Oral penicillin V is typically prescribed for streptococcal pharyngitis for how many days?

For streptococcal pharyngitis, a full ten-day course of oral penicillin V is recommended to reliably eradicate Group A Streptococcus and minimize the risk of rheumatic fever. Penicillin V works best when levels are sustained for the entire treatment period, so shorter courses have been associated with higher rates of persistent infection or relapse. Therefore, ten days is the standard duration. Longer (fourteen days) isn’t needed and can worsen adherence, while shorter durations (five or seven days) are not standard because they’re less likely to ensure complete eradication.
