It all depends on whether he can swallow vitamins or not. We have 4 kids and none of them have ever had any drugs of any kind, including antibiotics. We do things differently. I'm 37 and never have had any antibiotics, etc. That being said, here's what I do for a UTI in kids your son's age:
7 droppers (not just drops) of Herbs for Kids Echinacea/Astragulus for 5 days
1 PB8 (open the capsule and dump the contents into the mouth or mix it in something) until his bowels start to get loose
50,000iu of vitamin A for 4 days (it's not toxic at these therapeutic levels for short term, but it WILL wipe out ANYTHING)
For kids/adults that can swallow:
Goldenseal instead of the Echinacea/Astragulus
same on the PB8 and vitamin A (more for adults)
If you have any questions....feel free to message me.
LOL "Real Doctors" may also do more than just prescribe meds as instructed by their pharmaceutical reps....they might actually know a little herbology or decide that wiping out ALL bacteria - good and bad - might not be the best idea with our Western diets.
PS: A fever is a GOOD thing. It is his body letting you know that it's doing it's job by fighting it. If my kids get one and I let it ride. It's over 3x faster than the kids whose parents felt like they needed to medicate. Meds only bring the fever down 1-2 degrees - right back into the range that the bacteria grows perfectly - turning their kids into a petri dish. At 105.5 we'll bring it down with cool cloths and getting them adjusted. Only one has ever gotten that high and it was over in 40 hours.
