AIDA medical review | For readers over 30 | Written from a doctor’s practice experience
If you are over 30, you may already know the frustration of pain that paracetamol or ibuprofen barely touches. Nerve pain is different. It feels like burning, electric shocks, pins and needles, or icy heat under the skin. It can wake you at night, make walking difficult, and leave you short-tempered with the people you love. In my Australian practice, patients describe it as “ants crawling along my leg” after shingles, “socks full of broken glass” with diabetic neuropathy, or “a hot wire across my ribs” after surgery. Gabapentin is one of the most useful medicines we have for this type of pain.
Gabapentin is a prescription-only medicine in Australia (Schedule 4). It was originally developed to treat epilepsy, but over the last 25 years it has become a cornerstone for neuropathic pain. It works by calming overactive nerve signals. Unlike opioids, it does not directly block pain receptors; it reduces the abnormal firing of damaged nerves. This makes gabapentin an important option for people who want long-term pain control without opioid dependence.

As with any medicine, gabapentin is not risk-free. It can cause dependence in some people, especially at higher doses, so it must be used exactly as prescribed.
Gabapentin is particularly effective for postherpetic neuralgia (nerve pain after shingles), diabetic peripheral neuropathy, and radicular pain from sciatica or spinal nerve compression. Many patients tell me they can finally sleep through the night because the electric shocks settle down.
Sleep disturbance is one of the most distressing parts of nerve pain. By reducing pain and having a mild sedating effect, gabapentin can help restore a normal sleep cycle. For many people over 50, better sleep means more energy, better mood, and more patience.
NSAIDs such as ibuprofen, diclofenac, and naproxen can irritate the stomach lining, increase blood pressure, and harm the kidneys. Gabapentin does not cause stomach ulcers or kidney injury in the same way. This is a major advantage for people over 40 who already have reflux, gastritis, or high blood pressure.
In Australia, gabapentin is used off-label for menopausal hot flashes (hot flushes), especially in women who cannot take hormone replacement therapy, such as those with a history of breast cancer or blood clots. Studies show gabapentin can reduce both the frequency and intensity of hot flushes. This is not a first-line menopause treatment, but it is a well-recognised option discussed in Australian menopause guidelines.
Because gabapentin is an anticonvulsant, it can be used in people with epilepsy. It may be prescribed alone or with other seizure medicines. If you have a history of seizures, never stop gabapentin suddenly — the dose should be reduced gradually under medical supervision to avoid withdrawal seizures.
Gabapentin is occasionally used off-label for anxiety in children and adolescents, but only by paediatricians or child psychiatrists when standard treatments have not worked. It is not a first-line treatment for childhood anxiety. Parents should not start it without specialist advice, because dosage and monitoring are very different in young people.
Mastitis itself is an infection and inflammation of the breast tissue; it requires medical treatment, usually antibiotics, drainage if there is an abscess, and anti-inflammatory measures. Gabapentin is not a treatment for acute mastitis. However, if mastitis has been treated and a burning or shooting nerve pain persists in the breast or nipple area, gabapentin may be considered for that neuropathic residual pain. This should always be evaluated by a doctor to rule out an ongoing infection or other breast condition.
| Question | Answer |
|---|---|
| Can I take gabapentin if I have a history of seizures? | Yes. Gabapentin is an anticonvulsant and can be appropriate for people with epilepsy. However, the dose must be individualised, and you should never stop it abruptly because sudden withdrawal can trigger seizures. Always follow your neurologist or GP’s tapering plan. |
| Does gabapentin interact with kava? | Yes, there is a potential interaction. Kava can cause sedation and affect the liver. Combined with gabapentin, there may be increased drowsiness, dizziness, and impaired coordination. I strongly recommend avoiding kava while taking gabapentin, especially if you are older or need to drive. If you use kava, tell your doctor. |
| Is gabapentin used for hot flashes in Australia? | Yes, gabapentin is used off-label for hot flashes (commonly called hot flushes in Australia), particularly for menopausal women who cannot use hormone therapy. It is not TGA-approved specifically for hot flushes, but Australian doctors may prescribe it for this purpose based on clinical evidence. |
| Can I take gabapentin if I have gastrointestinal disorders? | Generally yes, and it may be a safer pain option than NSAIDs if you have gastritis, reflux, ulcers, or inflammatory bowel disease. Gabapentin can cause nausea or changes in bowel habits in some people, so start with a low dose, take it with food, and report any worsening GI symptoms to your doctor. |
| Can gabapentin be used for anxiety in children? | It is sometimes used off-label for anxiety in children, but only by specialists. It is not a first-line treatment. Psychological therapy and approved medicines are usually tried first. If a child is struggling with anxiety, see a paediatrician or child psychiatrist rather than starting gabapentin from an adult prescription. |
| Can I take gabapentin with NSAIDs? | In most cases, yes. There is no direct dangerous interaction between gabapentin and NSAIDs like ibuprofen or celecoxib. However, both can affect the kidneys in susceptible people, especially if you are elderly, dehydrated, or have kidney disease. Use the combination only under medical guidance and keep hydrated. |
| Can gabapentin cause confusion in the elderly? | Yes, gabapentin can cause confusion, drowsiness, dizziness, and falls in older adults. This is dose-related and more likely if kidney function is reduced. For elderly patients, I start with a very low dose, increase slowly, and review regularly. If confusion appears, the dose should be reduced or the medicine stopped under medical supervision. |
| Can I take gabapentin for mastitis pain? | Gabapentin is not a first-line treatment for acute mastitis pain. Mastitis requires antibiotics and anti-inflammatory treatment. However, gabapentin may be considered later if you develop persistent neuropathic breast pain after the infection has resolved. Always see your doctor for a breast examination first. |
Gabapentin is a prescription-only medicine, so you cannot buy it over the counter. The right step is to book an appointment with your GP. If you have nerve pain, bring a list of your symptoms, what makes the pain better or worse, and any medicines you already take. Your doctor can assess whether gabapentin is appropriate, arrange PBS authority if needed, and give you a private script for off-label uses such as hot flushes or anxiety.
When you and your doctor agree on gabapentin, you can fill the prescription at any Australian pharmacy. Many brands are available, and PBS subsidies can reduce the cost significantly for approved conditions. Always take it exactly as prescribed, do not share it, and do not stop it suddenly.
