Giving medicines to pregnant women can be tricky. Here are some of the main challenges:

• Safety Worries: There is a big concern about whether some medicines can harm the baby.
• Not Enough Research: We don't always have enough strong information about how drugs affect pregnant women.
• Individual Needs: Every woman is different. Her health and genetic makeup can make picking the right medicine harder.
• Rules and Regulations: There are many guidelines to follow, which can make things even more complicated.

It's important to find the right balance to keep both the mother and the baby healthy.
