What causes weakness post Amlodipine intake?
Patient: 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 Doctor: Hello,  Your mentioned bp are readings are low, which is the cause for your weaknesses. We don't wish to initiate Amlodipine or other bp medicines unless bp is above 140. So it think you should discontinue the medicine and have some salt sugar water if bp falls below 100 or you continue to have weakness. Monitor your bp thrice a day using electronic home bp apparatus. Hope this helps you and get back if you have any doubts.
