A police department spokesman says a preliminary test of the powder indicated it wasn't dangerous.
Police say Vanessa Trump called 911 Monday morning after opening a letter addressed to Donald Trump, Jr. at their midtown Manhattan apartment.
Police say she said she was coughing and felt nauseous.
The Trump Organization didn't immediately respond to a request for comment.
It's unclear what the powder was.
CNN reported that two other people at the residence were also taken to a hospital.
Detectives from the New York Police Department's intelligence division and Secret Service agents are investigating.
A spokeswoman for the Secret Service hasn't responded to a request for comment.
Police say a hazmat unit was also at the scene.
Trump, Jr. says he's thankful that his wife and children are "safe and unharmed" after an envelope containing white powder was sent to his mother-in-law's New York City apartment.
In a statement posted on Twitter, the Republican president's son said the incident was "truly disgusting."
