Ear Tone is a supplement claimed to help tinnitus. Does it work?
“Why do you bother blogging?” asked a colleague. “You take hours of your personal time to write, and you do it for free. You’re not even getting any citations for all that work.” I admit I found the questions a bit surprising. True, you won’t find SBM posts abstracted in PubMed. But I’m writing for an entirely different audience. I blog for the same reason that I became a pharmacist: to help people use medicines more effectively. Practicing as a pharmacist is one way to do that. In that setting, you’re helping one patient at a time. And seeing how your advice and support can enhance someone’s care is tremendously gratifying.
I see blogging as another form of pharmacy practice, hopefully with similar effects. Yes I do get regular hate mail, and the occasional legal threat, but there’s also gratitude for a post that resonated with someone, or helped them make better decisions about their health. When Google searches don’t give answers, I get questions — too many to answer. Today’s post is based on a request for help from someone seeking advice on natural supplements to treat ringing in their ears. They have tinnitus, and they’re frustrated at the limits of what their physician (and medicine) can do. They sent me an advertisement for a supplement called Ear Tone, a natural health product which is advertised (and approved) to provide tinnitus relief. Can natural supplements do what conventional medicine cannot? (more…)
There are several features of a symptom or illness that make it a convenient target for proponents of unconventional therapies. Subjective symptoms are more likely to be targeted than objective conditions – you don’t see many so-called “alternative” birth control treatments. Symptoms for which placebo effects alone are likely to produce the illusion of effectiveness are good targets for ineffective treatments. Symptoms that vary naturally over time also are good targets – patients are likely to seek treatment when their symptoms are maximal, which means spontaneous regression to the mean will provide an effective illusion of efficacy for any intervention. Illnesses with a substantial psychological component (such as those that are worsened by emotional stress or that are emotional, such as anxiety) are likely to benefit from non-specific effects of the therapeutic interaction, rendering the treatment itself irrelevant.
Finally, any condition or symptom for which there is currently no effective treatment provides a market ripe for exploitation.
Tinnitus has many of these features. Tinnitus describes the subjective experience of spontaneous noise perceived in one or both ears, which can be a buzzing, hiss, tone, or ringing sound. The severity of the tinnitus, its loudness, can vary over time, but perhaps more importantly the degree to which the tinnitus is bothersome can vary considerably. The sound is distracting and can have a significant impact on quality of life. Those with tinnitus can ignore the sound at times (depending on its severity), can be distracted from the sound, and may even learn through cognitive therapy to become accustomed to it. Therefore we might expect that tinnitus is amenable to placebo effects.
Finally, there is no proven effective treatment for tinnitus, which means that those who suffer from tinnitus may be desperate for a treatment. Desperation is a commodity highly prized by snake-oil salesmen.
