From the Guidelines
The management of neuropathy induced by rapid glycemic control in diabetes should focus on symptomatic relief while maintaining appropriate glycemic targets, with the primary recommendation being to slow the rate of glucose normalization. The goal is to achieve a gradual HbA1c reduction of approximately 1-2% over 3 months rather than rapid correction, as suggested by the most recent guidelines 1. For pain management, first-line medications include:
- Anticonvulsants such as pregabalin (starting at 50mg twice daily, titrating up to 300mg daily as needed) or gabapentin (starting at 300mg daily, increasing to 1800-3600mg daily in divided doses)
- Duloxetine (60mg daily) or amitriptyline (10-25mg at bedtime, increasing gradually) may also be effective, as recommended by recent studies 1. Topical treatments like capsaicin cream or lidocaine patches can provide localized relief. During treatment, blood glucose should be maintained in a slightly higher range temporarily (150-200 mg/dL) to prevent further nerve damage while allowing adaptation, as supported by the latest evidence 1. Symptoms typically improve within 3-6 months as the nervous system adjusts to the new glycemic state. This condition occurs because rapid normalization of blood glucose alters nerve perfusion and metabolic pathways that had adapted to chronic hyperglycemia, leading to oxidative stress and nerve damage. Patient education about the temporary nature of symptoms and the importance of continuing diabetes management despite this complication is essential for treatment adherence, emphasizing the need for a comprehensive approach that includes optimizing glucose management, blood pressure, and serum lipid control to reduce the risk or slow the progression of diabetic neuropathy 1.

Management Approach for Neuropathy Induced by Rapid Glycemic Control
The management approach for neuropathy induced by rapid glycemic control in diabetes involves careful consideration of the patient's glucose levels and the use of various pharmacologic and non-pharmacologic therapies.
- The initial step is to recognize the potential for neuropathy when rapidly correcting high serum glucose levels in diabetic patients, as highlighted in a study from 2.
- Gradual glycemic improvements should be encouraged to minimize the risk of microvascular complications, including diabetic neuropathy, as suggested by 3.
- First-line pharmacologic therapy for painful diabetic neuropathy includes gabapentinoids (pregabalin and gabapentin) and duloxetine, according to 4.
- Additional pharmacologic modalities, such as tapentadol and 8% capsaicin patch, may be considered as second-line agents, although studies have revealed modest treatment effects from these modalities 4.
- In cases of neuropathy refractory to conventional medical therapy, dorsal column spinal cord stimulation (SCS) may be an effective treatment option, as supported by level I evidence 4.
- Early recognition of acute diabetic neuropathies, such as treatment-induced neuropathy (TIN), diabetic lumbosacral radiculo-plexus neuropathy (DLPRN), and diabetic mononeuritis, is crucial to allow for early institution of appropriate pain-relieving medications, as emphasized in 5.
Key Considerations
- Clinicians should be aware of the potential link between acute tightening of glycemic control and acute neuropathies, as highlighted in 5.
- A high index of clinical suspicion is required to diagnose acute neuropathies, which are essentially a diagnosis of exclusion 5.
- The severity of neuropathy is tied to the change in the glycosylated hemoglobin A1C, and individuals with uncontrolled diabetes for prolonged periods are at high risk for developing treatment-induced microvascular complications, including neuropathy 3.
