Diagnosed with ER breast cancer almost four years ago, at 38 years old. It was stage one, with no lymph node activity. I had four chemo infusions over 12 weeks. After chemo was completed, I was put on monthly Lupron injections and a daily Anastrozole pill. I did not experience many side effects of either medication until about two years ago. By the time I started experiencing side effects, I had already been taking the medications for two years. The worst side effect has been the anxiety attacks, to the point where they feel like heart attacks and I’m being rushed to the emergency room. I have had several of these now, at random times, with no explanation, over the course of two years, and it is debilitating my daily life. I have been seen by a cardiologist, and my heart is just fine. I have been seen by a neurologist, and my brain is fine. I have never really been an anxious person throughout my life, and now, I get these attack at least three times per week. My PCP has prescribed me a small-dosed Ativan as a “rescue pill,” but I don’t certainly want to have to rely on something as strong as Ativan continuously. Recently, an ER doctor brought up that it could be the Anastrozole and that with hormones being depleted and blocked, there’s nothing in my body to combat any sort of stress or adrenaline-causing situations. I don’t live a very stressful life, at all. I drink one cup of coffee per day. I don’t smoke. And I really don’t live a very exciting life. I could be sitting on the couch watching tv, and these anxiety attacks come out of nowhere. I would love to know if anyone else out there has experienced any of this with Anastrozole, and any advice or help would be greatly appreciated. Very much so!
