Hi, Consult with a nutritionist to establish a rigid salt-restricted diet (1.5 g sodium/d). And good that you have cut out salt, chocolate, caffeine. Meclizine is just one vestibulosupressant and if not responding you can try many other more competent like dimenhydrate, betahistidines, scopolamine, promethazine, diazepam, alprazolam, droperidol metoclopromide etc. They all are vestibulo suppressants and any single one of them can be used after consulting with your soctor. Doxylamine hydrochloride is first generation antihistamine but it is not that prolonged. It is used though in concomitant to some other vestibulosuppressants. You will need steroids and diuretics (thiazide, triamterene and acetazolamide etc.) and ephedrines too for the medical management of the disease. I am sure it will respond to it as most of the acute symptoms do. If the problem persist seek your doctor opinion to rule out meniere s syndrome in which there is an underlying cause to this meniere s disease that is thyroid disease etc. I suggets you should use Meniett device as its results have been fruitful and promising. Lets hope it gets fixed uptill here otherwise a step up would be required in guise of surgical interventions like Endolymphatic sac decompression or shunt placement Vestibular nerve section Labyrinthectomy Intratympanic injection of medications such as gentamicin or steroids. Seek an otorhinolaryngologist and stay in touch with them. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Ivan R. Rommstein, General Surgeon
