Epleptin is gabapentin, supplied as 100 mg, 300 mg and 400 mg capsules. Despite the name, most people who take it are not being treated for epilepsy. Its commonest use in South Africa is nerve pain — the burning, shooting or electric-shock pain of diabetic neuropathy, shingles and trapped nerves.
What is Epleptin?
Epleptin contains gabapentin. The South African Medicine Price Registry lists three capsule strengths, all Schedule 3 (prescription-only):
| Product | Form | Strength |
|---|---|---|
| Epleptin | Capsule | Gabapentin 100 mg |
| Epleptin | Capsule | Gabapentin 300 mg |
| Epleptin | Capsule | Gabapentin 400 mg |
The name is a fossil of how the medicine was first developed. Gabapentin was designed as an anti-epileptic, and it does work in epilepsy — but its usefulness in nerve pain turned out to be the larger part of its role.
It works by binding to a subunit of calcium channels on overactive nerve endings, which reduces the release of the signalling chemicals that carry pain messages. In practical terms, it quietens nerves that are firing when they should not be. That is why it works for pain caused by nerve damage and does very little for ordinary pain from an injury or inflammation.
The three strengths exist because gabapentin is titrated — started low and increased in steps over days or weeks until it works or until side effects stop the climb. Someone might start on 100 mg at night and end up on several hundred milligrams three times a day. A change in your strength is usually the plan working, not a change of medicine.
What is Epleptin commonly used for?
- Diabetic nerve pain — burning, tingling or shooting pain in the feet and hands. This is one of its most common uses in South Africa.
- Post-herpetic neuralgia — pain persisting after shingles.
- Sciatica and nerve-root pain from a trapped or compressed nerve.
- Nerve pain after surgery, injury or amputation.
- Epilepsy, as add-on treatment for partial seizures.
- Restless legs syndrome, in some prescribing.
- Nerve pain associated with HIV, chemotherapy or spinal problems.
- Occasionally for migraine prevention, anxiety or hot flushes, though these are secondary uses with weaker evidence.
Two practical points matter more than the list.
It is a regular medicine, not a rescue one. Gabapentin has to be taken consistently. It does not work like a painkiller taken when pain strikes, and judging it after two days will make it look useless.
It takes weeks to show its full effect, because of the titration. Many people give up during the first week, when the drowsiness has arrived but the benefit has not.
How Epleptin fits into this medicine category
| Group | Examples | Where it fits |
|---|---|---|
| Gabapentinoids | Gabapentin (Epleptin), pregabalin | Nerve pain, some seizure types |
| Tricyclics | Amitriptyline (Trepiline) | Nerve pain at low dose; depression at higher dose |
| SNRIs | Duloxetine, venlafaxine | Nerve pain and mood together |
| Anti-epileptics | Carbamazepine, sodium valproate, lamotrigine | Seizure control; carbamazepine also for trigeminal neuralgia |
| Sleep agents | Zolpidem and related medicines | Short-term insomnia |
| Ordinary painkillers | Paracetamol, anti-inflammatories | Poorly effective for nerve pain specifically |
That last row explains why gabapentin gets prescribed at all: nerve pain responds badly to the medicines most people reach for first. See the mental health and neurology medicines hub.
What to check before using Epleptin
Tell your doctor or pharmacist if you:
- Have kidney disease or reduced kidney function. This is the most important check. Gabapentin is cleared almost entirely by the kidneys, and the dose must be reduced when they are not working well — otherwise it accumulates and causes marked drowsiness and confusion.
- Take opioid painkillers — tramadol, codeine, morphine. Combining opioids with gabapentin raises the risk of dangerously slowed breathing, and this combination has been the subject of specific safety warnings.
- Take other sedating medicines — benzodiazepines, sleeping tablets, sedating antihistamines.
- Have breathing problems, especially COPD or sleep apnoea, or are elderly — both increase the risk of respiratory depression.
- Have a history of substance misuse. Gabapentin is misused in some settings and can cause dependence.
- Have depression or a history of self-harm. Anti-epileptic medicines carry a small increased risk of suicidal thoughts.
- Are pregnant, planning pregnancy or breastfeeding.
- Take antacids containing aluminium or magnesium — separate them from gabapentin by about two hours, as they reduce absorption.
Practical points:
- Do not drink alcohol, at least until you know how it affects you. The sedation is additive.
- Do not drive until you are stable on a dose and know your reaction.
- Take it at evenly spaced times, as prescribed. Gabapentin does not last long in the body.
- Do not stop suddenly. Stopping abruptly can trigger withdrawal — anxiety, insomnia, nausea, sweating, pain — and in someone with epilepsy it can provoke seizures. Any reduction should be gradual and planned.
Follow the prescribed titration exactly. This page does not set doses.
Possible cautions and when to ask a pharmacist or doctor
The commonest effects, particularly early on, are drowsiness, dizziness, unsteadiness, blurred vision, swollen ankles and weight gain. Drowsiness and dizziness usually improve over one to two weeks, which is exactly why the dose is built up slowly rather than started high.
Seek medical advice promptly for:
- Marked confusion, severe drowsiness or difficulty staying awake — particularly if you also take an opioid or a sedative.
- Slow or shallow breathing. Get emergency help.
- New or worsening depression, agitation, or thoughts of self-harm.
- A widespread rash, blistering, or a rash with fever and swollen glands — rare but serious reactions have been reported. Get emergency help.
- Swelling of the face, lips or tongue, or difficulty breathing.
Contact your doctor if:
- Pain is not improving once you reach the target dose. Gabapentin does not work for everyone, and there are alternatives.
- Side effects are not settling after the first couple of weeks.
- You find yourself taking more than prescribed, or wanting to.
- Seizure control changes, if you take it for epilepsy.
- Your kidney function changes, or you are started on a new medicine by another prescriber.

Frequently asked questions
What is Epleptin 300 mg used for? Most commonly nerve pain — diabetic neuropathy, pain after shingles, sciatica and other nerve-damage pain. It is also used as add-on treatment for epilepsy.
What is Epleptin 100 mg used for? The same conditions. The 100 mg capsule is generally a starting or step-up strength while the dose is being built up.
Do I have epilepsy if I’ve been prescribed this? No. Despite the name, most prescriptions in South Africa are for nerve pain, not seizures.
How long before it works? Days to weeks, because the dose is increased gradually. Judge it once you reach the target dose, not in the first few days.
Is it a painkiller? Not in the ordinary sense. It calms overactive nerves and must be taken regularly — it does not relieve pain on demand.
Can I stop when the pain settles? Not abruptly. Stopping suddenly can cause withdrawal symptoms and, in epilepsy, seizures. Ask your doctor to plan a gradual reduction.
Can I drink alcohol on it? Best avoided. Alcohol adds to the drowsiness and dizziness.
Is it addictive? It can cause dependence, and it is misused in some settings. Take only the prescribed dose and tell your doctor if you feel you need more.
