Diabetic Neuropathy Medications: A Concise Guide for Treatment Options

Diabetic neuropathy is a prevalent complication of diabetes mellitus, which results in nerve damage due to persistently high blood sugar levels. This condition can manifest in various forms, causing chronic pain, gastrointestinal problems, dizziness and weakness, as well as urinary or sexual complications. The management of diabetic neuropathy mainly involves controlling blood sugar levels to prevent further nerve damage, coupled with administering medications that alleviate the pain and discomfort caused by the condition.

Several medications have been proven effective in treating pain caused by diabetic neuropathy. These include anti-seizure medications like pregabalin (Lyrica) and gabapentin (Gralise, Neurontin), which can help manage mild to moderate nerve pain. Still, they may cause side effects like drowsiness, dizziness, and swelling in the hands and feet source. In addition, antidepressants are often prescribed for pain relief, even in patients who do not experience depression, as they can be effective in mitigating nerve-related discomfort.

Topical creams and transcutaneous electronic nerve stimulation (TENS) therapy are also viable treatment options for diabetic neuropathy source. It is crucial to consult a healthcare professional before opting for any medication, as they can guide you to the best-suited treatment plan considering your specific symptoms, and potential side effects.

Types of Diabetic Neuropathy

Diabetic neuropathy refers to a group of nerve disorders caused by diabetes. There are four main types of diabetic neuropathy: Peripheral Neuropathy, Proximal Neuropathy, Autonomic Neuropathy, and Focal Neuropathy. Each type affects different nerves and presents with varying symptoms.

Peripheral Neuropathy

Peripheral neuropathy is the most common form of diabetic neuropathy, affecting the nerves that serve the extremities such as hands, feet, and legs. Symptoms often begin in the feet and gradually progress along the limbs, causing:

  • Numbness or reduced ability to feel pain or temperature changes
  • Tingling or burning sensation
  • Sharp pains or cramps
  • Increased sensitivity to touch

Proper foot care and medications such as serotonin and norepinephrine reuptake inhibitors (SNRIs) can help manage the symptoms of peripheral neuropathy. The ADA recommends duloxetine (Cymbalta, Drizalma Sprinkle) as a first-line treatment.

Proximal Neuropathy

Proximal neuropathy, also known as diabetic amyotrophy, primarily affects the hip, buttock, and thigh areas. It is more common in older adults with type 2 diabetes and can cause severe pain in these areas alongside muscle weakness. Physical therapy and pain management using medications like SNRIs may offer relief from proximal neuropathy symptoms.

Autonomic Neuropathy

Autonomic neuropathy involves damage to the nerves controlling the internal organs, processes, and systems such as the heart, digestive system, sexual organs, urinary tract, and sweat glands, as mentioned by Johns Hopkins Medicine. Symptoms vary depending on which organs are affected and can include:

  • Gastrointestinal issues (e.g., gastroparesis, diarrhea, or constipation)
  • Cardiovascular problems (e.g., irregular heart rate or orthostatic hypotension)
  • Erectile dysfunction or vaginal dryness
  • Urinary problems (e.g., difficulty starting urination or urinary incontinence)

Treatment for autonomic neuropathy typically targets the specific organs affected, with medications or therapies aiming to manage the symptoms.

Focal Neuropathy

Focal neuropathy results from damage to a single nerve or a group of nerves, often affecting specific body parts such as the head, torso, or legs. This type of neuropathy can cause sudden and severe pain, muscle weakness, or loss of muscle function. The symptoms of focal neuropathy may improve over time with proper treatment and management.

Causes and Risk Factors

Diabetic neuropathy, a nerve-related complication, affects individuals with both type 1 and type 2 diabetes. Several factors contribute to the development of this condition. Understanding these causes and risk factors can help people better manage their diabetes and prevent or delay the onset of neuropathy.

High Blood Sugar

Poor blood sugar control is a major cause of diabetic neuropathy. Prolonged exposure to high blood sugar damages nerves throughout the body, making them more susceptible to dysfunction. Maintaining healthy glucose levels through diet, exercise, and medication is crucial in reducing this risk.


Smoking constricts blood vessels and impairs blood circulation, which can exacerbate nerve damage in individuals with diabetes. Quitting smoking is an important lifestyle change that can significantly decrease the risk of developing diabetic neuropathy.

Blood Pressure and Cholesterol

Elevated blood pressure and high cholesterol levels can hinder blood flow to nerves, increasing the risk of nerve damage. Managing blood pressure and cholesterol through medication, dietary changes, and exercise can contribute to preventing or delaying the onset of neuropathy.

Lifestyle Factors

Certain lifestyle factors such as excess alcohol consumption or malnutrition can increase the risk of diabetic neuropathy. Adopting healthier habits, including limiting or avoiding alcohol intake and maintaining a balanced, nutrient-rich diet, is essential in minimizing the risk of nerve damage.

Although lifestyle changes can help to prevent or manage diabetic neuropathy, it is essential to consult a healthcare professional for appropriate guidance and treatment. Regular medical check-ups and early intervention are crucial in mitigating the risks and potential complications of diabetic neuropathy.


Diabetic neuropathy can manifest in a variety of ways, depending on the type of neuropathy and the nerves affected. Some common symptoms include:

  • Numbness and tingling: These sensations often start in the legs, feet and hands, and gradually progress toward the center of the body. This loss of sensation can lead to difficulties with coordination and balance.

  • Pain: Patients may experience sharp or burning pain in the affected areas. Pain can be intermittent or constant, and can range from mild to disabling.

  • Temperature sensitivity: Some individuals with diabetic neuropathy may become more sensitive to changes in temperature, especially in the extremities.

  • Muscle weakness: In some cases, muscle weakness is observed in the affected areas, particularly in the thighs and hips. This can make it difficult for patients to walk or perform daily activities.

In addition to the above, diabetic neuropathy can have more specific symptoms based on the nerves affected, such as:

  • Autonomic neuropathy: This type of neuropathy can cause problems with the digestive system, urinary tract, blood vessels, and heart. Symptoms may include digestive problems, low blood pressure, and impaired perception of pain.

  • Cranial neuropathy: When neuropathy affects the nerves responsible for eyesight and facial movement, patients may experience symptoms such as double vision or difficulty maintaining balance.

  • Focal neuropathy: This subtype of neuropathy affects a single nerve or group of nerves, resulting in sudden and severe pain. It can cause chest pain when affecting nerves in the chest area.

  • Diabetic foot ulcers: Due to the decreased sensation in the feet, people with diabetic neuropathy are at an increased risk of developing ulcers and infections in the feet. This can lead to serious complications if not promptly treated.

It is crucial for individuals with diabetes to closely monitor their symptoms and promptly consult with their healthcare providers if they suspect the presence of diabetic neuropathy. Early detection and management can significantly improve quality of life and prevent further complications.


Diagnosing diabetic neuropathy involves a combination of methods including nerve conduction studies, electromyography, physical exam, and review of medical history. These tests help identify the severity and type of nerve damage in order to recommend appropriate treatment options.

Nerve Conduction Studies

Nerve conduction studies evaluate the speed and strength of signals transmitted through the nerves. They can reveal nerve damage and help determine the underlying cause. During this test, electrodes are placed on the skin and small electric shocks are delivered to stimulate the nerves. The speed and amplitude of the nerve signals are then recorded and analyzed.


Electromyography (EMG) measures the electrical activity of muscles during contraction and at rest. This test can detect muscle weakness and help determine if the cause is due to nerve damage or muscle dysfunction. During an EMG, a needle electrode is inserted into the muscle, and the electrical activity is recorded when the muscle is at rest and during contraction.

Physical Exam

A physical exam for diagnosing diabetic neuropathy includes:

  • Checking muscle strength and reflexes: This helps identify muscle weakness or altered reflexes that might indicate nerve damage.
  • Assessing sensitivity to touch, temperature, and vibration: Loss of sensation or altered sensitivity might indicate nerve damage. Tools such as a tuning fork or nylon filament may be used to assess sensitivity.

Medical History

A thorough review of the patient's medical history is crucial in diagnosing diabetic neuropathy. In this review, the healthcare professional will consider:

  • Duration of diabetes: Nerve damage is more likely in patients who have had diabetes for a longer period.
  • Blood sugar control: Poor blood sugar control increases the risk of nerve damage.
  • Presence of other diabetic complications: Co-existing kidney or eye issues might be indicative of diabetic neuropathy as well.
  • Existing symptoms: Symptoms such as numbness, tingling, or pain in the limbs can point towards diabetic neuropathy.

By using a combination of nerve conduction studies, electromyography, physical exam, and review of medical history, healthcare professionals can accurately diagnose diabetic neuropathy and recommend appropriate treatment options.

Treatment and Medications

Blood Sugar Control

A crucial aspect of managing diabetic neuropathy is to maintain optimal blood sugar levels. Controlling blood glucose levels through diet, exercise, and medication will help reduce the progression of neuropathy and its complications.

Oral Medications

Several oral medications can be used to alleviate symptoms associated with diabetic neuropathy. Some choices include:

  • Anticonvulsants: Pregabalin and gabapentin are often prescribed for relieving neuropathic pain. Both drugs work by targeting calcium channels and reducing the release of neurotransmitters in the brain.

  • Antidepressants: The American Diabetes Association (ADA) recommends duloxetine as a first-line treatment for diabetic neuropathy, as it can alleviate pain and improve overall well-being. Another option is venlafaxine, which may have similar effects. Antidepressants can be combined with anticonvulsants for better results, but side effects like nausea, dizziness, and constipation should be monitored.

Topical Treatments

For localized pain relief, topical treatments can be applied directly to the skin. Some examples are:

  • Capsaicin cream: Capsaicin, derived from chili peppers, can help relieve pain by desensitizing skin nerve receptors. It can be found in over-the-counter gels and creams, but may cause burning or stinging sensations in some individuals.

Supplementary Options

In addition to conventional pharmaceutical treatments, there are supplementary options for managing neuropathic pain:

  • Alternative therapies: There are alternative treatments or natural remedies available, but their efficacy may not have been scientifically tested to the same degree as conventional medications.

  • Tricyclic antidepressants: While not a first-line treatment, tricyclic antidepressants like amitriptyline and nortriptyline can also help with neuropathic pain management. These drugs work by increasing levels of certain neurotransmitters in the brain, thus alleviating pain.

It's essential to consult with a healthcare professional for personalized advice on managing diabetic neuropathy, as they can recommend the most suitable treatments and adjustments for individual needs.

Lifestyle Changes

In managing diabetic neuropathy, lifestyle changes play a vital role alongside medications. By incorporating these changes into your daily routine, you can significantly improve your overall health and reduce neuropathy symptoms.


A balanced and nutritious diet is essential for individuals with diabetic neuropathy. Making healthier food choices can help regulate blood sugar levels, maintain a healthy weight, and reduce neuropathy symptoms. Some important tips for a neuropathy-friendly diet include:

  • Consuming a variety of fruits, vegetables, whole grains, and lean proteins
  • Limiting processed foods, saturated fats, and sugars
  • Eating smaller, more frequent meals to prevent blood sugar fluctuations
  • Drinking plenty of water and avoiding excessive alcohol intake

Mayo Clinic provides valuable information on dietary changes that can help relieve symptoms of diabetic neuropathy.


Regular physical activity can help manage blood sugar levels, maintain a healthy weight, and improve nerve health. It is advisable to engage in at least 150 minutes of moderate aerobic exercise per week, such as walking or swimming, as well as strength training exercises. However, it is essential to consult with your healthcare provider before beginning an exercise program to ensure its safety and effectiveness given your individual health condition.

Blood Sugar Control

Achieving optimal blood sugar control is vital for individuals with diabetic neuropathy. Continuous monitoring and management of glucose levels can help prevent further nerve damage and reduce neuropathy symptoms. Consult with your healthcare provider to establish appropriate blood sugar targets and develop a personalized diabetes management plan.

Some essential tips for better blood sugar control include:

  • Regularly checking your blood glucose levels
  • Taking prescribed diabetes medications as directed
  • Working closely with your healthcare provider to adjust medications when needed

Johns Hopkins Medicine offers more information on the significance of controlling blood glucose levels in the treatment of diabetic neuropathy.

Weight Management

Maintaining a healthy weight is crucial for those with diabetic neuropathy, as excess weight can negatively impact blood sugar control and increase the risk of complications. By combining a well-balanced diet and regular physical activity, individuals with diabetic neuropathy can work towards achieving and maintaining a healthy weight. Additionally, healthcare providers can offer personalized recommendations and support for effective weight management strategies.

Managing Complications

Diabetic neuropathy can lead to various complications that require proper management. In this section, we will discuss the management of wounds and infections, sexual dysfunction, gastroparesis, and orthostatic hypotension.

Wounds and Infections

Diabetic neuropathy can result in ulcers, wounds, and infections due to decreased sensation and blood flow in extremities. Proper wound care and management is essential to promote healing and prevent complications. Some strategies include:

  • Cleansing the wound regularly
  • Using appropriate dressings to maintain a moist environment
  • Offloading pressure from the affected area
  • Seeking medical care for signs of infection (redness, warmth, pus) or if the wound does not heal

Sexual Dysfunction

Diabetic neuropathy can cause sexual dysfunction in both men and women. Common issues include erectile dysfunction in men and vaginal dryness or painful intercourse in women. Potential treatments may involve:

  • Medications for erectile dysfunction (e.g., sildenafil)
  • Vaginal lubricants or moisturizers
  • Hormonal therapy (e.g., estrogen replacement)
  • Pelvic floor physical therapy
  • Psychological counseling


Gastroparesis is a complication of diabetic neuropathy that affects digestion, causing symptoms like nausea, vomiting, and constipation. Management of gastroparesis typically involves:

  • Dietary modifications, such as eating small, frequent meals and avoiding high-fat or high-fiber foods
  • Medications to promote gastric emptying (e.g., metoclopramide)
  • Antiemetic drugs to manage nausea and vomiting (e.g., ondansetron)
  • In severe cases, alternative nutrition methods, such as enteral or parenteral nutrition

Orthostatic Hypotension

Orthostatic hypotension is a drop in blood pressure that occurs when moving from a sitting or lying position to standing. It can lead to dizziness, weakness, and even fainting. Management of orthostatic hypotension involves:

  • Gradually changing positions to allow the body to adjust
  • Wearing compression stockings to improve blood flow
  • Staying hydrated and increasing salt intake (if advised by a healthcare provider)
  • Medications to increase blood pressure, such as fludrocortisone or midodrine
