Patients still feel dizzy a few days after motion sickness. If the degree of dizziness is similar to the reaction at the time of motion sickness, consider that the patient has not fully recovered and can improve the symptoms of dizziness by taking oral vestibular inhibitors. Patients can take betahistine mesylate orally, two tablets once, three times a day, and observe the changes of their condition. Patients are also advised to take oral medications to improve blood circulation, such as ginkgo biloba ketone ester drops and hemosiderin tablets, which may have a mitigating effect on the motion sickness reaction after motion sickness. During this period, patients must ensure sufficient sleep and pay more attention to rest, which will help to relieve dizziness. If the dizziness is more severe after a few days of motion sickness, accompanied by nausea and other symptoms, it is considered to be caused by vasospasm or posterior circulation ischemia, and the patient should consult a hospital for transcranial Doppler, cervical vascular ultrasound and other examinations to clarify. If it is a problem in these areas, it is suggested that the patient should be sedated with blood-stasis activating drugs to improve the symptoms, such as vincristine, blood sparing or thrombosis.
