Why does my heart rate spike suddenly and cause dizziness when I stand up or walk, even though my heart tests are normal, and could this be related to my anxiety medications, Serta and Alprax?
What you are experiencing?a sudden heart rate spike and dizziness when standing?can be related to how your body regulates blood pressure. Your anxiety medications, Serta (sertraline) and Alprax (alprazolam), can indeed play a role. Sertraline can affect your nervous system's control over heart rate, while alprazolam can sometimes lower blood pressure, contributing to dizziness when you change positions. Please stay reassured, as this is a known and manageable side effect. I recommend discussing this with your prescribing doctor, who can check your sitting and standing blood pressure to help tailor your treatment safely.
