Alternative Treatment Options for Nerve Discomfort: Categories, Mechanisms, Potential Adverse Reactions
Neuropathic pain, a condition resulting from damage to nerves, affects approximately 2.4% of the population, rising to 8% among older adults [1]. This condition can be debilitating, but several pharmacological treatments are available to help manage the pain. However, these treatments often come with side effects that patients should be aware of.
Anticonvulsants are first-line medications for managing neuropathic pain. Common side effects of anticonvulsants, such as pregabalin and carbamazepine, include drowsiness and dizziness, loss of coordination (ataxia), blurred or double vision, tremors, cognitive effects like confusion, memory impairment, difficulty concentrating, and mood changes including irritability or depression [3][5]. Gastrointestinal symptoms like nausea, vomiting, constipation, dry mouth, and diarrhea are also common. Notable with pregabalin is peripheral edema (leg swelling) [3]. Rare but serious reactions include allergic reactions (e.g., angioedema, rash), suicidal thoughts or behavior, and blood disorders like thrombocytopenia or neutropenia [3].
Antidepressants, particularly tricyclic antidepressants (TCAs) and serotonin-noradrenaline reuptake inhibitors (SNRIs), are also used to treat neuropathic pain. Common side effects of these antidepressants include drowsiness, dizziness, dry mouth, constipation, and fatigue [2]. There is a potential for serotonin syndrome with certain combinations, and an increased risk of bleeding events, especially when combined with anticoagulants or NSAIDs. Mood effects like agitation, anxiety, insomnia, or depression exacerbation may also occur [2]. Caution is advised in patients with a seizure history, glaucoma, or arrhythmias due to side effects like sedation, arrhythmias, and urinary retention.
Opioids, such as tramadol, are sometimes used to treat neuropathic pain. The most frequent side effect is constipation, often requiring prophylactic bowel regimens. Other common adverse effects include drowsiness, dizziness, nausea, dry mouth, urinary retention, orthostatic hypotension, and potential sedation. In elderly or frail patients, there is an increased risk of sedation and cognitive impairment. There is also a risk of tolerance, dependence, or misuse of opioids, potentially leading to opioid use disorder [2].
In summary, drowsiness, dizziness, cognitive impairment, gastrointestinal symptoms, and coordination problems are the most notable common side effects across these drug classes when used for neuropathic pain. Serious side effects such as allergic reactions, suicidal thoughts, and seizures are less common but important to monitor [1][2][3][5].
It is essential for patients to discuss the potential side effects of these medications with their healthcare providers to make informed decisions about their treatment options.

- Neuropathic pain, a chronic-disease affecting 2.4% of the population and rising to 8% among older adults, can be managed with various pharmacological treatments.
- Anticonvulsants, like pregabalin and carbamazepine, are first-line medications for neuropathic pain, but they can cause side effects such as drowsiness, dizziness, and gastrointestinal symptoms.
- Pregabalin, in particular, may cause peripheral edema (leg swelling), while antidepressants like tricyclic antidepressants (TCAs) and serotonin-noradrenaline reuptake inhibitors (SNRIs) can lead to drowsiness, dizziness, and mood changes like depression.
- Opioids, such as tramadol, are sometimes used for neuropathic pain treatment, but they often cause constipation, drowsiness, and potential sedation, increasing the risk in elderly or frail patients.
- Opioid use can also lead to tolerance, dependence, or misuse, potentially resulting in opioid use disorder.
- It is crucial for patients to discuss the potential side effects of these medications with their healthcare providers to make informed decisions about their treatment options.
- type-2-diabetes and ulcerative colitis are chronic-medical-conditions that may also require various therapies and treatments for management.
- In addition to neuropathic pain, diabetes management may involve careful nutrition, fitness-and-exercise, and skin-care routines to prevent complications like eye-health issues, hearing loss, and skin-conditions.
- Depression, a common mental-health issue, is also a medical-condition that often co-occurs with neuropathies, diabetes, or chronic-kidney-disease.
- Migraines, rheumatoid-arthritis, and other neurological-disorders can cause chronic pain and may require multiple therapies and treatments for management.
- Workplace-wellness programs can help employees with chronic-diseases like COPD, asthma, and depression by promoting health-and-wellness, encouraging fitness-and-exercise, and providing resources for mental-health support.
- Nutrition, fitness, mental-health support, and skin-care are essential components of overall health and wellness, impacting not only chronic-diseases like diabetes, neuropathies, and Alzheimer's but also general eye-health, hearing, and skin-conditions.
- Side effects of therapies and treatments for chronic-diseases like neuropathies, diabetes, or Alzheimer's can also affect other aspects of a patient's health, such as hearing or skin.
- Many neuropathic pain patients may also experience depression or other mental-health concerns, highlighting the importance of integrating mental-health care into chronic-disease management plans.
- AQ, a predictive model that is extensively used for primary care, can help healthcare providers to identify and manage patients with chronic-disease risks, including neuropathies, diabetes, and depression.
- Comprehensive chronic-disease management plans should be individualized to address the unique needs of each patient, taking into account potential side effects of therapies, the risk of other chronic-diseases like chronic-kidney-disease, and overall health-and-wellness goals.
