flowerysuec,
Thanks for the question.
Recurrent/persistent pericarditis can be difficult to treat. The most appropriate therapy is not definitively known, in part because the condition is not common.
The first item of business is to secure the diagnosis of pericarditis. Make sure that you feel comfortable with the manner in which the diagnosis was made -- by a cardiologist?, was an echo done?, was an EKG done? etc.
I've included a paragraph from the June 2 1998 Circulation journal. The summary statement is that colchicine is the drug associated with the most success in treating long-term pericarditis.
"Fifty-one affected patients (36 men and 15 women; mean +/- SD age, 40.8 +/- 18.7 years) who were treated with colchicine to prevent further relapses were followed up for <or=to 10 years (range, 6 to 128 months; mean, 36.0 months). The pericarditis was idiopathic in 33 patients and secondary in 18. Despite treatment with NSAIDs (n=47), corticosteroids (n=29), pericardiocentesis (n=8), or some combination thereof, 187 recurrences (mean, 3.58 +/- 3.64; range, 2 to 15) were noted before colchicine therapy was initiated, with a mean interval between crises of 2.0 months (range, 0.5 to 19 months). During 1004 patient-months of colchicine treatment, only 7 of 51 patients (13.7%) presented with new recurrences. Colchicine was discontinued in 39 patients, and 14 of them (35.8%) experienced relapses. These recurrences were generally minor and were effectively controlled in all patients by the reinstitution of colchicine therapy, sometimes with a dose adjustment of the drug (<or=to2 mg/d). Gastrointestinal side effects were mild (diarrhea and nausea) and resolved in all patients. During the 2333 patient-months of follow-up, 31 patients (60.7%) remained recurrence-free. Comparison of the symptom-free periods before and after colchicine treatment yielded significant statistical differences (3.1 +/- 3.3 versus 43.0 +/- 35.0 months, P<0.0001). The authors concluded that colchicine was effective and safe for the long-term prevention of recurrent pericarditis."
Our experience at the CCF is to start treatment with 0.5 mg po bid of colchicine.
Talk to your doctor. Colchicine may or may not be right for you depending on your medical history.
Good luck.
