Once SBP develops, patients have a 70% chance of redeveloping the condition within 1 year. Prophylactic antibiotic therapy can reduce the recurrence rate of SBP to 20%. Some of the regimens used in the prophylaxis of SBP include norfloxacin at 400 mg orally every day [16] and trimethoprim-sulfamethoxazole at 1 double-strength tablet 5 days per week. [17]
