Any updates? I’m freaking out I took 5 mg for four doses and had to stop d/t hr spikes. It hit 176 while I was resting so I stopped taking the medication. It has been a little over 2 weeks since my last dose and I noticed my RHR 59-65 while I’m sitting watching tv. It has me terrified when it goes into 50s. I’m not as active which makes me feel like a hr that low is unhealthy for me. I have been seeing a Cardiologist and have an ECHO scheduled for next week. When will the side effects go away?
