can cause elevation of blood pressure, but such a severe rise of blood pressure, also called malignant hypertension
is only rarely seen with Endep. There have been only a few case reports describing this. In addition to Endep, stress
could also have contributed to some extent to the rise in your blood pressure. If the dose of Endep was hiked up very fast, this could also have been responsible. I feel that in future, apart from avoiding medicines like Endep, you should also try to ensure that you are not too stressed.
Hope this helps you. Best wishes.
