if there is no carditis during initial attack of RH fever, you can stop giving prophylaxis at 21yrs of age.

if there was carditis without any residual valve damage, prophylaxis can be stopped at 10yrs after the episode.

if there was carditis with residual valve damage, the prophylaxis must be continued till 40yrs age or at 10yrs after the last episode.
