Uses

  • Nerve pain (neuropathic pain) – diabetic neuropathy, sciatica, pain after shingles (post-herpetic neuralgia).
  • Epilepsy – focal seizures, alone or with other anti-epileptics.
  • Restless legs syndrome and some chronic pain conditions, on a doctor's advice.

How to take it

Take it exactly as prescribed, usually 3 times a day spaced evenly (morning, afternoon and bedtime), with or without food. Swallow the capsule whole with water; do not open or chew it. Your doctor will start with a low dose – often 300 mg at night – and increase over several days to weeks until the pain or seizures are controlled. Gabapentin can make you drowsy and dizzy, especially at first, so avoid driving until you know how it affects you. For nerve pain it is continued for months after the pain settles; for epilepsy, usually for years. Do not stop suddenly – stopping abruptly can cause seizures and withdrawal symptoms such as anxiety, sweating and poor sleep; the dose is reduced over at least a week.

Side effects

Common

  • Drowsiness, tiredness or dizziness – usually ease within a week or two.
  • Unsteadiness, poor coordination.
  • Weight gain, increased appetite.
  • Swollen hands, feet or ankles.
  • Blurred vision, dry mouth.

Serious

Stop and get medical help urgently if you notice any of these.

  • Thoughts of harming yourself, or new depression or agitation – get help immediately.
  • Trouble breathing, especially with opioids or in lung disease – emergency.
  • Severe rash with fever, swollen glands or yellow skin (serious drug reaction).
  • Hallucinations or severe confusion.

Safety information

Alcohol

Avoid alcohol. It greatly increases drowsiness and dizziness with gabapentin.

Pregnancy

Tell your doctor if you are pregnant or planning pregnancy. Gabapentin is used in pregnancy only when the benefit is clear, with folic acid. It passes into breast milk in small amounts.

Kidney problems

Gabapentin is removed by the kidneys, so the dose must be reduced if kidney function is low. Your doctor will check your eGFR.

Liver problems

No dose change is needed for liver disease.

Children

Used for epilepsy in children over 6 under a specialist; not used for nerve pain in children.

Missed dose

Take it as soon as you remember unless the next dose is due within 2 hours – then skip it. Never take two doses together.

Interactions

  • Opioid painkillers (tramadol, codeine, morphine) – dangerous drowsiness and slowed breathing.
  • Sleeping pills, alprazolam, clonazepam, sedating antihistamines – added sedation.
  • Antacids containing aluminium or magnesium (Digene, Gelusil) – reduce absorption; take gabapentin at least 2 hours after.
  • Antidepressants (amitriptyline, duloxetine) and antipsychotics – more drowsiness; often combined for pain, but tell your doctor.
  • Alcohol – avoid.

Frequently asked questions

What is Gabapin 300 used for?

Gabapin 300 contains gabapentin 300 mg. It is used for nerve pain – diabetic neuropathy, sciatica, pain after shingles – and for focal seizures in epilepsy. It calms over-active nerve signals.

Gabapin 300 vs Gabapin NT – what is the difference?

Gabapin 300 is gabapentin alone. Gabapin NT adds nortriptyline, an antidepressant that also eases nerve pain, and is used when gabapentin alone is not enough. Your doctor chooses based on your pain and sleep.

How long does Gabapin take to work for nerve pain?

Some relief may start within a week, but the full effect takes a few weeks as the dose is gradually increased. Do not stop early because it seems slow.

Can I take Gabapin 300 with alcohol?

Avoid it. Alcohol with gabapentin causes marked drowsiness, dizziness and poor coordination, and increases the risk of falls.

Does gabapentin cause weight gain?

It can increase appetite and cause some weight gain and fluid retention in some people. Tell your doctor if this becomes a problem.

Is Gabantin 300 habit-forming?

Gabapentin is not an opioid, but misuse and dependence can occur, and stopping suddenly causes withdrawal symptoms. Take only the prescribed dose and taper off under your doctor's guidance.

Gabapentin vs pregabalin (Lyrica) – which is better?

They work the same way. Pregabalin is absorbed more predictably and dosed twice daily; gabapentin is cheaper and dosed three times daily. Both cause drowsiness and weight gain. Your doctor picks based on response and cost.

Is Gabapin 300 safe for kidney patients?

It can be used, but the dose must be reduced according to kidney function because gabapentin is removed by the kidneys. Your doctor will adjust it.

Can I drive while taking Gabapin 300?

Not until you know how it affects you. Gabapentin commonly causes drowsiness and dizziness, especially in the first weeks and after dose increases.
