A Long-Term, Multicenter, Double-Blind Study of an Escherichia Coli Extract (OM-89) in Female Patients with Recurrent Urinary Tract Infections

OM-89 significantly reduced the incidence of UTI during the 12 months of the study including 3 months of treatment and three 10-day booster courses. These results confirm that OM-89 is a valuable component of the management of recurrent UTI.
