High Blood Pressure
Salt substitute with Atenolol and Felodipine
My husband was recently told to cut out salt. Can we use a salt substitute with Atenolol ( 50 mg per day) and Felodipine ( 10 mg 2 times per day)??
Many salt substitutes contain potassium. Atenolol is a beta blocker and can raise blood potassium levels. In people with normal kidney function, the increase in usually small.
Many experts recommend to measure a blood potassium level a few weeks after starting a beta blocker, especially when one increases the potassium in the diet. If high potassium levels occur, they often respond to the addition of a diuretic.
