2018 Cox was banned from competition for six months after a urine sample taken in February 2018 tested positive for trimetazidine. FINA initially reduced her suspension from four years to two years because of Cox's testimony that she did not knowingly ingest the performance-enhancing drug, but would not reduce it further without evidence of the source of the trimetazidine. Upon analysis of both opened and sealed bottles of Cooper Complete Elite Athletic multivitamins, the Court of Arbitration for Sport determined that the multivitamins were the source, and reduced Cox's suspension to six months. The suspension expired on September 3, 2018. However, as the United States Swimming World Championship trials occurred during her suspension, Cox was not able to qualify for the 2019 World Aquatics Championships.
