I was diagnosed with high blood pressure and given Lisinopril. I have to get my bp down before taking my physical for work again and i was not sure how long i should wait before scheduling it. Answers (3) Blood Pressure medicine should start help to lower you blood pressure as soon as you take it. I am on BP medicine and I have a BP monitor so from my experience I took my pressure before my medication and then rechecked it in about a half hour.
