Kenyan marathoner Diana Kipyokei has been banned for six years and stripped of her 2021 Boston Marathon title for doping and tampering. The Athletics Integrity Unit says Kipyokei's urine sample after winning in Boston in October 2021 had traces of triamcinolone acetonide - an anti-inflammatory prohibited at races when an athlete does not have permission to use it as a medication.

Her sample taken in May in Kenya revealed the presence of furosemide, which is a diuretic."In her explanation, she claimed to have been prescribed medication by a doctor at a hospital to treat an ankle injury and presented supporting documentation. However, investigations revealed that, though Rionoripo was treated at the hospital, she had altered her prescription form to include Lasix (the commercial name for furosemide)," the AIU said.

Rionoripo could have been banned for six years but received a one-year reduction "due to an early admission and acceptance of the sanction," the AIU said.
