Since your symptoms have only partially improved after a week of Stablanz-PV and Fourts B, the best next step is to consult your prescribing doctor or an ENT specialist for a detailed evaluation of your inner ear. They can determine if your treatment needs adjusting. In the meantime, please avoid sudden movements, stay well-hydrated, and sit or lie down immediately if you feel unsteady to prevent falls. Your safety and comfort are the top priorities, and a specialist can help get you back on track.
