tPA in pregnancy

Q: Alteplase (tPA) in pregnancy is? (select one)

A) Relative contraindication
B) Absolute contraindication


Answer: A

Alteplase (tPA) does not cross the placenta, but the risk exists due to hemorrhagic complications, which may lead to added complications in a pregnant patient with premature labor, placental abruption, or fetal demise. But in pregnant patients with life-threatening stroke, strong consideration should be given to tPA therapy.
