After the game, Braun said his dizziness was the result of fluid in his ear.
"I had fluid built up in my left ear and got some medicine. I should be fine," Braun said. "That's what caused me to be dizzy and light-headed."
Braun, who is hitting .261 with 13 home runs and 40 RBIs, left the game having gone 0-for-2 with a strikeout.
He was removed in the sixth inning when Hernan Perez pinch hit for him.
The 31-year-old slugger has previously dealt with dizziness; in 2008, he battled an inner-ear infection.
Brewers manager Craig Counsell said Braun is "day to day."
