December is my month of regeneration and being present in the moment. It's a time when I slow down, listen to my body, and give my nervous system some quiet. That's why I've been here less often and spending less time at the computer, but know this — I'm still thinking about you.
About you, about our shared battles with the trigeminal nerve, about the daily invisible fight that each of us wages in silence.
In January, I'll also be here less — it's still a time for rebuilding strength. But starting in February, I'll be back with a head full of ideas, topics, and energy, ready again to support, explain, organize knowledge, and put words where pain so often takes them away.
Because living with trigeminal neuralgia is not simply "dealing with pain."
It's more like an epic campaign where every day we face an invisible, unpredictable, and merciless opponent — a bit like fantasy game heroes traveling through a land full of traps, where every step requires strategy, patience, and enormous courage. And medications, procedures, decisions, and small steps backward or forward are our spells, shields, and swords — yes, I spent some of my free time on the next season of Stranger Things. ;)
And that is exactly what I want to write about today — one of those "tools": antiepileptic and antidepressant medications.
In brief: how they work, how to take them, how to minimize side effects, and why discontinuing them is a process that requires calm, humility, and time. My friend Asia helped me prepare this post — someone incredibly aware and mindful, who was fortunate to find physicians with whom she found a real flow. Because sometimes in treatment, it's not just about knowledge and procedures, but about meeting the right person — someone who listens, explains, and guides with sensitivity.
In this fight, you don't win by rushing.
You win with wisdom.
Medications used in trigeminal neuralgia
In treating trigeminal neuralgia, antiepileptic and antidepressant medications are very commonly used. Although their names may sound alarming, one thing needs to be said clearly:
These are not medications "for epilepsy" or "for depression" — they are for neuropathic pain.
How do these medications work?
Medications such as carbamazepine, oxcarbazepine, gabapentin, pregabalin, and the antidepressant duloxetine:
- Stabilize overreactive neurons
- Reduce the "firing" of pain impulses
- Act as neuromodulators, not as acute painkillers
- That is why they don't work like a pain pill and must be taken regularly, at consistent times
What you must NOT do
- Take medications "as needed" sporadically
- Increase doses when it hurts and decrease them when it doesn't
- Stop medications abruptly — even if it seems like "they're not working"
- Discontinue on your own, without a plan
Sudden changes are a shock to the nervous system and can lead to:
- Severe pain recurrence
- Dizziness, night sweats, anxiety
- Withdrawal syndrome comparable to alcohol or drug withdrawal
How to take medications correctly
- Regularly, at the same times each day
- At the dose established with your physician
- With patience — effects often appear after days or weeks
- While monitoring bloodwork (e.g., complete blood count, electrolytes)
Remember:
Starting medications is usually easier.
Coming off them is much harder.
How to minimize side effects
- Increase doses slowly
- Don't introduce multiple changes at once
- Observe your body (drowsiness, dizziness, "brain fog" often diminish over time)
- Drink adequate amounts of water
- Maintain good sleep and daily routine
- Avoid alcohol and grapefruit (carbamazepine and oxcarbazepine — grapefruit significantly raises their blood levels, increasing the risk of drowsiness, dizziness, nausea, and hyponatremia/possible overdose symptoms; gabapentin and pregabalin — the interaction is mild, but grapefruit may slightly worsen "brain fog")
- For nausea — take medications with food
Diet supporting the nervous system (very important!)
Medications are one thing, but the body needs the building blocks to repair itself.
Vitamins and nutrients supporting nerve health:
- Vitamins B1, B6, B12 (meat, eggs, nuts, whole grains) — support myelination and nerve impulse conduction
- Omega-3 fatty acids (fatty fish, optionally flaxseed) — have anti-inflammatory effects and may reduce neuropathic pain
- Antioxidants: vitamins C, E, zinc, selenium
- Magnesium — supports sleep, reduces tension and cramping
Sodium and electrolytes — a crucial topic
Oxcarbazepine and carbamazepine can cause hyponatremia (low sodium levels in the blood) because they affect sodium regulation in the kidneys.
- Normal sodium range: 135–145 mmol/L
- Monitoring: every 3–6 months (especially in patients over 65)
How to support yourself with diet:
- Table salt (in reasonable amounts)
- Cheese, cured meats (personally, I do not eat commercially processed meats. If such products appear in my diet, they are homemade)
- Fermented foods
- Electrolytes / sugar-free isotonic drinks
- Approximately: 2–3 g of sodium per day, unless your physician advises otherwise
Symptoms of hyponatremia:
Fatigue, headaches, nausea, confusion — report these to your doctor.
Sugar and glucose
Sugar does not directly interact with these medications. However, an excess of simple carbohydrates:
- Intensifies inflammation
- Worsens "brain fog"
- May increase fatigue with gabapentinoids
Recommendations:
- Limit refined sugar (less than 25 g/day)
- Choose a minimally processed diet
- Focus on vegetables, fruits, protein, whole grains
- For individuals with diabetes: note that duloxetine may slightly affect blood glucose levels
How to SAFELY taper medications
Tapering is a process. A long one. A careful one. And always individualized.
General principles:
- Never abruptly
- Always gradually
- Ideally after pain stabilization (e.g., several weeks after a procedure)
Example schedule (always subject to modification):
- Reduce the dose by 1/4 tablet
- One week of observation
- If everything is fine — another week of "consolidation"
- Only then the next reduction
If pain increases — step back, return to the previous dose, and slow the pace.
This is not failure. This is wise regulation.
Important considerations
With painful trigeminal neuropathy:
- It is not always possible to discontinue all medications
- The goal is to reduce doses, not a heroic "zero"
- At some point the nerve says: STOP
- And then... we listen
This condition teaches:
- Patience
- Mindfulness
- Respect for your own nervous system
Medications are a tool, not an enemy.
And calm, wisdom, and slowness are the best strategy in trigeminal neuralgia.

Frequently Asked Questions
What is trigeminal neuralgia?
Trigeminal neuralgia is a chronic facial pain condition. It manifests as sudden, severe, usually one-sided pain attacks — often described as an electric shock. A single attack typically lasts from a few seconds to about two minutes.
What is the difference between neuralgia and neuropathy?
In simple terms: neuralgia primarily involves paroxysmal pain along a nerve, usually without loss of sensation. Neuropathy involves nerve damage that more often causes constant pain along with numbness and sensory loss.
Do regular painkillers help with neuropathic pain?
Usually not. Neuropathic pain responds poorly to paracetamol or anti-inflammatory drugs. Instead, medications that act on nerves are used, such as anticonvulsants like carbamazepine.
How does carbamazepine work for trigeminal neuralgia?
Carbamazepine is the first-line medication for trigeminal neuralgia. In a large proportion of patients, it provides effective pain control. It requires gradual dose adjustment and medical supervision.
What is the difference between gabapentin and pregabalin?
Both are anticonvulsant medications used for neuropathic pain. They differ in absorption and dosing characteristics. The choice and dosage should be determined by a physician.
