Penicillin V is widely used as an antibiotic to treat various bacterial infections, particularly those caused by gram-positive organisms. It is effective in treating streptococcal infections such as strep throat and mild to moderate respiratory tract infections. Due to its acid stability, Penicillin V can be administered orally, making it a convenient option for outpatient treatment. It is also used in patients with a history of rheumatic fever as a prophylactic agent to prevent recurrent streptococcal infections. Penicillin V is not effective against beta-lactamase-producing bacteria and is generally not used for severe or systemic infections. Its use is limited to mild infections where oral therapy is appropriate and the likely pathogens are sensitive to penicillin.
