I am detoxing from long term use of Vicodin. I ve gotten through the runny nose, but now my blood pressure has spiked today. I am taking Lisinopril oral, 40mg, one-half tab 2 times a day. However, while on the Vicodin my blood pressure would get very low so I stopped taking the Lisinopril and my BP stayed relatively safe and level. I ve had 2 Lisinopril tabs today since 8 am and my blood pressure is still 168/104. Should I take any more, drink more water or what should I do? Thanks
