Your prescribed medication contains olmesartan. While anxiety and a fast heart rate are uncommon side effects, please do not stop taking it abruptly, as this can cause a sudden spike in blood pressure. Ayurvedic remedies like Sarpagandha, Arjuna, and Ashwagandha can help manage blood pressure and anxiety. However, they should only be started under professional guidance and cannot immediately replace your medication. Please consult your doctor immediately to discuss these symptoms. They can safely evaluate you and might transition you to alternative prescription medications, such as beta-blockers, which effectively lower blood pressure while also controlling a fast heart rate and anxiety.
