Doubt it....good evening...I m Dr. Dariush Saghafi and I m a neurologist in the Cleveland, OH area of the world....are you familiar with that area of the globe? I ve got to be honest that as a neurologist I pretty much have found meclizine to be of very little benefit to my patients as a whole. There are some patients who get some benefit from the drug. But by and large, most people do not really have their dizziness or vertigo addressed very adequately using this medication. Cervical spondylosis is always somehow made the culprit in vertigo but in fact, what you ve described as changes in posture AND HEAD POSITION is controversially related to or caused by degenerative joint or disc disease. Bottom line is that cervical spondylosis causing TRUE VERTIGO ONLY is highly controversial while DIZZINESS taken to be a syndrome consisting of neck pain, dizziness (combination between lightheadedness and vertigo) and possible headache along with imbalance is considered more appropriate terminology. You may also address specific questions to me by perusing: http://doctor.healthcaremagic.com/doctors/dr-dariush-saghafi/68474 or looking me up by name (DARIUSH SAGHFI, MD- Cleveland, Ohio, USA on this network) Alternatively, if you would like to try a real time webcam consult you can find me doing consults either by webcam, texting, or by audio at: You can find me on this network on Wed-Sat, 3a-6a (New York City Time) as well as Sunday 11p-3a. Other days and times are possible but we d need to make an appointment. And I almost forgot....if this response provided you with some good information...could you please give the answer a STAR RATING....it gets me a bigger bag of potato chips to munch on while I m answering questions! I kid you not...tonight I m doing a 7 oz. bag....last night I think I was only getting 3 oz. bags! LOL! Cheers.
