Prolonged use of Lyrica, a medication containing pregabalin, has been associated with cognitive impairment, particularly in regards to memory, [1].
Lyrica works by modulating the activity of neurotransmitters in the brain, which can lead to a range of side effects, including changes in cognitive function [2]. Research indicates that pregabalin may interfere with memory formation and retrieval, potentially causing difficulties in learning and retaining new information [3].
According to a study published in the journal Neuropsychopharmacology, long-term use of pregabalin (at doses similar to those used in clinical settings) was found to impair memory performance in healthy participants [4]. The researchers suggested that this impairment may be due to the medication's effects on GABA receptors, which play a crucial role in synaptic plasticity and memory consolidation [5].
Another study in the Journal of Clinical Psychopharmacology reported that patients taking pregabalin for epilepsy or neuropathic pain experienced cognitive side effects, including memory problems, although the severity and frequency of these effects varied widely [6].
The FDA has also included cognitive impairment, including memory problems, as a potential side effect of pregabalin in their labeling, noting that this effect may occur at any time during treatment [7].
It's essential to note that not everyone taking Lyrica will experience memory problems, and the severity of these side effects can vary depending on the individual and their treatment duration [8]. If you're taking Lyrica and notice concerns about your memory, consult your healthcare provider to discuss potential adjustments to your treatment plan [9].
