I take Dyazide on a daily basis. My blood pressure usually runs on the low side about 110/80. Upon arrival at the hospital my blood pressure was 77/67 when I was in the emergency room . I was admitted for bilateral pneumonia. I was on intravenous sodium chloride for 3 1/2 days. I have been out of the hospital for three days. I have been out of the hospital for three days. During my hospital stay they did not allow me to take the Dyazide. Since I have left the hospital, my blood has been high. The last reading today was 143/77. Is it possible for the sodium chloride IV to cause this high blood pressure? I have resumed the Dyazide on Monday. Also, I have had a localized headache above my right eye. Thank you for reading.
