英语翻译要寄往美国,药品商品名 波立维,海关要求在报关单上写明该药品为患者自用药,需长期服用.请问：该药品为患者自用药,

This medicine is for the patient himself/herself over a long period.
提醒一下：
美国海关对药品规定有两项：处方药(prescription drug)和非处方药(non-presciption drug).如果是处方药,则必须出示由医生出具的处方（prescription）,否则会有麻烦.
如果是非处方药,译文如下：
This non-prescription drug is only for the patient himself/herself over a long period of time.
如果是处方药,译文如下：
This prescription drug is prescribed by a qualified doctor and is only for the patient himself/herself over a long period of time.
(该处方药系合格医生开具,由病人（男/女）自用,并且长期服用).
