@Juan -- I tried it as well, what appeared to be a high quality extract. Made my tinnitus worse--consistently.
I have tried a couple of medications, supplements etc and really nothing helps a lot. My guess is many of us take the drugs just to think we did all that was in our hands in order not to worsen our H, T or our hearing.
The only two meds that did something, although very minor impact were paroxetine (very low dose), and deflazacort after a very loud noise exposure (and this has to be taken when there is still a lot of pressure, tension etc inside the ears, as soon as possible). When the pain, pressure, etc start to subside it is too late for deflazacort.
Prednisone did not work at all, did nothing.
Vitamins and supplements.. most of them did nothing.
A couple of my friends are doctors and they dont really know what to advise. From their viewpoint, anti-inflammatories, anti deppresants, SSRIs and all that.. they either work or dont work. Apparently they work for some people and not for others and it all comes down to a matter of trial and error, as un-scientific as that. Keep trying till you find the right medication.
