42 Do not forget to instruct your patients on ACEi or ARB s and diuretics To report too much sweating, fever, diarrhea, or vomiting. To be sure to drink enough fluids to prevent dehydration. Before having surgery, to tell their doctor or dentist about all the products they use (including prescription drugs, nonprescription drugs, and herbal products). To avoid NSAIA s, potassium supplements or salt substitutes that contain potassium.

Report From the Panel Members Appointed to the Eighth Joint National Committee (JNC 8) Recommendation 4 In the population aged 18 years with chronic kidney disease (CKD), initiate pharmacologic treatment to lower BP at SBP 140 mm Hg or DBP 90 mm Hg and treat to goal SBP <140 mm Hg and goal DBP <90 mm Hg. (Expert Opinion Grade E) Recommendation 8 In the population aged 18 years with CKD, initial (or add-on) antihypertensive treatment should include an ACEI or ARB to improve kidney outcomes. This applies to all CKD patients with hypertension regardless of race or diabetes status.
