Patients who experience dizziness after taking the drug may be caused by side effects or adverse reactions to the drug. Patients are advised to read the instructions carefully and observe whether there are any central nervous system side effects. During this period, patients should drink more water to accelerate the metabolism of the drug in the body. If the degree of dizziness does not decrease, but increases, patients need to consult a hospital for examination and treatment. 1. If there are no central adverse reactions to the drug, and patients also show symptoms of dizziness, it may be caused by the disease itself. If the degree of dizziness is heavy with problems such as rotation of vision or unstable walking, it is important to consult a hospital for timely examination, because this condition may be caused by posterior circulation ischemia or Ménière’s disease.
