Hi and welcome to Healthcare Magic. Thanks for your question... Cipralex (Escitalopram) is an anti-depressant medication (called SSRIs) and can be used for the long term management of anxiety symptoms. Estrase (Estradiol) is a hormonal medication usually given to treat post-menopausal symptoms. Crestor (Rosuvastatin) is a medication given to treat high cholesterol. Now, I am presuming that you have had a detailed medical assessment before being started on these medication. As you have had 2 normal stress tests, your doctor must have ruled out any cardiac problem and is probably considering the rapid heartbeats to be due to anxiety. Sometimes, the symptoms you are experiencing could also be a part of post-menopausal syndrome, which may be the reason he has started you on Estrace. As long as you have had a proper medical evaluation and ruled out cardiac problems, you don t need to be so scared of these symptoms. Moreover, if they is due to a post-menopausal syndrome, then usually, they get better with time. You can try some relaxation techniques like deep breathing, progressive muscle relaxation, etc. and if your symptoms are very distressing, you can discuss with your doctor whether you need any additional anti-anxiety medication. All the best. - Dr. Jonas Sundarakumar Consultant Psychiatrist.
