It is actually quite common for your resting heart rate to decrease to around 48 beats per minute while taking a beta-blocker like Betacap (propranolol) 20mg. This medication works by relaxing your blood vessels and slowing your heart rate to reduce its workload. If you feel well, energetic, and are not experiencing symptoms like dizziness, lightheadedness, extreme fatigue, or fainting, this heart rate is generally safe and shows the medication is working. However, please share these readings with your doctor at your next visit, or contact them sooner if you start feeling unwell.
