Lamar Odom has been on life support in a Las Vegas hospital after he was discovered unconscious at a Nevada brothel on Tuesday. We reported earlier that Odom’s friends and family rushed to the hospital to be by his side, as the NBA star remains comatose.

Odom’s ex-wife, Khloe Kardashian, is currently supporting him at the hospital.

Khloe, her sister Kim Kardashian, and their mother, Kris Jenner, are all waiting to hear the fate of Odom, and are generally inconsolable. Kobe Bryant was also reportedly at Odom’s side, along with Rob Kardashian and Scott Disick. Bryant is one of Odom’s closest friends, and he drove to the Las Vegas hospital last night after his game ended.

Odom was at the Love Ranch in Crystal, Nevada for a period of four days before collapsing. He arrived on Saturday, and was discovered unconscious by a woman with fluid leaking from his mouth and nose. Odom had been staying with the brothel’s owner, Dennis Hof.

Hof reported that Odom seemed fine, but appeared quiet and withdrawn on Sunday. Odom was taking a vacation, and had come to Love Ranch to relax. He was rushed to a nearby hospital by ambulance, but transferred to a larger hospital in Las Vegas as his condition was quite severe.

According to a report from the Washington Post, Odom had taken a concoction of cocaine and 10 tablets of “sexual performance enhancer supplements” during his stay at the Love Ranch. Hof reported that Odom “was taking herbal Viagra and he was taking a lot of it.” Hof admitted to selling the supplements to Odom during his stay.

The pill was called ‘Reload,’ and gives users a rush of energy to combat erectile dysfunction. Hof explained that it was similar to drinking an energy drink in pill form. The FDA warns that it contained unknown ingredients that could lead to dangerous reactions.

According to a 2013 statement, “FDA laboratory analysis confirmed that ‘Reload’ contains sildenafil, the active ingredient in the FDA-approved prescription drug Viagra, used to treat erectile dysfunction (ED). This undeclared ingredient may interact with nitrates found in some prescription drugs such as nitroglycerine and may lower blood pressure to dangerous levels.” The FDA added that consumers should cease use of the product immediately and throw it away.

Odom is currently comatose and breathing with a ventilator, and is suffering complications related to his heart, kidneys, and lungs. Doctors remain uncertain about the cause of Odom’s collapse.
