谢谢你的信息.好像不少人吃了都引起便秘.其实我现在主要还是恶心,我觉得恶心比吐 还难受.准备试试楼上推荐的unisom sleep tab了.zofran先拿来做back up吧. 这是刚才在网上查到的关于zofran: Questions will come up about using ondansetron (zofran) for morning sickness . It was thought to be relatively safe … but now there are concerns. Ondansetron use in the first trimester is linked to a two-fold increase in the risk of congenital heart defects and cleft palate. Plus ondansetron prolongs the QT interval … and electrolyte disturbances due to vomiting can increase the risk of torsades.
