Hi Baskar, Thanks for writing in. I am a qualified and certified cardiologist. I read your mail with diligence. There is data from CMC Vellore of stopping penicillin at age 30 with no recurrence. But my worry is reports from AIIMS.
If you are taking injection for last 25 years that means you would be above 40 years of age. From India, there is excellent data available from CMC Vellore where they have discontinued the injections (personally I discontinue at age 50), the only catch is there are some anecdotal case reports of stopping penicillin and rheumatic fever
recurrence between age 40-50. Some from Institute of repute like All India Institute of Medical Sciences New Delhi. In last 50 years no report I have come across of RF recurrence beyond age 50. There are reports of 65 year old man from the US during second world war. So, my suggestion would be to go until age 50. Substitutes to inject-able penicillin have recurrence rate which would be comparable to stopping the drug seems better option that is my view and I have studied and seen more rheumatic fever /rheumatic heart disease
patients from all over the world than any other alive cardiologist. Regards.
With Best Wishes
