When I was prescribed Terbinafine, the pharmacist was concerned about a drug interaction with Metoprolol. All my doctors said it was okay to take both medication but to watch my pulse rate in case the drug interaction induces bradycardia. Here is a plot of my resting heart rate as measured by my Fitbit tracker.
I started taking the Terbinafine on 1/12 which is when my pulse starts to drop from 65 to 60 on average. Is that statistically significant? Bradycardia is usually defined as <60 bps so should I wait until it drops to 59?
