My husband has been taking blood pressure medications in various combinations but is suffering mainly from leg weakness and tingling. Also burning soles and palms at times. Currently he is taking Benicar 20 mg, Amlodopine 2.5 mg and Eplerenone 50 mg. He was on Spironolactone. Which of these drugs is most likely to cause the leg weakness and tingling? The weakness is the most debilitating side effect. His potassium is normal.
