The U.S. Anti-Doping Agency has suspended two-time Olympic medalist Dawn Harper-Nelson for three months for an anti-doping rule violation.
Harper-Nelson tested positive for hydrochlorothiazide and related metabolites in an out-of-competition sample she gave on Dec. 1. The drug is in the class of diuretics and masking agents.
Harper-Nelson, 32, explained that the positive test was caused by a blood pressure medication she was prescribed to treat hypertension. USADA said its investigation included a review of Harper-Nelson’s medical records.
It accepted Harper-Nelson’s explanation that she tried to determine if the medication contained prohibited substances but was unable to do so because she used partial search terms.
