The Invisible Man (2000)

The Invisible Man was created by Matt Greenburg and stars Vincent Ventresca as Darien Fawkes, a former thief who is released from jail in exchange for undergoing an experiment. This experiment involved the implantation of a "quicksilver" gland inside his head which secretes a substance called quicksilver, with light-bending properties that make him invisible.

Unfortunately for Fawkes' The gland's creator sabotaged his creation in a way that causes the release of a neurotoxin that builds up in his bloodstream causing pain and psychosis. The problem can be controlled with a counteragent but his supply is controlled by a government agency who wants Fawkes to work for them and opposes the removal of the gland which they consider highly valuable.
