SCP-500 is a plastic can containing 47 red pills. When consumed, these pills can cure any and all diseases infecting the user. Each SCP-500 pill is individually designated as 500-01 through 500-47. All attempts at synthesizing more of what is thought to be the active ingredient of the pills have been unsuccessful.
SCP-500 pills can be found near deceased guards, SCP-035's containment chamber, or the small room in the Maintenance Tunnels. SCP-500 can cure SCP-008, illnesses caused by SCP-1025, and any injuries the player has attained. Because of the small amount of SCP-500 pills that can be found in the facility, it is advised that SCP-500 should not be used unless the player's condition is critical.
- In the inventory, SCP-500 is fully red. However, when not in the inventory, it is both white and red. This is likely a bug.
- SCP-500, like SCP-008, was originally part of a third-party mod for SCP - Containment Breach made by forum user InnocentSam. After the game's creator Regalis played the mod, both were added into the game in the version 0.7 update.
- When SCP-500 was first added to the Foundation's SCP series in 2008, there were originally 59 pills in containment. The current number of pills currently stands at 47 due to 12 of them being used for various testing purposes.
