Gabapentin use may lead to adverse drug events, polypharmacy

Posted on

In an effort to reduce postoperative opioid prescribing, non-opioid pain medication such as gabapentin, is prescribed more often, however, a recent study shows that prolonged use of gabapentin is a potential issue that may increase the risk of adverse drug events and polypharmacy.

 Amongst, 17,970 patients >65 years old without prior gabapentinoid use who underwent common non-cataract surgical procedures and had a new prescription for gabapentin after surgery, prolonged use (a fill>90 days after discharge) was reported in 22%. Prolonged use was more likely in women (64% vs 61%), those who were non-White (14% vs 12%), those with concurrent prolonged opioid use (44% vs 18%), and those who had undergone emergency surgery (8% vs 4%).

On multivariable analysis, prolonged use of gabapentin was associated with:
-Being female
-Having a higher Charlson comorbidity score
-Having an opioid prescription at discharge and at >90 days
-Having a higher care complexity
