Very few antibiotic will help with urinary tract infection caused by certain strains of e.coli. Non will help with ESBL strain of this bacteria. Overuse of antibiotics is main cause of development of suberbugs such as MRSA or ESBL that are resistant to any known antibiotic.
Recommended alternative solutions such as cranberry products, or d-mannose will help just to the certain point with very week infections of 10000 or less bacterias per ml.
Two natural products that actually have significant impact on strong UTI caused by e.coli are Croatian E-kapi, and Canadian product called E-Drops Nano. Both contain extract from juniperus communis with mixture of other herbs that have very strong antibacterial properties. I had opportunity to practice in North America and Europe, and I did witness both product eliminating infections where multiply antibiotics failed !
