Cipro, scientifically known as flunarizine hydrochloride, is a very common prescription drug. The efficacy of Cipro in the prevention and treatment of headaches and dizziness is still worthy of recognition. The price of Cipro is generally not expensive and is acceptable to the average person. The dosage is not quite the same for different ages and conditions, but some patients have reported that Cipro is relatively resistant to treatment, and if they stop taking Cipro, the original pain or dizziness will appear and the condition will recur. Therefore, it is mainly used for the prophylactic treatment of typical or atypical migraine and symptomatic treatment of vertigo caused by vestibular dysfunction. Adverse effects include drowsiness and fatigue, weight gain, and occasional depression with long-term use, which is particularly likely to occur in female patients. Extrapyramidal symptoms are likely to occur in the elderly and may recover after discontinuation of the drug. Rare adverse reactions include heartburn, nausea, stomach pain, insomnia, anxiety, dry mouth, muscle pain, and skin rash. Contraindications: It should be contraindicated in patients with depressive tendencies or in patients with Parkinson’s disease and other extrapyramidal disorders. Precautions: Treatment should be discontinued if fatigue gradually increases during treatment or if the efficacy of the treatment decreases during maintenance, and should not be taken for a long period of time. Also, pay attention to the scope of drug use while driving a vehicle or operating a machine. Be careful to discontinue medication after having extrapyramidal symptoms. When combined with alcohol and hypnotic or sedative drugs, excessive sedation of the central nervous system can be seen, and care should be taken to prevent this.
