Are you aware that some common medications for nerve pain could be setting off a dangerous chain reaction of unnecessary prescriptions, especially for older adults? It's a phenomenon called a 'prescribing cascade,' and it's more common than you might think.
Often, doctors prescribe drugs like gabapentin (Neurontin) to manage nerve pain. However, these medications can sometimes cause side effects that are misinterpreted, leading to more prescriptions and a cycle of adverse reactions.
In a concerning scenario, gabapentinoids, including gabapentin and pregabalin (Lyrica), can cause leg swelling. This symptom might lead doctors to suspect heart failure and prescribe diuretics. But here's where it gets controversial: diuretics can cause kidney problems, dizziness, and increase the risk of falls.
Researchers looked at the medical records of 120 older veterans, mostly men, who were taking several medications. All of them had used gabapentinoids and then started taking loop diuretics, which are used to treat fluid buildup.
Dr. Michael Steinman, a professor at UCSF, pointed out that doctors often see gabapentinoids as safe, and their use has nearly doubled in the last decade. He suggests that patients should regularly check with their doctors to see if these medications are still the best option and consider non-drug alternatives.
Interestingly, after taking gabapentinoids, patients developed leg or foot swelling. However, only 4 of the veterans' doctors considered the medication as the cause, while 69 looked for other reasons. They suspected heart failure or venous stasis, a condition where blood flow issues can cause swelling. Even though none of the veterans had these conditions before taking gabapentinoids, only one doctor stopped the medication. Almost 1 in 5 patients underwent imaging to rule out serious conditions.
And this is the part most people miss: All the doctors, even those who suspected gabapentinoids, prescribed loop diuretics. Within two months, 28 patients experienced side effects like kidney problems, dizziness, blurred vision, and electrolyte imbalances. Six patients even ended up in the hospital or the emergency room.
Gabapentinoids might be prescribed at high doses or for conditions where they aren't helpful. Doctors should consider reducing the dose or avoiding these drugs to prevent prescribing cascades and other side effects.
Dr. Matthew Growdon, the lead author of the study, highlights this issue.
