I Have Been Taking Florinef For Many Years. I Have

I have been taking Florinef for many years. I have been taking .2mg daily, 2 pills. My doctor recently decreased me to one pill, 0.1mg, due to very high blood pressure. After two weeks my doctor wants me to cut the pill in half, so I am slowly tapering. How long will Florinef stay in my system, before I can hopefully see my blood pressure drop? Thank you for your help
