Hi, My name is Donna, I went to a new MD on this past Wed and my BP was196/100 while on Metoprolol Tartrate 25 mgs 2x daily. She changed my medication to Amlodipine Besylate 5 mgs as well as Citalopram 10 mgs (anxiety). I took both pills starting Wed night and by Thursday night I was having horrible symptoms. Anxiety, restlessness, nausea, vomiting (aggravating my acid reflux), could not sleep - so, after taking the Citalopram for 3 nights, I stopped and am just taking the Amlodipine 5 mgs. Now I m having this horrible burning in my mouth, throat and chest. I m starting to panic. What should I do?
