It is safe, but it made me extremely groggy. I took it with my first for nausea along with a vitamin B supplement, which was supposed to counteract the sleepiness and it didn't. I took that combo 2 or 3 times and couldn't shake being so groggy.
Thank you im 10 wks and finally about to get a prenatal visit but have always had trouble sleeping and have been taking it. I just dont want to hurt my lil one. But also have no sleep without it.
Yes it is safe. My doctor prescribed me unisom for nausea as well as for sleep.
