Researchers Challenge FDA Lamictal Safety Warning
Rutgers Health researchers say they have determined that GlaxoSmithKline’s antiseizure drug Lamictal (lamotrigine) is safe in older adults with epilepsy, contrary to an FDA safety warning. An online university post says that in 2020 FDA put a safety warning on the lamotrigine label based on reports the drug could increase the risk of heart conditions. Thus, it says, patients with epilepsy who might be good candidates for the treatment but had a history of heart issues could be precluded from being prescribed the drug.
Because the FDA warning came with a caveat that it was based on limited evidence, the Rutgers researchers wanted to further analyze the drug’s risks in epilepsy patients.
“It’s important for the public to know that our research found that lamotrigine is safe in older adults with epilepsy, including those with underlying heart disease,” the researchers say. The study was published 6/11 online in Neurology, the American Academy of Neurology journal.
The researchers say they looked at data from more than 158,000 adults with epilepsy and found no increased risk for heart rhythm problems or sudden cardiac arrest among older adults taking lamotrigine compared to those using levetiracetam (UCB’s Keppra and others), the other commonly prescribed anti-seizure drug. Study findings were consistent across a range of subgroups including age, gender, race, and those with histories of heart conditions, the researchers say.
