<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello. I took an Emergen C pack 1,000mg and now I feel like my heart is racing and a little shortness of breath. Should I take maybe half and take it every other day? I like it because I m not big on taking pills and this is a lot easier. I sort of have a headache as well. Any thoughts?  <response>: Hi welcome to Chat Doctor. I understand your query and concern. Shortness of breath in your case needs through assessment for the cause. I advise you to have a baseline 2 dimensional echocardiography, ECG and lipid profile to assess the basic cardiac reserve of your heart. Restrict the intake of salt to less than 6gday. Regular physical exercise in the form of brisk walk for 20 min a day for 5 days a week is pretty useful. Chat Doctor. Emerged C 1000 mg has to be taken as full tablet every other day for good effect. Reduce the intake of fatty and fried food. One pomegranate a day will help to keep your heart at good pace without clot formation. Consult a Cardiologist for further expert management. Post your further queries if any. Thank you.
