Has anybody ever tried Zonisamide for nerve pain?
My doctor prescribed Zonisamide for nerve pain but I can’t find any evidence that it works for that. I have tried gaba and Dulox… but neither had any effect. My pain is nerve pain in the pelvic region, specifically the pudendal nerve.

Zonisamide is a medication primarily approved to treat seizures, but it’s sometimes used off-label for certain types of nerve pain.
How it works for nerve pain
Zonisamide affects electrical activity in the nervous system by:
• Blocking sodium and calcium channels
• Modulating neurotransmitters
These actions can reduce abnormal nerve firing, which is a key cause of neuropathic pain.
Is it commonly used?
Not really. For nerve pain, doctors usually try first:
• Gabapentin
• Pregabalin
• Duloxetine
• Amitriptyline
Zonisamide tends to be considered when:
• First-line treatments don’t work
• Side effects from other meds are an issue
• A specialist (like a neurologist or pain doctor) is involved
Evidence for nerve pain
• Research is limited and mixed
• Some small studies suggest benefit in conditions like diabetic neuropathy
• It’s not widely recommended in major guidelines
Potential side effects
Common:
• Drowsiness or dizziness
• Loss of appetite / weight loss
• Trouble concentrating
Less common but important:
• Kidney stones
• Metabolic acidosis
• Heat intolerance (reduced sweating)
Bottom line
Zonisamide can help nerve pain in some cases, but it’s not a standard first-choice medication. It’s usually considered a backup option when more established treatments don’t work.

@sash I was on Zonegran 20 years ago, but it did not help me. It also caused a rash after a while. I started out on gabapentin which was helpful but started causing memory problems. I am now on Lyrica, which does help me with nerve pain.
