A lawyer for the hip-hop star, 55, said on Saturday that he was now back at home, without giving further details.
A day earlier, actor and rapper Ice-T said he had spoken to Dr Dre, describing him as "safe and looking good".
TMZ reported on 5 January that Dr Dre had been taken to Cedars-Sinai Medical Center in Los Angeles, California.
Dr Dre's team later issued a statement saying the rapper - whose real name is Andre Romelle Young - was in a stable condition.
"Thanks to my family, friends and fans for their interest and well wishes. I'm doing great and getting excellent care from my medical team," a post on his Instagram read.
"I will be out of the hospital and back home soon. Shout out to all the great medical professionals at Cedars. One Love!!"
