(CNN) - Rep. Patrick Kennedy, the Rhode Island Democrat who in 2006 checked into a rehabilitation center for drug addiction following a car accident on Capitol Hill, is again seeking medical treatment.
In a statement issued by his office Friday, the son of Massachusetts Sen. Ted Kennedy said, "I have always said that recovery is a life-long process and that I will do whatever it takes to preserve my health."
"In consultation with my doctors, I have decided to temporarily step away from my normal routine to ensure that I am being as vigilant as possible in my recovery," he said. "I hope that in some small way my decision to be proactive and public in my efforts to remain healthy can help remove the stigma that has served as a barrier for many Americans reluctant to get the help they need."
The Providence Journal reported Friday Kennedy has "entered an undisclosed medical facility for treatment."
After crashing his car into a Capitol Hill barricade in 2006, Kennedy admitted to an addiction to prescription medication and spent a month in a rehabilitation center in Minnesota.
