What is the typical duration of antibiotics for acute bacterial prostatitis?

• A. 4-6 weeks
• B. 3-5 days
• C. 2-3 months
• D. 1 year

Answer: (A)

In acute bacterial prostatitis, the aim is to clear infection from prostatic tissue, which takes time because the prostate doesn’t drain and has relatively slow drug penetration. Because bacteria can persist within prostatic ducts and tissue, a prolonged course is needed to ensure complete eradication and symptom resolution. Short courses of antibiotics won’t adequately sterilize the gland and increase the risk of relapse or progression to a longer-standing prostatitis. Therefore, a four- to six-week antibiotic course is standard, using agents with good prostatic penetration (such as fluoroquinolones or trimethoprim-sulfamethoxazole). Severely ill patients may start with IV therapy, but the total duration still typically falls within this several-week range.
