Since it is the weekend, of course, I cannot speak with my internist who yesterday recommended I take Amlopdipine besylate 2.5 tabs, not because of high blood pressure, but perhaps related to his recommendation I take more salt in my diet. (I have not seen the results of blood work that is the reason for this, nor have I spoken to him--only to his assistant.) It s either a high or low reading of potassium? In any event, I took one tab last night at 7:30 but this morning felt weak, etc. so took my b.p. and it was 75/57/84; after breakfast and several hours later it was 84/70/72. At 12:35 this afternoon it was 101/71/73. I do not intend to continue taking this medicine until I get more information on Monday morning. (Normally I do not have any high blood pressure except last week, and this was corrected with different medication.) I realize it is difficult to comment without more information, but it helps to contact somebody. Pauline Cosyns, age 92
