When a patient hears that antidepressants have been added to their treatment — alongside anticonvulsants — it often causes surprise, and sometimes even concern.
A thought may appear:
"Does my doctor think this pain is all in my head?"
The answer is: absolutely not.
Prescribing antidepressants does not mean the pain is "psychological." Their role in neuropathic pain is based on how they act on the nervous system.
How They Work for Pain
Antidepressants are primarily known for treating depression and anxiety. But certain ones (e.g., amitriptyline, duloxetine, venlafaxine) work in an entirely different way when it comes to pain.
In our nervous system, there are specialized pathways that "inhibit" pain signals traveling from nerves to the brain. In neuropathic pain, these mechanisms often fail — nerves become hyperexcitable and transmit pain signals even without actual tissue damage.
Antidepressants strengthen the action of two neurotransmitters: serotonin and noradrenaline. These are responsible for the "inhibitory" function in the nervous system. The result? The brain receives a weaker pain signal, and the patient experiences real relief.
An Analogy
Think of it like an electrical system: nerves conduct impulses like wires. In neuralgia or other neuropathies, the wires become "hypersensitive" — they send too many impulses.
Antidepressants do not "cut the power," but rather strengthen the circuit breakers that reduce the intensity of those signals. As a result, they do not reach the brain as strongly.
What the Patient Actually Feels
- fewer pain attacks,
- lower intensity,
- shorter duration of episodes.
The Dual Benefit
Chronic pain itself affects mental health. Months or years of living with pain very often lead to:
- chronic stress,
- sleep disturbances,
- anxiety,
- depression.
Antidepressants therefore work on two fronts:
- They reduce neuropathic pain itself.
- They alleviate the psychological consequences of living with pain.
Thanks to antidepressants, a patient can function better on a daily basis — sleep more easily, regain some energy, and reduce the emotional tension that further amplifies the perception of pain.

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.
Which doctor should I see for facial pain?
First, see a neurologist. If surgery is being considered, a neurosurgeon. If a dental cause is suspected, it is also worth ruling it out with a dentist.
Can trigeminal neuralgia be cured?
In many people, pain can be effectively controlled with medications or procedures, and MVD provides the most durable results in eligible patients. The course varies — with periods of remission and relapse. Decisions are made together with your doctor.
