  • This medication comes in tablet form. It is usually taken by mouth once or twice a day.

  • For the medication to work properly, it must be taken as directed.

Antivert Dosing Information

The dose of Antivert your healthcare provider recommends will vary, depending on a number of factors, including:
  • How you respond to Antivert
  • The medical condition being treated
  • Other medications you are taking
  • Other medical conditions you may have.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
