Is there any reason why Gabapentin could potentially raise your heart rate? I took 1200mg yesterday and my pulse reached low 90s. Very high for me, I hover in the low high 50s to low 60s typically. Today I took another 1200mg and my pulse broke 100. I realize there’s a host of unknowns that could account for it where the gaba played no sole. But has anyone heard of this before?
