I Was Taking Cold Meds And Appetite Suporessant Began Having

I was taking cold meds and appetite suporessant began having high blood pressure when I realized it must be those two things I stopped taking them 3 days later doc pute on 5 MG lisenopril. After 2 pills blood pressure dropped 99 /73 so I didn't rake anymore meds. Been two days it's came up to 117/76 . How long before it wears off ?
