Is it possible to use bladder medications Canephron and D-mannose for a period of 6 months without interruption?

According to the Summary of Product Characteristics, Canephron can be used for up to 4 weeks (for further use, a doctor should be consulted after three weeks). Canephron therapy can be repeated in patients who have not had a recurrence of urinary tract infections in the past within 3 months of the end of previous treatment. https://www.gdziepolek.pl/produkty/98626/canephron-tabletki/ulotka/246180 D-mannose is used in medicine primarily as a means of supporting the fight against urinary tract infections. The use of D-mannose is a relatively new therapeutic treatment. Due to the lack of broad observations proving the effectiveness and safety of therapy, the recommendations for the use of D-mannose remain cautious. To sum up, I encourage you to contact your doctor or family doctor who specialize in the treatment of urinary tract infections and have full documentation of your health.
