Preventive treatment is designed to decrease headache frequency. It should be used if headaches are too frequent, disabling, or associated with worrisome neurological features or if acute treatment is overused or ineffective. The chosen drug should be given an adequate trial in the absence of interfering medications. Choose a drug based on its efficacy, adverse event profile, and the presence of coexistent conditions.
预防性治疗旨在降低头痛发作频率。如果头痛发作过于频繁、导致功能障碍、伴有令人担忧的神经学特征，或者急性治疗用药过度或无效，则应采用预防性治疗。在没有干扰药物的情况下，应对所选药物进行充分的试验。根据药物疗效、不良事件情况以及并存疾病来选择药物。
