毒理性
◉ 母乳喂养期间使用概述:由于甲基多巴在母乳中的含量较低,婴儿摄入的量很小,预计不会对哺乳婴儿造成任何不良影响。不需要采取特殊预防措施。
◉ 对哺乳婴儿的影响:在对15名年龄从不到1周到8周的婴儿进行研究时,他们的母亲每天服用0.25至1.5克的口服甲基多巴,没有报告出现急性或长期不良影响。
◉ 对泌乳和母乳的影响:甲基多巴可以增加血清催乳素水平并导致乳汁分泌过多。在已建立泌乳的母亲中,其催乳素水平可能不会影响她的哺乳能力。
◉ Summary of Use during Lactation:Because of the low levels of methyldopa in breastmilk, amounts ingested by the infant are small and would not be expected to cause any adverse effects in breastfed infants. No special precautions are required.
◉ Effects in Breastfed Infants:No acute or long-term adverse effects were reported in any 15 infants ranging in age from less than 1 week to 8 weeks of age whose mothers were taking oral methyldopa 0.25 to 1.5 grams daily.
◉ Effects on Lactation and Breastmilk:Methyldopa can increase serum prolactin and has caused galactorrhea. The maternal prolactin level in a mother with established lactation may not affect her ability to breastfeed.
