A client with diabetic neuropathy reports a burning, electrical-type pain in the lower extremities that is worse at night and not responding to nonsteroidal anti-inflammatory drugs. Which medication will you advocate for first?

• A. Gabapentin (Neurontin)
• B. Corticosteroids
• C. Hydromorphone (Dilaudid)
• D. Lorazepam (Ativan)

Answer: (A)

Neuropathic pain from diabetic neuropathy is best treated with medications that specifically modulate nerve pain, not with anti-inflammatory drugs. Gabapentin works by binding to calcium channels in the central nervous system, which reduces excitatory neurotransmitter release and dampens abnormal nerve firing that causes burning, electric-type pain. It’s a first-line option for diabetic neuropathy and can help with nighttime pain, improving sleep as the pain intensity decreases.

NSAIDs target inflammation and are not effective for neuropathic pain. Corticosteroids would address inflammation rather than the nerve pain in this scenario. An opioid like hydromorphone can provide some analgesia but neuropathic pain often responds inadequately to opioids alone and carries risks such as tolerance, dependence, and CNS depression. A benzodiazepine like lorazepam doesn’t treat pain and adds sedative risks, especially at night.

Starting gabapentin addresses the underlying mechanism of this pain and aligns with standard first-line therapy, making it the best initial choice.
