<s>[INST] I went to the doctor the day before yesterday. My blood pressure was 160/104. He put me on BP meds and would not let me leave until My BP was below 100. I have been on BP before but ran out and forgot about it. Now my BP is 176/122, I have taken 3 10mg lisprinsoral. Is this dangerous? [/INST] Hi There I understand your concern and I would like to tell you that LISINOPRIL belongs to ACE INHIBITOR family of antihypertensives and is a good medicine to control blood pressure. But it's not advisable to take any medicine at any dose as per your choice. Taking a dose more than required of Lisinopril can make your BP fall to below normal levels due to which you can go unconscious. Take your meds as advised by your doctor wish you good health </s>
