Just recently, during a Spin class I had trouble breathing. After several trips to the emergency room and the cardiologist's office, it has been determined that I suffer from a panic disorder. These particular attacks will last for hours with no relief in sight. One of the things I enjoyed most about my day was my morning work-out , but after the first panic attack, going to the gym only brought on more. After seeing a psychiatrist who put me on .5 mg of klonopin daily, I am able to exercise and am completely free of panic attacks. I usually take the klonopin a half an hour before working out, which allows me to exercise for two hours without the fear of a panic attack. My question is could intense exercise help metabolize the klonopin out of my system? The reason I ask is my husband and I were trying to get pregnant prior to the panic attack disorder. I feel that I need the medication at the moment, but I also understand that it is a risky drug for pregnancy.
