The Yubileyny Sports Palace ice rink then closed for renovations, forcing the pair and Moskvina to relocate to Hackensack, New Jersey's Ice House in the summer of 1999. Berezhnaya/Sikharulidze struggled at Skate America in October 1999, placing third, but regained their form to win Skate Canada in November. Moskvina would later admit Sikharulidze had become distracted by life in a new country and was not as focused on training. In February 2000, the pair won gold at the 2000 Europeans but were stripped of their medals after Berezhnaya tested positive for pseudoephedrine, a substance whose ban was lifted temporarily between 2004 and 2010 before being banned again. This resulted in a three-month disqualification from the date of the test, and the medal being stripped. She stated that she had taken cold medication approved by a doctor but had failed to inform the ISU as required. The pair missed the World Championships that year as a result of the disqualification.
