Sedative effect of Diclectin

Date: 1999-12-13

I'm 27 weeks pregnant with my first, and am still having NVP. I've been on diclectin for 14 weeks. It had been working well for me but has made me so sleepy. I've learned that the drug can cross the placenta, so I'm just wondering that if it can make my baby sleepy too and if this will affect my baby's intellectual development in the future.

Diclectin is made of 2 different compounds: vitamin B6 and doxylamine. We know that some women who take Diclectin feel sleepy, while others do not. In both cases, Diclectin crosses the placenta. We do NOT know if the drug makes the baby sleepy, but we do know that it will not affect the baby's mental development. This drug has been used by over 33 million women during pregnancy and studies conducted to determine the safety of the drug have shown no increased risk for anatomical or mental developmental abnormality.
