When Is Gabapentin Not The Best Choice: Gabapentin Alternatives for Neuropathic Pain

Living with neuropathic pain can be draining physically and emotionally. Many individuals start their treatment regimen with gabapentin and expect that they will receive relief with its use, but find that they do not see any results or have side effects that impact their ability to function in their daily lives. If you are experiencing this, you are not alone.

This guide was developed for individuals who either cannot tolerate gabapentin, who did not receive any significant relief from it, or have medical or interaction issues that make it difficult to continue using gabapentin.

Prior to exploring gabapentin alternatives, it is important to note that gabapentin should not be abruptly stopped. Medication changes should be supervised by a healthcare professional who can assist you with both tapering your current medication and monitoring how you are doing during the process [1].

Quick Answers: What Can I Take Instead of Gabapentin?

There are several categories of treatments that clinicians typically consider to replace gabapentin. Commonly prescribed options include:

• Alternative Medications: Such as pregabalin (oral), certain antidepressant options — most commonly duloxetine (oral) or amitriptyline (oral), and anticonvulsants based on your diagnosis [2].
• Localized Treatments: These include topical agents like lidocaine (patch, gel, cream) and capsaicin (cream, patch) products [3].
• Non-Drug Treatments: Physical therapy, mindfulness (the practice of intentionally focusing on the present moment with non-judgmental awareness of your thoughts, feelings, bodily sensations, and surroundings), and behavioral therapies (CBT), which are often combined to help you function better and enhance your quality of life [4].

The specific type of neuropathic pain, such as diabetic neuropathy, post-herpetic neuralgia after shingles, or trigeminal neuralgia, along with your overall health history, will determine what medication is the best fit for you.

When Is Gabapentin Not Appropriate?

Gabapentin does not work for everyone, and there are many reasons why someone may not have a good experience.

• Insufficient Relief: Some people find they have gone through a sufficient trial without experiencing pain relief.
• Side Effects: Others experience too many side effects, including sedation, dizziness, cognitive symptoms (related to knowledge and understanding), fog, or swelling [5].
• Health Factors: Dosing complexities can be difficult for individuals with kidney issues, while others take numerous medications, increasing their risk of interactions [1].
• Substance Use History: Those who have a history of substance abuse should also exercise caution when considering using gabapentin.

Gabapentin Alternatives (Prescription Options)

Pregabalin (Lyrica) – The most similar choice to gabapentin

Pregabalin is often the first-line alternative as it is within the same class of medications and works on the same nerve pathways. Clinical evidence suggests that pregabalin may be absorbed and dosed more reliably for some patients and may help improve sleep disruption [6]. Common side effects include sedation, dizziness, and swelling. It is imperative that patients taking pregabalin with other central nervous system (CNS) medications be monitored carefully.

SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors)

Duloxetine and Venlafaxine (oral) are antidepressants that also help to regulate pain signaling [2]. Duloxetine is most commonly prescribed for nerve pain, especially for those who also suffer from a co-occurring mental health disorder, such as depression or anxiety. SNRIs can assist with regulating sensation and mood levels [2]. Side effects may include nausea, headaches, changes in sleep patterns, and changes in blood pressure.

Tricyclic Antidepressants

Older classes of antidepressant medications, such as Amitriptyline, Nortriptyline, and Desipramine, have an established history of effectively treating nerve pain. These can help patients improve their restful sleep [5]. However, trade-offs exist, such as dry mouth, constipation, and sedation due to anticholinergic side effects.

Localized and Condition-Specific Options

Non-Medication Options for Localized Nerve Pain

Topical lidocaine patches and gels are common for localized nerve pain. These are considered safer alternatives as the drugs do not affect the entire body but rather only the area where the medication is applied [3]. Capsaicin may provide symptomatic relief, although the initial burning sensation is uncomfortable.

Condition-Specific Anticonvulsants

Certain anticonvulsants are used for specific conditions, like carbamazepine (oral) and oxcarbazepine (oral) for trigeminal neuralgia. Oral topiramate is generally reserved for a small number of patients due to cognitive side effects [1].

Opioid-Adjunct Alternatives

Tramadol (oral) is an option but is not typically a first-line choice due to risks of tolerance, dependence, and interactions. It is usually used for short-term or closely monitored situations.

Non-Medication Options for Neuropathic Pain

• Physical Therapy: Focuses on improving mobility, strength, posture, and moving nerves properly.
• CBT: Cognitive behavioral therapy is focused on identifying patterns and modifying unhelpful behaviors and thought processes associated with pain [4].
• DBT: Dialectical behavioral therapy (a form of talk therapy that helps people manage intense emotions and behaviors) is designed to teach people how to manage their intense emotions and behaviors.
• Sleep Hygiene: Having healthy habits, known as sleep hygiene (practices and habits that promote healthy, restful sleep), is highly integral in how we perceive pain [4].
