Management requires treatment for the underlying cause. The majority of cases, the specific cause of pericarditis is not identified, therefore they are assumed to be caused by Coxsackie B virus and treated with NSAIDs. Colchicine has been proved to decreased the recurrences.

Educational Objective: NSAIDs, such as indomethacin and aspirin, are the best initial therapy for acute pericarditis. Colchicine decreases recurrences.
