The time to stop taking Flunarizine is not clear, and patients are advised to follow the doctor’s instructions for medication. Flunarizine is a calcium channel blocker, commonly used in the treatment of cerebral hypoperfusion, vertebral artery ischemia, adjuvant treatment of epilepsy and prevention of migraines, but also able to alleviate tinnitus, cerebral dizziness symptoms. There is no clear standard for the withdrawal time after taking Flunarizine, and it needs to be combined with the patient’s condition and other comprehensive judgment. Some patients taking Flunarizine may experience drowsiness, fatigue, insomnia, burning sensation in the stomach and other adverse reactions. Flunarizine is contraindicated if the patient is allergic to the components of the drug or has a previous history of depression or acute cerebral hemorrhagic disease. If the patient’s fatigue symptoms gradually worsened after using the drug, the dosage needs to be reduced or discontinued as prescribed by the doctor. It is recommended that patients use Flunarizine under the guidance of a physician, and should not use the drug indiscriminately or increase or decrease the dosage of the drug on their own. Flunarizine should be used with caution by drivers, machine operators, and people with extrapyramidal disorders such as Parkinson’s disease to prevent accidents.
