Which antibiotic is used to treat Rheumatic Fever infection?

The treatment of Rheumatic Fever, which is a complication that can arise from untreated streptococcal throat infections, specifically utilizes Penicillin G benzathine as a first-line antibiotic. This choice is based on Penicillin's effectiveness against the bacteria responsible for the initial infection, Streptococcus pyogenes (Group A Streptococcus).

Penicillin G benzathine is administered as a long-acting intramuscular injection, allowing it to provide prolonged antibacterial effects, which is particularly beneficial in preventing further streptococcal infections that could exacerbate rheumatic heart disease or lead to other complications. This antibiotic is especially chosen for Rheumatic Fever because it not only treats the infection but also facilitates long-term prophylaxis against future episodes.

In contrast, while Amoxicillin is effective against many infections, it is not the first choice for Rheumatic Fever due to the need for a longer-acting formulation. Ceftriaxone is a broad-spectrum cephalosporin antibiotic and, although it can treat various infections, it is not specifically recommended for Rheumatic Fever. Clindamycin can be an alternative in penicillin-allergic patients with certain infections but is not the preferred option for treating this condition. Thus, Penicillin G benz
