What over-the-counter meds are you referring to?
Also, your doctor is wrong about there not being a home remedy for a UTI, but they're not taught to suggest that; they're taught to treat. Cranberry juice or the capules didn't do a thing for me except raise my sugar level. The juice you need to drink the unsweetened variety, which I understand isn't really fit to drink as is. The pills may help some but they didn't help me. The only thing that has is D-Mannose (Clear Tract). Expensive but worth every penny. I would get a UTI every 2-3 months, sometimes more often. I've been using the D-Mannose since September and no problems since. Now, I did try stopping it not too long ago, just to see if I could, and I ended up with the beginnings of an infection starting. Took the D-Mannose for three days like it says and felt fine afterwards. Also, there's an old-wives tale about using baking soda to cure an infection, but it turned out to actually work, as this is what they used years and years ago before they even had meds to treat it. I even know someone who used this method and her UTI went away. If you catch it right away, you can usually clear it up on your own, but if you let it go until the bacteria has mulriplied and has a good foothold, then you may need antibiotics so it doesn't spread to the kidneys.
