A friend just text me, her Dr., changed her B/P medication from Amlodipine to half of 2.5 Iosaltan because her legs were swelling up, she now says this pill isn t working? When should she do now. PS I ve enclosed her email, so you can directly speak to her. She also needs someone whom can speak Spanish, should that matter. Thanking you in advance. A.M.S.
