Is it safe to take hormones after having a stroke and taking plavix (clopidogrel)?

Hormones & stroke. Which hormones are you talking about? Do you mean female hormones like estradiol? You should discuss the risks with your doctor.
Maybe. The clotting risk of newer hormones (especially lower dose estrogen pills without progesterone) is unclear; most of the data for abnormal clotting and increased stroke is based on old contraceptives with high doses of estrogen and progesterone. Though hormones are usually avoided in someone who's had a stroke, only your doctor can weigh the risks vs benefits of hormones in your case.
