If a patient suddenly develops vertigo with nausea, vomiting, or even tinnitus and hearing loss, and no specific head lesion is found after a CT or MRI of the head, it can be considered vertigo. The first and foremost treatment for vertigo is sedation, and patients can be given flunarizine hydrochloride capsules to take orally. If the patient vomits more obviously and struggles to take oral medication, metoclopramide or promethazine hydrochloride can be injected intramuscularly to relieve the vertigo. After that, the patient can be treated with drugs to improve circulation and nerve nutrition, more commonly used include ginkgolide injection, prostaglandin injection and methylcobalamin dispersible tablets, normally the patient’s vertigo symptoms will be significantly improved after 3-5 days of medication. During the onset of the disease, patients must not be allowed to move freely to avoid falling.
