The comedian concluded with a tweet apologizing once again for her remark.
Ambien's manufacturer, Sanofi-Aventis, responded to the news on Wednesday, saying via Twitter, "While all pharmaceutical treatments have side effects, racism is not a known side effect of any Sanofi medication".
"I can't let myself cave in though", Barr tweeted.

Next came a doubles match with older sister Venus for the US Fed Cup team in February. As Barty said, "I think when push came to shove, the real Serena came out".
In another tweet Barr apologised to actor Jayden Rey, who played Mary Connor, the daughter of DJ and his African American wife Geena on the show.
She urged people not to defend her and said of her Jarrett tweet that she was "ambien tweeting" at 2 a.m.
In her controversial tweets, Barr had used Jarrett's initials and wrote, "Muslim brotherhood & planet of the apes had a baby".
Channing Dungey, the president of ABC Entertainment, issued a statement Tuesday calling Barr's tweet "abhorrent, repugnant" and announced the show "Roseanne" - which the network had picked up for a second season - was being canceled.
The ABC Network received plenty of praise for taking a stand and cancelling the cash-cow series, but it also left them in the awkward position of putting dozens of hardworking cast and crew out of a job. Tweeted Trump: "Maybe I just didn't get the call".

She claimed she was joking, but then she deleted the tweet and issued an apology to Jarrett and "all Americans". The Weinstein Company asked for Moore to repay $2m for the costs they had already incurred on it.
Barr served as a star and executive producer on the ABC show, which was a ratings phenomenon when it returned to U.S. television earlier this year for a 10th series, after its original run came to an end in May 1997. Hours later, however, Barr was back on social media, lashing out at colleagues sharing their views on her racially charged comment.
She has a history of diving into political conspiracy theories on Twitter, and that's how she ended her Memorial Day weekend.
"I think it was a reasonable bet to take, and it worked until it didn't", Ancier said. What she did and what she said is totally wrong.
Now, US president Donald Trump has weighed in on the matter and, well, it's possibly the most self-indulgent thing we have read in a long time.
That includes rumors and speculation that the show could possibly continue in the future in the form of a spinoff, if Barr's titular character was written off, and the focus was shifted to Goodman's character.

An extraordinary flurry of diplomacy since then - much of it led by South Korea - appears to have put the meeting back on track. He's a longtime Korean intelligence official with past involvement in many violent acts, and now he's heading to the U.S.
In addition to the cancellation of her rebooted show, reruns of the original program, which ran for much of the 1990s, were pulled by Viacom.
