Answer to Question 1

ANS: A
The hydantoins cross the placenta and enter breast milk. Fetal hydantoin syndrome is possible with phenytoin, producing craniofacial abnormalities, congenital heart defects, and microcephaly, among other birth defects.

Answer to Question 2

ANS: A
Many drugs interact with triptans; the primary concern is sustained vasoconstriction and vaso-spasm leading to ischemia. These drugs include macrolide antibiotics, azole antifungal drugs, and ergotamine, caffeine, nefazodone, nelfinavir, ritonavir, and CYP 3A4 inhibitors.
