Treatment for Prostatitis
The treatment for prostatitis depends on the specific type, with fluoroquinolones such as levofloxacin 500 mg once daily or ciprofloxacin 500 mg twice daily for 2-4 weeks being the first-line therapy for bacterial prostatitis, achieving success rates of 75-92%. 1, 2, 3
Types of Prostatitis and Initial Management
Acute Bacterial Prostatitis
- Initial antibiotic therapy:
- For severe cases: Parenteral antibiotics 1
- Piperacillin-tazobactam 2.5-4.5 g three times daily
- Ceftriaxone 1-2 g once daily
- Cefotaxime 2 g three times daily
- IV fluoroquinolones (ciprofloxacin 400 mg twice daily or levofloxacin 750 mg once daily)
- For less severe cases: Oral fluoroquinolones 3
- Ciprofloxacin 500 mg twice daily
- Levofloxacin 500 mg once daily
- For severe cases: Parenteral antibiotics 1
- Duration: 2-4 weeks 1, 3
- Success rate: 92-97% 1, 3
Chronic Bacterial Prostatitis
- First-line therapy: 1, 2, 4
- Levofloxacin 500 mg once daily for 4-12 weeks
- Ciprofloxacin 500 mg twice daily for 4-12 weeks
- Alternative options: 1
- Doxycycline 100 mg twice daily for 2-4 weeks
- Success rate: 75-76.8% 2, 4
Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS)
- First-line therapy for urinary symptoms: 3
- Alpha-blockers (tamsulosin, alfuzosin, doxazosin, or terazosin)
- Additional therapies: 1, 3
- Non-narcotic analgesics
- Amitriptyline or cimetidine
- Stress management techniques
- Pelvic floor muscle relaxation
Diagnostic Approach
Clinical evaluation:
- Assess for pelvic pain, urinary symptoms (frequency, urgency, dysuria)
- Digital rectal examination to check for tender, enlarged, or boggy prostate 5
Laboratory testing:
Avoid vigorous prostate massage in acute bacterial prostatitis 1
Consider imaging (CT scan or excretory urography) if fever persists after 72 hours of treatment 1
Treatment Monitoring and Adjustment
Adjust antibiotics based on culture and antibiogram results (needed in approximately 76.6% of cases) 1
Clinical reassessment after 2 weeks to evaluate symptom improvement 1
Follow-up urine culture at the end of treatment to confirm eradication 1
PSA measurement 3 months after resolution if elevated during infection 1
Use symptom indices (NIH-CPSI or IPSS) to quantify symptoms and monitor response 1, 3
Common Pitfalls and Caveats
Antibiotic resistance: Fluoroquinolone resistance is increasing; consider local resistance patterns when selecting antibiotics 1
Recurrence: Approximately 10% of acute bacterial prostatitis cases evolve into chronic bacterial prostatitis 1
Complications: Early and adequate treatment is crucial to prevent complications such as prostatic abscesses, sepsis, or progression to chronic prostatitis 1
Atypical pathogens: For Chlamydia trachomatis, use azithromycin 1.0-1.5 g single dose or doxycycline 100 mg twice daily for 7 days; for Mycoplasma genitalium, use azithromycin 500 mg on day 1, then 250 mg for 4 days 1
Antimicrobial prophylaxis: Strongly recommended for all patients undergoing transrectal prostate biopsy to prevent acute bacterial prostatitis 1
By following this treatment algorithm and monitoring protocol, most patients with prostatitis can achieve significant symptom improvement and, in cases of bacterial prostatitis, eradication of the causative organism.
