Our surgery has a blood pressure machine in the waiting area, in fact my husband had a letter asking him to take his blood pressure and to hand the print out into reception. He has relatively high blood pressure so he was prescribed enzalutamide instead of abiraterone , apparently enzalutamide has slightly less effect on high blood pressure than abiraterone. But you father' s is very high. When my husband began enzalutamide he checked his blood pressure at home and found it to be high , his g. p. Suggested increasing his blood pressure medication until he gets to se his consultant oncologist .h, e sees her next week so it will be interesting to see what she says. She did mention that chemotherapy reduces blood pressure but imnot sure he wants to go down that path until necessary
