I went to my gp today and explained about high levels of anxiety. Dr prescribed propranolol.
The thing is I also spoke with her about having my heart health tested due to family history of heart attacks, sudden death, close family being tested for Brugada Syndrome. She is going to give me an ecg, blood test and cholesterol test.
Reading through the pamphlet it says to be careful taking this medication with heart issues 
Should I take it or not? What are the chances of them prescribing something dangerous?
