What is the typical dosage of propranolol given to someone with anxiety/panic disorder?

Depends: First thing is be clear that you have panic disorder, versus panic attacks due to a medical cause. Next, the doctor needs to know that you do not have asthma or diabetes or any trouble with your heart ryhthm. When I use it with my patients, I sometimes start at a low dose twice per day. If one starts off with a large dose, it can cause slowed heart rate, low blood pressure, and fatigue.
