Famous parents don't always make for a charmed life. Since Sage Stallone's death last Friday, details have emerged that suggest the 36-year-old son of Sylvester Stallone may not have been in the best place in the weeks leading up to his tragic passing.
On Tuesday, the Stallone family met with the Los Angeles County Coroner's Office, a source familiar with the case told ABC News, and expressed concern that Sage Stallone may have been overmedicated prior to his death.
Sage Stallone's mother has hinted at the pain her son dealt with prior to his death. Weeks before he died, she begged him not to undergo extensive dental surgery.
Sasha Czack, Sylvester Stallone's first wife, told the New York Post that her 36-year-old son was on pain pills at the time of his death after having had five teeth pulled. The extractions took place two weeks before he was found dead in his Los Angeles-area apartment Friday.
Czack said she advised him not to get the surgery, telling the Post, "I told him not to do that. I've heard about people dying having multiple procedures done to your mouth. Do not have more than one tooth [pulled]."
When the Post asked whether he was taking painkillers afterward, she answered, "Wouldn't you be?"
Some have also suggested that Sage Stallone was depressed. Sylvester Stallone's nephew took to Facebook shortly after Sage Stallone's death and accused his action actor uncle of cutting himself off from his son and not returning Sage Stallone's phone calls, according to posts obtained by Celebuzz. The nephew, Edd Filiti, later deleted those posts and said, via Facebook, that they were written "in moment of sheer panic."
It will take weeks to learn Sage Stallone's official cause of death, pending toxicology results.

Michael Blosil, the 18-year-old son of Marie Osmond and her ex-husband Brian Blosil, jumped to his death from the roof of his Los Angeles apartment building in February 2010. Blosil battled substance abuse and depression for much of his life -- he had his first stint in rehab at age 12, and first tried to commit suicide after his parents' divorce in 2007.
"I was going through a very public divorce, going through custody battles. My dad died, and my son went into rehab," Osmond told Oprah Winfrey in November 2010. "He couldn't deal with it. He promised he would never do anything like that again, and I believed him."
Osmond said that in the weeks leading up to his death, Blosil seemed happier than ever, but the night before his suicide, something was off.
"I had spoken to him the evening before, and it was concerning to me," Osmond said. "It was the first time I heard him cry and say he felt alone and that he had no friends."
Bloggers speculated that Blosil was gay, and a struggle with his sexuality may have contributed to his depression. Osmond told Winfrey that wasn't the case.
"My son was not gay," she said. "He wanted to be married and have a family and travel all over the world. And it wouldn't matter if he was. I have a daughter who is gay, and it was my daughter who was offended by it, like, 'What? All gay kids commit suicide?' She really wanted it cleared up."
Mackenzie Phillips, the daughter of the Mamas and the Papas stars John and Michelle Phillips, has long struggled with drug addiction that began when she was a teen star on the hit sitcom "One Day at a Time." After a life marred with drug abuse and arrests, Phillips dropped a bombshell in 2009 when she told Oprah Winfrey that her father had raped her when she was 18 and for the next 10 years they carried on a consensual sexual relationship.
Redmond O'Neal, the son of Ryan O'Neal and the late Farrah Fawcett, also has a long history of substance abuse problems and arrests. With his mother dying, O'Neal was released briefly from prison, where he was serving time on drug charges, to see her for the last time. "Redmond, his feet in shackles, is briefly released from prison and led into his mother's bedroom, where he lays his head on her chest, telling her how much she means to him," his father Ryan O'Neal wrote in his new book "Both of Us."
Later, his father would deliver the news to him of his mother's death while he was behind bars. Now 27, O'Neal was recently praised by a judge for his progress in a drug treatment program. The judge has said he would delay sentencing O'Neal for a probation violation following his 2011 arrest for heroin possession as long as he stayed clean. O'Neal's older half-sister, Tatum O'Neal, also detailed her battle with drug addiction in her memoirs "A Paper Life" and "Found."
In 2010, Cameron Douglas, the only son of actor Michael Douglas and Diandra Douglas, was sentenced to five years in prison for pleading guilty to selling bulk quantities of methamphetamine and cocaine at Manhattan's upscale Hotel Gansevoort in 2009. His father, the Oscar-winning actor, pleaded for his son to get less jail time and ultimately got his wish. In a five-page letter to the judge, Michael Douglas wrote that his son had been in and out of rehab since he was 13, and Douglas blamed his family's history of addiction as well as his own fame and that of his father Kirk Douglas for his son's difficulty in finding his own way. He added, "Cameron grew up a single child in a bad marriage."
Nick Hogan, son of professional wrestling icon Hulk Hogan, made a name for himself as a race car driver while still in his teens. He appeared in the family's reality TV show, "Hogan Knows Best," which ran from 2005 to 2007. But it was need for speed off the racetrack that got him into big trouble. In 2007, Hogan was drinking and speeding when he crashed his Toyota Supra sports car into a tree and his best friend, John Graziano, was thrown from the passenger seat and suffered a permanently debilitating brain injury. Hogan accepted a plea deal for reckless driving and was sentenced to eight months behind bars. It was "absolutely reckless," he acknowledged in an exclusive interview with "Good Morning America" in 2010. "It was being young and honestly just stupid, not mature."
