What is the primary goal of administering prophylactic Benzathine PCN in patients who had Rheumatic fever?

The primary goal of administering prophylactic Benzathine penicillin (PCN) in patients with a history of rheumatic fever is to prevent the recurrence of rheumatic fever itself. Benzathine penicillin works by providing long-term protection against streptococcal infections, which are the precipitating cause of rheumatic fever. Recurrent episodes can lead to more severe cardiac complications, including rheumatic heart disease, so preventing recurrences is vital for safeguarding the patient's heart health.

The strategy involves regular administration of the antibiotic to ensure that even if the patient is exposed to streptococci, the infection can be quickly managed, thereby reducing the risk of triggering another rheumatic fever episode. This prevention is particularly crucial given that the ramifications of recurrent rheumatic fever can have lasting impacts on the cardiovascular system. Thus, the focus of the prophylactic treatment is to maintain the patient's health by avoiding any future situations that could lead to another episode of rheumatic fever.
