I've been having terrible heart palpitations and dizziness. I take 3 meds for blood pressure 1)Triam/HCTZ 50-25; 2)Amlodipine Besylate 5mg; and 3)Metoprolol 25mg. The reason I take 3 meds is because I tend to have bad side effects to other things. Do any of you have (or have you heard of) palpitations and dizziness from any of these meds? I did just google the Amlodipine and Metoprolol, and the palpitations can be a side effect, but I don't know about the dizziness. I'm concerned about a possible heart problem; however, I had this about 10 years ago, and nothing was wrong with my heart. Your input would be appreciated. StarGlitter. Note: I also have a severe panic disorder (that I've had for over 40 years) - but this was never one of my symptoms.
