Biohistin 16 Tablet is used to prevent and cure Ménière's disease, an inner-ear illness. Biohistin 16 Tablet increases blood flow to the inner ear, lowering the pressure of extra fluid there. This pressure is hypothesized to cause symptoms of nausea, vertigo (dizziness), tinnitus (ringing in the ears), and hearing loss in persons with Ménière's illness. This medication lessens the severity of the symptoms and the frequency with which they occur. It will be more successful if you take this medication as advised, so try not to skip any doses. It may take a few weeks before you see any changes, but continue taking it even if you feel better until your doctor says it's safe to stop.
