Lipo-Flavonoid for ringing in ears

Unfortunately, the pharmaceuticals learn off of us when a drug does not work with all of it's side effects including the tinnitus, vertigo and other vestibular manifestations like you exhibited. One reason they took it off of the market for bad marketing, too many side effects and outcomes of the drug use and perhaps evidence of poor trials before allowing it to be used before giving out to the public.
Money is always involved along with competition among the big pharmaceutical companies. The FDA has some say in who can put any drug out on the market and when, so if there is any iffy on any medicine, they may say NO but sometimes pressure is put on to allow a temporary trial for use to see if it may work. We don't always know if this is going on behind the scenes except for when the drug/medicine is prescribed to us and we use it. When the reporting comes in of severe side effects from physicians and reporting to SIDE EFFECTS of pharmaceutical websites come crashing in - then the drug is pulled off of the market and is no longer available to the public. Further investigation is done on that particular drug to see why it caused the side effects by the FDA. Records are kept of deaths, and disabilities and the like by the CDC, FDA and other government organizations. We are not privy to those records. BUT we suffer the consequences of their mistakes. Especially when they do not consider that most of the drugs/medicines on the market today cause tinnitus/vertigo/ hearing loss/vestibular injury of some kind/ and other brain injuries. Just look in any drug book and check out any medicine's side effect. Where the drug comes from also tells you if it is pure or if it has heavy metals added to it or other unnecessary ingredients to 'make it work' better for you. [or to kill you] Always question first, what is the medicine - class of drug - what will it do for me - for how long - will it interact with my other drugs/medicines that I take right now, including the OTCs - what are the side effects - and will it make my current symptoms worse? These are good questions for your pharmacist to answer since the prescribing MD will not understand who to answer these questions. Always trust your pharmacist .... I do because he knows me and defends me from actions taken by my many specialists.
