The West London rivals meet at Craven Cottage this Saturday with the Hoops bottom of the Premier League and still searching for the first win of the league campaign.
Sidwell's fourth goal of the season helped Fulham return to winning ways when they beat Newcastle at Craven Cottage on Monday night, ending a run of seven games without a victory.
History is in Fulham's favour, with the Cottagers having not lost to QPR since May 1983 and Sidwell is determined for that record to continue.
"They have not won a game all season and we do not want it to be against us," declared the midfielder.
"We cannot let the occasion get to us. Before the Newcastle game, we knew it was massive. We had to get three points."
