Medications
During MD episodes, medications to reduce nausea are used, as are drugs to reduce the anxiety caused by vertigo. For longer-term treatment to stop progression, the evidence base is weak for all treatments. Although a causal relation between allergy and Ménières disease is uncertain, medication to control allergies may be helpful. To assist with vertigo and balance problems, glycopyrrolate has been found to be a useful vestibular suppressant in patients with Menieres disease.Diuretics, such as the thiazide-like diuretic chlortalidone, are widely used to manage MD on the theory that it reduces fluid buildup (pressure) in the ear. Based on evidence from multiple but small clinical trials, diuretics appear to be useful for reducing the frequency of episodes of dizziness but do not seem to prevent hearing loss.In cases where hearing loss and continuing severe episodes of vertigo occur, a chemical labyrinthectomy, in which a medication such as gentamicin is injected into the middle ear and kills parts of the vestibular apparatus, may be prescribed. This treatment has the risk of worsening hearing loss. Diet
People with MD are often advised to reduce their sodium intake. Reducing salt intake, however, has not been well studied.Based on the assumption that MD is similar in nature to a migraine, some advise eliminating "migraine triggers" such as caffeine, but the evidence for this is weak. There is no high-quality evidence that changing diet by restricting salt, caffeine or alcohol improves symptoms.
Physical therapy
While use of physical therapy early after the onset of MD is probably not useful due to the fluctuating disease course, physical therapy to help retraining of the balance system appears to be useful to reduce both subjective and objective deficits in balance over the longer term. Counseling
The psychological distress caused by the vertigo and hearing loss may worsen the condition in some people. Counseling may be useful to manage the distress, as may education and relaxation techniques. Surgery
If symptoms do not improve with typical treatment, surgery may be considered. Surgery to decompress the endolymphatic sac is one option. A systematic review in 2015 found that three methods of decompression have been used – simple decompression, insertion of a shunt, and removal of the sac. It found some evidence that all three methods were useful for reducing dizziness, but that the level of evidence was low, as trials were not blinded nor were placebo controls used.Another 2015 review found that, on autopsy, shunts used in these surgeries often turn out to be displaced or misplaced, and recommended their use only in cases where the condition is uncontrolled and affecting both ears. A systematic review from 2014 found that in at least 75% of people, EL sac decompression was effective at controlling vertigo in the short term (>1 year of follow-up) and long term (>24 months).An estimated 30% of people with MD have Eustachian tube dysfunction.
