Nerve Pain Medications

Treating Nerve Pain

Nerve pain (neuropathic pain) doesn't respond well to typical pain medications like NSAIDs or acetaminophen. Instead, medications that calm overactive nerves work better. Several classes of medications are used, often requiring trial and error to find the best option.¹

First-Line Medications²

Gabapentinoids

• Gabapentin (Neurontin)
• Pregabalin (Lyrica)
• Good evidence for many neuropathic conditions
• Main side effects: drowsiness, dizziness

SNRIs

• Duloxetine (Cymbalta)—FDA approved for several pain conditions
• Venlafaxine (Effexor)
• Work on both pain and mood pathways

Tricyclic Antidepressants

• Amitriptyline
• Nortriptyline
• Used at lower doses than for depression
• Often taken at bedtime

Second-Line Options³

Topical Treatments

• Lidocaine patches or cream
• Capsaicin patches (high dose)
• Capsaicin cream (OTC)
• Good for localized pain

Other Options

• Tramadol (weak opioid properties)
• Strong opioids (generally last resort)
• Carbamazepine (for trigeminal neuralgia)

What to Expect

• May need to try multiple medications
• Full effect takes weeks
• Goal is often 30-50% pain reduction
• Complete relief uncommon
• Side effects often improve with time

Medication Principles

• Start low, go slow
• Give adequate trial (4-8 weeks)
• May combine medications
• Don't stop suddenly
• Communicate with your doctor

Combination Therapy

• Sometimes combining classes works better
• Example: gabapentinoid + antidepressant
• Oral + topical
• Must watch for interactions

Why Standard Pain Meds Don't Work

• Nerve pain has different mechanisms
• Damaged nerves send abnormal signals
• Need medications that calm nerve firing
• NSAIDs don't address nerve dysfunction

Non-Medication Options

• TENS unit
• Physical therapy
• Spinal cord stimulation
• Pain psychology
• Often combined with medications
