Pregnancy Interaction

• Be careful when using during pregnancy.
• There aren't many research on humans, but they don't suggest that it hurts the fetus too much.

• Ondansetron is usually the better choice for vomiting during pregnancy because there is more safety evidence on it.
• Breastfeeding: It's not certain if a lot of the medicine gets into breast milk, so only use it under a doctor's supervision.
