Does Gabapentin reduce heart rate? 

In this brief article, we will discuss whether Gabapentin may reduce heart rate and explore what to do if you experience a reduced heart rate as a result of taking Gabapentin. We will also examine research on reduced heart rate induced by Gabapentin and briefly mention the possibility of withdrawal symptoms and side effects associated with this medication.

Gabapentin is not known to reduce heart rate and there is no robust scientific evidence to attribute this effect to Gabapentin in humans (1,2). Only two pre-clinical studies, carried out with rodents, indicate this possibility (3,4).
