Spokeswoman Debby Simms says Brazeau was not arrested as some early media reports suggested, but that someone else at his home in Gatineau, Que., had a private medical situation that has since been resolved.
Simms says most people believe medical information should be kept private.
Police in Gatineau, Que., say they responded to a call for help in the wee hours of Tuesday morning.
They would not confirm that the 38-year-old senator was involved, but referred to an address associated with him.
Simms said that the situation was chaotic, and that some may have mistakenly believed Brazeau was the person in distress.
Brazeau was kicked out of the Conservative caucus earlier this year after he was charged with assault and sexual assault. He is set to appear in court on Wednesday.
The Senate is also holding back some of Brazeau's wages to repay $48,000 in disallowed housing expenses.
