Any medication used excessively can harm a fetus. You need to speak with your doctor, unless the benefits outweight the risks it is imperitive that you take steps to quit taking this medication now. At the very least, if you continue to take this medication throughout your pregnancy your baby could be born and experience withdrawal symptoms, which can be dangerous.
Yes it can hurt the baby IF you are taking it everyday.
Yeah that is not safe at all. She should not be taking them.
Thats really not good for the baby! I would tell her that and ask her to stop taking them! It would be much safer for the baby
