From the FDA Drug Label
- 8 Chronic Bacterial Prostatitis Levofloxacin tablets are indicated for the treatment of chronic bacterial prostatitis due to Escherichia coli, Enterococcus faecalis, or methicillin-susceptible Staphylococcus epidermidis [see Clinical Studies (14.6)].
The best antibiotic for prostatitis with a doxy allergy is levofloxacin.
- Key points:
- Indicated for chronic bacterial prostatitis
- Effective against Escherichia coli, Enterococcus faecalis, and methicillin-susceptible Staphylococcus epidermidis 1
From the Research
For prostatitis in patients with a doxycycline allergy, levofloxacin 500mg once daily for 2-4 weeks is the best alternative antibiotic, as it has been shown to be effective in treating chronic bacterial prostatitis and has a favorable pharmacokinetic profile, allowing it to penetrate prostate tissue well 2.
Key Considerations
- The choice of antibiotic depends on the type of prostatitis (bacterial vs. non-bacterial), culture results if available, and the severity of symptoms.
- Fluoroquinolones, such as levofloxacin and ciprofloxacin, are effective in treating chronic bacterial prostatitis due to their ability to penetrate prostate tissue and reach therapeutic concentrations 3, 4.
- Trimethoprim-sulfamethoxazole (TMP-SMX) 160/800mg twice daily for 2-4 weeks can be used as an alternative for patients who cannot take fluoroquinolones, as it also penetrates prostate tissue well.
- In cases of severe allergies to multiple antibiotics, fosfomycin 3g every 72 hours for 2-3 weeks might be considered.
Treatment Duration and Management
- Patients should complete the full course of antibiotics even if symptoms improve earlier.
- Staying well-hydrated and avoiding alcohol, caffeine, and spicy foods during treatment can help manage symptoms.
- The treatment of chronic bacterial prostatitis requires a prolonged course of antibiotics, typically 2-4 weeks, to ensure effective eradication of the infection 5, 2.
Monitoring and Follow-up
- Patients should be monitored for clinical response and microbiological eradication after treatment.
- A significant decrease in prostate-specific antigen (PSA) levels has been observed in patients with chronic bacterial prostatitis after treatment with levofloxacin or ciprofloxacin, suggesting a potential association between bacterial persistence and PSA levels 6.
