U.S. Paralympic Track & Field Athlete Breanna Clark Accepts Public Warning

An empty track on a blue sky day.USADA announced today that Breanna Clark, 28, of Los Angeles, California, a Para athlete in the sport of track and field, has accepted a public warning after testing positive for hydrochlorothiazide (HCTZ), a prohibited diuretic. After a thorough investigation, USADA determined that Clark’s violation occurred when a family member responsible for Clark’s care, including medication dispensing, accidentally gave her their own HCTZ medication when arranging her daily vitamins. The HCTZ medication closely resembled two of Clark’s daily vitamins.

Because Clark’s positive sample from March 7, 2023 was collected out-of-competition, there are no competitive results to disqualify.
