Final answer:
The recommended prophylaxis for Acute Rheumatic Fever (ARF) is Penicillin G benzathine (A), with dosing intervals varying based on reinfection risk. Erythromycin may serve as an alternative for individuals with penicillin allergies.
Step-by-step explanation:
The recommended prophylaxis for Acute Rheumatic Fever (ARF) is indeed Penicillin G benzathine (A). According to the American Heart Association, a treatment regimen consisting of benzathine benzylpenicillin every 3 or 4 weeks is advised, depending on the patient's risk for reinfection. This is particularly important for preventing recurrent Streptococcus infections, which can lead to ARF. For those allergic to penicillin, alternatives such as erythromycin can be used. It's important to note that patients with severe penicillin allergies may need to consult with a specialist to determine the best prophylactic antibiotic for their specific situation.
