Gabastone Nt. is used for neuropathic (nerve) pain such as diabetic neuropathy, post-herpetic neuralgia, radiculopathy/sciatica-related neuropathic pain, and other chronic nerve pain conditions as prescribed.
Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Gabastone Nt. contains Gabapentin (400mg) + Nortriptyline (10mg/gm). It belongs to the Gabapentinoid (antiepileptic) + Tricyclic antidepressant (TCA) class of medicines.
Gabapentin reduces abnormal nerve signalling by binding to the alpha-2-delta subunit of voltage-gated calcium channels in the CNS, thereby decreasing release of excitatory neurotransmitters. Nortriptyline (a tricyclic antidepressant) increases levels of norepinephrine and serotonin in pain pathways and also modulates sodium channels, enhancing pain control.
Take by mouth exactly as prescribed, usually once daily at night or in divided doses. Can be taken with or without food; taking after food may reduce stomach upset. Swallow whole with water; do not stop suddenly without medical advice.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.
An overdose of this medicine can cause deep drowsiness, confusion, unsteadiness and slowed breathing, especially with an opioid or alcohol. It can cause fits, dangerous heart rhythm disturbance and coma, and is particularly dangerous with the older tricyclic medicines. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
Most side effects of Gabastone Nt. are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.
| Pregnancy | Use with caution / Consult doctor (use only if benefit outweighs risk) |
|---|---|
| Breastfeeding | Consult your doctor before using this while breastfeeding. |
| Alcohol | Avoid (increases dizziness/drowsiness and risk of breathing problems) |
| Driving | Do not drive or operate machinery while taking this medicine. |
| Kidney | Consult your doctor if you have kidney disease. |
| Liver | Consult your doctor if you have liver disease. |
| Habit forming | No |
May cause sleepiness/dizziness—avoid driving or operating machinery until you know its effects. Do not stop abruptly (risk of withdrawal symptoms and worsening pain/seizures with gabapentin). Use with caution in elderly, kidney disease (dose adjustment for gabapentin), glaucoma, urinary retention/prostate enlargement, heart disease/arrhythmias, and history of bipolar disorder or suicidal thoughts (monitor mood/behavior). Nortriptyline can cause orthostatic hypotension and may worsen angle-closure glaucoma. Seek urgent help for suicidal ideation, severe rash/allergy, breathing difficulty, or severe swelling.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Must not be combined with a monoamine oxidase inhibitor, or started within the gap your doctor specifies after one.
Alcohol and other CNS depressants (opioids, benzodiazepines, sedating antihistamines) increase drowsiness/respiratory depression; MAO inhibitors (contraindicated with nortriptyline); SSRIs/SNRIs and other serotonergic drugs (risk of serotonin syndrome); medicines that prolong QT interval/antiarrhythmics (additive cardiac risk with nortriptyline); anticholinergics (increased dry mouth/constipation/urinary retention); gabapentin absorption reduced by aluminum/magnesium antacids (separate by at least 2 hours).
Store below 25°C in a cool, dry place, protected from light and moisture. Keep out of reach of children.
Take the larger part of the dose at night if drowsiness is a problem. Rise slowly from sitting or lying, especially in the first weeks. Keep your review appointment so the dose can be adjusted to the lowest that controls your pain. Give it a fair trial of several weeks, and keep your review appointments. Take it at the same time each day — at night if it makes you drowsy, in the morning if it disturbs sleep. Talking therapy alongside medicine works better than either alone for most people.
