just had a para med for life insurance was taking 20 mg of Lisinopril, but my blood pressure got higher so went up to 40mg, but still sometimes change my dosage back to 20mg... been taking only 20 mg for the last couple of days this morning, about 1 to 2 hours before the para medical lady came I took 40 mg, but my blood pressure was 162 / 102... do you suppose that was enough time to kick in ???
