M 69 year old husband takes lisinopril 20 mg each morning.  Weve been taking his blood presure at 7
The blood pressure you have mentioned is on the lower side, and it explains the tiredness he is feeling.  Maybe lisinopril at 20 mg is more powerful for him and the erratic consumption OD medication may add to the fluctuations in blood pressure is far worse than not taking any medication.  I would suggest you take 10 mg lisinopril every day at a foxed time, if th3 blood pressure is still more than 140 / 90 than only increase the dosage. Regards Chat Doctor.
