Something odd happened today with my heart rate

Summary

why would resting heart rate suddenly spike on reta

Users report occasional jumps in resting heart rate while taking reta, sometimes to over 100 bpm even when sitting still. A few saw the effect fade after weeks, one switched compounds because of it, and another experienced a single severe episode with dizziness and vomiting. Several note that monitor watches reveal short spikes even before starting the drug.

What this discussion establishesWhere people disagree

Whether the spikes are caused by reta or are normal variations that become noticeable only after starting a monitor

Still open

Why a single severe episode occurred for one user and never repeated

Nothing here is advice.

Normally my heart rate sits at 60-70 bpm when I'm just relaxing with nothing going on. Today it suddenly hit 109 while I was sitting on the couch. I'm taking 3 mg of reta plus daily KLOW and wonder if that's the reason, since nothing like this has happened before.

I've heard about resting heart rate going up with reta, which is one reason I avoided it.

I ran into the same thing fairly often on reta. The random spikes while doing almost nothing bothered me more than the higher baseline, so I switched to Tirz.

It only happened to me once at around 5 mg a week, though I'm now at 8 mg. I got dizzy, threw up, and it took about 30 minutes for my heart rate to fall below 100 bpm. No idea what triggered it, but it hasn't come back.

My resting rate rose roughly 8 bpm but returned to normal once I reached about 42 weeks.

Hard to tell from one incident. Since I started using a heart monitor watch I've seen all kinds of odd readings even before reta. Sometimes it alerts me to relax while I'm just sitting and feel fine. At night I get very brief sudden spikes. On reta my overall resting rate looks unchanged.

I saw a jump when I first began reta, but after a few weeks I stopped noticing it.

But is the increase still present even if you don't notice it?
