Active labor represents an absolute contraindication for administering Fentanyl because opioids can cross the placental barrier and affect the fetus.

When a woman is in active labor, especially if she is close to delivery, using opioids can lead to respiratory depression in the newborn, reduced fetal heart rate, or even a prolonged labor due to uterine atony. This could complicate the delivery process and potentially harm the baby. Thus, the use of Fentanyl in this context must be carefully considered, and alternatives may need to be employed to manage the mother's pain while ensuring the safety of the fetus during labor and delivery.

On the other hand, previous allergies may warrant caution but are not absolute contraindications unless there is a serious history of anaphylaxis. Dehydration can complicate pregnancy but does not specifically preclude the use of opioids unless it severely impacts the mother’s health or limits intravenous access. High blood pressure may require careful monitoring but is not, in itself, an absolute contraindication for the use of Fentanyl in a non-laboring
