Nervillin NT tablets 30s

What Is NERVILLIN NT?

Nervillin NT is a combination of two medicines that both help reduce nerve pain through different pathways. Nortriptyline is a tricyclic antidepressant (TCA) that, at low doses used in pain management, modifies how the brain perceives pain signals, it doesn't work as an antidepressant at these doses but rather 'turns down the volume' on pain signals travelling up to the brain.

Gabapentin reduces pain by calming overactive calcium channels in damaged nerve fibres that are sending excessive pain signals. Together, they provide a complementary, synergistic approach to nerve pain management, often achieving better pain control with lower doses of each component than would be needed if used alone.

What Is It Used For?

Nervillin NT is prescribed for neuropathic pain, the often difficult-to-treat pain caused by damaged or dysfunctional nerves. This includes burning, shooting, stabbing, tingling, or electric shock-like sensations, commonly affecting the hands and feet in conditions such as diabetic peripheral neuropathy, post-herpetic neuralgia (pain after shingles), fibromyalgia, and chronic musculoskeletal pain syndromes with a neuropathic component.

The bedtime dosing that is often used for this combination also benefits patients whose nerve pain is worst at night, as the sedative properties of both medicines can improve sleep quality alongside pain control.

Typical Dosing

Often taken at bedtime to take advantage of the sedating effects for night pain and sleep improvement. Your doctor may prescribe once or twice daily, follow their specific instructions.

Start Low, Go Slow

Nortriptyline is usually started at a very low dose and increased gradually to minimise side effects like dry mouth and dizziness.

With or Without Food

Can be taken with or without food. If stomach discomfort occurs, take with food.

Do Not Stop Suddenly

Do not stop Nervillin NT abruptly, gradually taper under medical guidance, especially the Nortriptyline component.

Missed Dose

Take as soon as remembered unless close to the next dose. Never double up.

Common Side Effects

·       Drowsiness (Nortriptyline + Gabapentin, often beneficial for night-time use)

·       Dry mouth (Nortriptyline)

·       Dizziness or unsteadiness (Gabapentin)

·       Constipation (Nortriptyline)

·       Blurred vision (Nortriptyline)

·       Weight gain

Uncommon Side Effects

·       Urinary retention (Nortriptyline, especially in elderly men)

·       Memory difficulties

·       Swollen ankles

·       Increased appetite

Serious Side Effects, Seek Immediate Medical Attention

·       QT prolongation and cardiac arrhythmias (Nortriptyline, avoid in patients with heart disease or on QT-prolonging drugs)

·       Suicidal thoughts or worsening depression (report immediately)

·       Narrow-angle glaucoma precipitation (Nortriptyline)

·       Respiratory depression with opioids or sedatives

·       Severe anticholinergic toxicity in overdose

·       CARDIAC: Nortriptyline prolongs the QT interval, avoid in patients with heart disease, arrhythmias, or those on other QT-prolonging medicines.

·       ELDERLY: Particularly high risk of falls, urinary retention, constipation, and confusion from the anticholinergic effects of Nortriptyline.

·       SUICIDAL THOUGHTS: Report any worsening depression, mood changes, or thoughts of self-harm to your doctor immediately.

·       DRIVING: Both components cause drowsiness, do not drive or operate machinery, especially when starting or increasing the dose.

·       ALCOHOL: Avoid completely, dramatically worsens sedation.

·       MONOAMINE OXIDASE INHIBITORS (MAOIs): A potentially fatal interaction, allow at least 14 days after stopping an MAOI before starting Nervillin NT.

·       OVERDOSE: TCAs are dangerous in overdose, store safely away from children and anyone at risk of self-harm.

MAO inhibitors: POTENTIALLY FATAL, wait at least 14 days after stopping MAOIs before starting Nortriptyline.

QT-prolonging drugs (amiodarone, haloperidol, chloroquine, azithromycin): Additive QT prolongation, avoid.

Anticholinergic drugs (antihistamines, bladder relaxants, antiparkinson drugs): Additive anticholinergic effects (dry mouth, urinary retention, confusion).

CNS depressants (benzodiazepines, opioids, alcohol): Additive sedation, potentially dangerous.

SSRIs (fluoxetine, paroxetine): Can increase Nortriptyline levels, risk of toxicity.

Antihypertensives: Nortriptyline may reduce or enhance antihypertensive effect.

Antacids: Reduce Gabapentin absorption, separate by 2 hours.

·       Store below 25°C in a cool, dry place.

·       Protect from moisture and light.

·       Keep in original packaging.

·       Keep out of reach of children, particularly important given TCA overdose risk.

Nervillin NT is a prescription-only medicine (POM) in Kenya. The Nortriptyline component is a psychoactive drug requiring a valid prescription. Available at Pharmily with a valid prescription from a physician, neurologist, psychiatrist, or pain specialist.

Nervillin NT is a TCA + Gabapentin combination, an evidence-based approach to neuropathic pain utilising synergistic mechanisms with potentially lower doses of each component. The QT prolongation risk of Nortriptyline is the most critical safety screen, check for concurrent QT-prolonging medications (chloroquine, amiodarone, haloperidol, azithromycin, all common in Kenya).

The MAOI interaction is absolutely contraindicated and potentially fatal, screen medication history carefully. Elderly patients require particular vigilance for anticholinergic burden: urinary retention, constipation, confusion, and fall risk from orthostatic hypotension are major concerns.

TCA overdose danger means the product should be stored safely, counsel carers and family members in households with children or vulnerable individuals. Renal dose adjustment for Gabapentin is essential, check eGFR in diabetic patients who are the primary user group. Bedtime dosing counselling should be explicit, this is often the most practical and well-tolerated regimen.

Q1: What is Nervillin NT used for?

A: Nervillin NT is used to treat neuropathic (nerve) pain, the burning, shooting, or tingling pain caused by nerve damage from diabetes, shingles, fibromyalgia, or other conditions.

Q2: Why does Nervillin NT contain an antidepressant (Nortriptyline)?

A: At low doses used in pain management, Nortriptyline does not act as an antidepressant. Instead, it modifies the way your brain processes pain signals, effectively reducing the pain you feel. This is separate from its antidepressant effects.

Q3: Why is Nervillin NT often taken at bedtime?

A: Both medicines cause drowsiness, which can be beneficial at night, helping you sleep while also relieving night-time nerve pain. Your doctor will decide the best timing for your specific situation.

Q4: Is it safe to drive while taking Nervillin NT?

A: Not initially. Both Nortriptyline and Gabapentin cause drowsiness and dizziness. Do not drive until you know how this medicine affects you, usually after 1–2 weeks of the maintenance dose.
