Urinary tract infections (UTIs) are the most common bacterial infections in women, with about 50% of women experiencing at least one UTI in their lifetime.

The main pharmacological treatments of cystitis usually involve the use of antibiotics, in particular quinolones (such as ciprofloxacin and levofloxacin), fosfomycin, second-generation and third-generation cephalosporins, and b-lactam antibiotics associated with b-lactamase inhibitors.

This is a double-blinded, randomized, placebo-controlled, parallel-group study evaluating the effect of the probiotic on recurrent urinary tract infection (UTI) in adult women recently treated for UTI.

Primary objective The primary objective is to evaluate the effect of oral supplementation with probiotic on the frequency of UTI during six months from start of intervention in adult women with recurrent UTI.

1. Willing and able to give informed consent for participation in the study.
2. Woman aged 18-50 years old at screening.

4. Currently on antibiotic treatment for UTI, at the time of screening. Antibiotic treatment must stop within three days prior to first IP dose.
5. Recurrent UTI defined as at least two UTIs during the last six months or at least three UTIs during the last 12 months, according to information given by the subject.
6. Able and willing to comply with the restrictions defined for the the study period (see Section 10.6).
7. Access to Bank ID and ability to use the e-health platform (i.e. Internet access).
8. Ability to understand and comply with the requirements of the study, as judged by the Investigator.

Exclusion Criteria:

1. Postmenopausal (defined as 12 months of amenorrhoea).

2. Pregnant or breastfeeding.

4. Irregular menstruations combined with perimenopausal symptoms.

5. Known hypersensitivity or allergy to any of the components of the test product, or to the comparator (placebo).

6. Use of spermicide contraceptives including spermicidal condom within three days prior to first IP dose.

In this study, the IP is a food supplement and not an investigational medicinal product.

However, the procedures for monitoring, collecting and reporting of AEs will be the same as for an investigational medicinal product.
