Talk to your doctor regarding medications - not Reddit.
Every individual is different and fasting without a plan or supervision while on meds - is just begging for trouble.
That being said, my non-medical advice is to monitor, monitor, and monitor your BP on a regular basis. Extended fasting does reduce your BP significantly.
I was on hypertension meds 10 months ago. After IF and EF, the doctor removed me off all meds.
Be safe, be careful and always talk to your doctor.
