Can Pregnant Women Use Latisse?

The
FDA has not approved Latissse for use during pregnancy. In order to approve it,
they would need to conduct studies on trial patients who were pregnant and no
one is willing to take the risk of harming an unborn child before we have the
answer. I am sure many women have used it before they realized they were
pregnant, but I doubt there will be a controlled study of the Latisse during
pregnancy.

It is always best to be cautious when deciding to use medications during pregnancy. Latisse's effects on pregnancy has not been studied, so it is advisable to be on the safe side and avoid using it while pregnant since it is used for cosmetic reasons.

To be on the safe side, I would recommend you stop using Latisse while pregnant. There is no research indicating the impact of the product on pregnancy, so it's always better to be safe than sorry.

Latisse is a category C drug so it is not recommended. There are no adequate or well controlled studies except for animal reproductive study but Latisse should only be administered during pregnancy only if the potential benefit justifies the potential benefit justifies the potential risk to the fetus. 

Latisse has NOT been tested on pregnant women and therefore should not be used until you ask your OB/GYN and receive the okay from your doctor.  Always better to be cautious and talk to your doctor first.

We physicians seem to get this sort of question a lot on Real Self.
I, and I vouchsafe, all physicians are very cautious during pregnancy. We always look at the risk/benefit ratio when determining whether a drug should be used during pregnancy. Since the benefit is purely cosmetic, the risk easily outweighs any benefit. Thus, I would wait until you have delivered your baby. Then you can use Latisse, providing you will not be nursing.
And congratulations!!
