Response: Gabapentin has shown promise in treating nerve-related pain, and it has become a popular choice to treat chronic low back pain, despite limited evidence. Currently, there is a discrepancy on whether taking gabapentin increases a patient’s risk for developing dementia.

Our main findings were that gabapentin prescription was associated with an increased risk for dementia and mild cognitive impairment. This risk was pronounced in younger adults (age 18-64). Moreover, the incidence of dementia and mild cognitive impairment was higher in those prescribed gabapentin 12+ times compared to those prescribed gabapentin 3-11 times.

Response: Our study focused on chronic pelvic pain in women, a common condition affecting up to one in four women, for which there are few evidence-based treatment options. We previously conducted a multicentre randomised controlled trial (GaPP2) to assess the effectiveness of gabapentin, a commonly prescribed painkiller, in relieving chronic pelvic pain.

The trial found that gabapentin did not relieve pain and was associated with more side effects compared to a placebo. However, to better understand why some women respond to gabapentin more than others, we studied the DNA of the participants from the GaPP2 trial to identify genetic changes that might affect response to gabapentin.

Response: Gabapentin is one of the most commonly prescribed psychotropic medications, as it is used (primarily off-label) to treat a myriad of conditions, ranging from anxiety disorders and insomnia to chronic pain, seizure disorders, and substance use disorders.
This is even more true for individuals receiving treatment for opioid use disorder, who often have multiple physical and mental co-morbid conditions.

Unfortunately, it  has increasingly been found in people who overdose, causing physicians and policymakers to consider restricting access to gabapentin and tapering/deprescribing it in stable patients taking it in the long-term.
