From the Guidelines

The initial approach to prostatitis should prioritize determining the specific type, as treatment varies accordingly, with a focus on symptom management and supportive care due to the lack of clear evidence on treatment duration. For acute bacterial prostatitis, fluoroquinolones like ciprofloxacin (500mg twice daily) or levofloxacin (500mg once daily) are typically prescribed, although the optimal duration of treatment is unknown 1. Trimethoprim-sulfamethoxazole (160/800mg twice daily) is an alternative option. Patients with severe symptoms may require hospitalization for intravenous antibiotics.

Key Considerations

  • Determining the type of prostatitis is crucial for guiding treatment
  • Symptom management and supportive care are essential due to the lack of clear evidence on treatment duration
  • Fluoroquinolones and trimethoprim-sulfamethoxazole are commonly used antibiotics for bacterial prostatitis
  • Chronic pelvic pain syndrome (non-bacterial prostatitis) may require a multimodal approach including alpha-blockers, anti-inflammatory medications, and potentially muscle relaxants
  • Supportive measures for all types include adequate hydration, warm sitz baths, avoiding irritants, and regular ejaculation to help drain prostatic fluid

Treatment Approach

  • Acute bacterial prostatitis: fluoroquinolones or trimethoprim-sulfamethoxazole for an unknown optimal duration 1
  • Chronic bacterial prostatitis: a longer course of antibiotics (4-12 weeks) may be necessary, although the optimal duration is unknown 1
  • Chronic pelvic pain syndrome (non-bacterial prostatitis): multimodal approach including alpha-blockers, anti-inflammatory medications, and potentially muscle relaxants

Important Considerations

  • Pain management is important, particularly for chronic forms
  • Treatment effectiveness varies based on the type of prostatitis, with bacterial forms responding better to antibiotics while chronic non-bacterial forms often require ongoing symptom management and may benefit from pelvic floor physical therapy
  • The lack of clear evidence on treatment duration highlights the need for individualized care and close monitoring of patients with prostatitis 1

From the FDA Drug Label

The usual duration is 7 to 14 days; however, for severe and complicated infections more prolonged therapy may be required.

ADULT DOSAGE GUIDELINES Infection Severity Dose Frequency Usual Durations

  • used in conjunction with metronidazole ** Drug administration should begin as soon as possible after suspected or confirmed exposure Chronic Bacterial Prostatitis Mild/Moderate 500 mg q 12 h 28 Days

The initial approach and treatment for Chronic Bacterial Prostatitis is ciprofloxacin 500 mg administered orally every 12 hours for 28 days 2.

From the Research

Initial Approach to Prostatitis

The initial approach to prostatitis involves a thorough medical history and physical examination, including abdominal, genital, and digital rectal examination to assess for a tender, enlarged, or boggy prostate 3.

Diagnosis of Prostatitis

Diagnosis is predominantly made based on history and physical examination, but may be aided by urinalysis and urine cultures to determine the responsible bacteria and its antibiotic sensitivity pattern 3.

Treatment of Acute Bacterial Prostatitis

Treatment for acute bacterial prostatitis typically involves oral antibiotics and supportive measures, with hospitalization and broad-spectrum intravenous antibiotics considered in patients who are systemically ill or have risk factors for antibiotic resistance 3.

  • Typical antibiotic regimens include:
    • Ceftriaxone and doxycycline
    • Ciprofloxacin
    • Piperacillin/tazobactam

Treatment of Chronic Bacterial Prostatitis

For chronic bacterial prostatitis, treatment options include:

  • Ciprofloxacin, which has been shown to be beneficial in the treatment of chronic bacterial prostatitis, particularly in cases of Escherichia coli prostatitis 4
  • Trimethoprim-sulfamethoxazole, which has been used to treat chronic bacterial prostatitis due to gram-negative organisms, with varying degrees of success 5, 6
  • A therapeutic trial of antibiotics, even when patients do not appear to have bacterial prostatitis, as the rate of occult infection is high 7

Additional Considerations

Additional laboratory studies and radiography may be obtained based on risk factors and severity of illness, but are not typically necessary for the diagnosis and treatment of prostatitis 3.
