Discussions that mention nifedipine

High & Low Blood Pressure board


Wow, Zuzu, I knew there were a lot of BP meds that you couldn't take with potassium, but not THAT many. Good to know. Also, when I woke up this morning, I went and looked up CCB's since those were not on your list. With drugs such as verapamil and diltiazem, potassium salts should be avoided, too, as both of those drugs work to bring down heart rate. (The other CCBs like nifedipine, amlodipine, etc, I couldn't find any information that stated that K salts would be a problem, as their primary mechanism of action is not to bring down heart rate.)


Yep, I knew digoxin was on that list...basically any drug that controls cardiac rhythm is not compatible with extra potassium. While most of those drugs are used only in a hospital (such as the positive inotropes), there are tons of people walking around at home taking digoxin, so that one completely bears repeating.

People with severe or uncontrolled hypertension shouldn't be taking the NSAIDs you mentioned anyway, because of their problem with water retention over the long term.
