Q

How long do you continue prophylactic antibiotics for after an episode of acute rheumatic fever?

A

trick question

this used to be 10 years or to age 21, whichever was longer.

However now it depends on specific patient characteristics which can lead to a course as short at 12 months or up to 40 years old.

For mild RHD the old rule applies, but even then they patient needs to meet criteria such as no further episodes of ARF to then consider ceasing prophylaxis.

In any case, a cardiology follow up with echo is necessary.
