlon World Series event of the season last month, made reference to the event in a second tweet.
"Slightly embarrassing that someone as fit as me suffered from altitude sickness but thankfully @jonny_brownlee was there to carry me," he wrote.
British Triathlon also issued a statement in response to the leak, saying: "Let's be very clear; athletes who have a TUE on their record have followed the rules based on a specific medical requirement. We can say with absolute confidence that our athletes have nothing to hide.
"This attack on the integrity of athletes is shocking. We strongly condemn actions of this nature and continue to be in close contact with UKAD and WADA in regards to this matter."
