The following year she won the silver medal behind Maria Laura Almirão at the 2005 South American Championships in Athletics, and joined her compatriot to win the relay gold. More relay success came at the 2005 World Championships in Athletics, as a team of Almirão, Coutinho, Josiane Tito and Lucimar Teodoro set a South American record time of 3:26.82 minutes in the heats, although they were disqualified in the final. She was a finalist in both the 200 metres and 400 m at the 2006 Ibero-American Championships, but she then disappeared from international competition with sub-par seasons in 2007 and 2008.
