Gabapentin: A Doctor’s Review for Australians Over 30
By a practising Australian GP
Attention: Is Nerve Pain or Relentless Itching Stealing Your Life?
Do you wake at 3 a.m. with burning, tingling, or stabbing pain in your feet, hands, or back? Does itching from kidney disease, shingles, or nerve damage make you want to scratch your skin raw? Are you tired of painkillers that either don’t work, leave you constipated, or make your head foggy? If you’re over 30, these problems become more common — and they can steal your sleep, your work, and your joy.
You are not alone. Millions of Australians live with nerve-related pain and itch every day. But there is real hope. As a GP, I want to introduce you to gabapentin — a medication that has helped thousands of my patients regain control of their lives. It is not an opioid, it does not damage your stomach, and when used correctly, it can be life-changing.
Interest: What Is Gabapentin and How Does It Work?
Gabapentin is a prescription medicine approved by the Therapeutic Goods Administration (TGA) in Australia. It was first developed to treat epilepsy, but doctors quickly discovered that it also calms overactive nerve signals throughout the body. That makes it incredibly useful for many conditions beyond seizures — especially nerve pain, neuropathic itch, and certain movement disorders.
Think of your nerves like electrical wiring. When nerves are damaged or irritated, they fire too many signals, causing pain, burning, itching, or involuntary movements. Gabapentin works by reducing the release of excitatory chemicals in the brain and spinal cord, effectively “turning down the volume” on those faulty signals. It does not mask the pain like opioids; it addresses the nerve hyperactivity at its source.
In Australia, gabapentin is listed on the Pharmaceutical Benefits Scheme (PBS) for certain types of neuropathic pain and epilepsy, meaning you may pay a reduced price at your local chemist with a valid prescription. It is available in capsules, tablets, and liquid form, with doses tailored to your kidneys and condition.
Your Questions Answered: A Doctor’s Honest Table
Below I answer the most common questions my patients over 30 ask me about gabapentin. This is real-world clinical experience combined with current evidence.
| Question | Doctor’s Answer | What You Should Do |
|---|---|---|
| Can I take gabapentin for cancer pain? | Yes, very often. Cancer pain frequently has a nerve component — from a tumour pressing on nerves, from chemotherapy, or from surgery. Gabapentin is used as an add-on to standard cancer painkillers. It can reduce the amount of opioids you need by 20–30%, giving better pain relief with fewer side effects like constipation and drowsiness. | Ask your oncologist or palliative care team about adding gabapentin. Start low and increase slowly. |
| Can I take gabapentin if I have tuberculosis? | Gabapentin does not treat tuberculosis itself, but it is often safe to take if you have TB. In fact, one of the first-line TB medicines, isoniazid, commonly causes painful nerve damage (peripheral neuropathy). Gabapentin is an excellent choice to relieve that nerve pain. There are no major dangerous interactions with TB antibiotics, but your kidney function must be checked because gabapentin is removed by the kidneys. | Tell your GP and TB specialist. You may need a kidney function blood test and a lower starting dose. |
| Can I take gabapentin for colic in infants? | No. Gabapentin is not approved or studied for infant colic. Its safety in babies is unknown, and giving adult nerve medication to an infant can be dangerous. Colic is distressing but usually improves on its own by 4–6 months of age. Please do not use gabapentin for this purpose. | See a paediatrician or child health nurse for safe colic strategies. |
| Can gabapentin cause constipation? | Yes, it can — but it is usually much milder than constipation from opioids like codeine, oxycodone, or tramadol. About 5–10% of patients notice harder stools or less frequent bowel movements, especially at higher doses. | Increase water, fibre, and exercise. If severe, your GP may lower the dose or add a gentle laxative. Do not stop suddenly. |
| Can I take gabapentin for pruritus (itching)? | Yes, this is one of the most underappreciated uses. Gabapentin is very effective for neuropathic itch — itching caused by nerve damage rather than skin allergy. This includes itching from kidney disease, shingles, brachioradial pruritus (itchy arms), notalgia paresthetica (itchy back), and diabetic nerve itch. Many patients find their itch disappears within days. | If your itch has not responded to antihistamines or steroid creams, ask your GP if it might be nerve-related. |
| Can gabapentin cause hearing loss? | This is rare. Some patients report tinnitus (ringing in the ears) or a feeling of muffled hearing, but true permanent hearing loss is uncommon. If you notice any change in hearing, report it immediately — but do not panic. In most cases, it improves when the dose is reduced or the medicine is stopped slowly. | Tell your GP if you notice ringing, fullness, or reduced hearing. A hearing test may be arranged. |
| Can gabapentin cause vomiting? | It can, especially when you first start or increase the dose. Nausea and occasional vomiting affect around 5–10% of users, but this usually settles within one to two weeks. Taking gabapentin with food can reduce stomach upset. | Start with a low dose at night. If vomiting persists, your GP may slow the dose increase or prescribe an anti-nausea medicine. |
| Can I take gabapentin for chorea? | Chorea is a movement disorder with jerky, dance-like movements — seen in Huntington’s disease, some autoimmune conditions, or as a side effect of certain medicines. Gabapentin has been used off-label for chorea with some success in small studies, but it is not a first-line treatment. A neurologist may try it if standard medicines fail. | Only use gabapentin for chorea under specialist supervision. Do not self-medicate for movement disorders. |
Desire: Why Gabapentin Could Be the Missing Piece for You
Imagine waking up without that electric-shock pain shooting through your feet. Imagine falling asleep because the burning has finally quietened. Imagine no longer scratching your skin until it bleeds. Imagine needing fewer opioid tablets, feeling clear-headed again, and having the energy to walk the dog, play with grandchildren, or return to work.
That is what gabapentin has done for many of my patients over 30. Here is why I regularly prescribe it:
- It is not an opioid. You avoid the addiction risks, severe constipation, and foggy head that often come with strong painkillers.
- It improves sleep. Gabapentin often makes you drowsy at night, which is a bonus when pain or itch has been keeping you awake.
- It is PBS-listed and affordable. Generic gabapentin costs very little with a Medicare card, making it accessible for pensioners and working Australians alike.
- It is flexible. Your GP can start you on a very low dose (e.g., 100–300 mg at night) and slowly increase until you get relief, minimising side effects.
- It has few serious interactions. Unlike many pain medicines, gabapentin does not damage the liver, stomach, or kidneys when used at the correct dose.
Consider this real scenario from my clinic: a 58-year-old woman with diabetic nerve pain was taking tramadol four times a day, constipated, drowsy, and housebound. We started gabapentin at night, slowly increased to 600 mg three times a day, and within six weeks she had halved her tramadol, was walking daily, and said, “I feel like myself again.” That is the power of calming overactive nerves.
Action: Take the Next Step Today
You do not have to keep living with nerve pain, itch, or movement problems. Gabapentin is available at every Australian chemist — but only with a prescription from your GP or specialist. The good news is that getting a script is straightforward if you describe your symptoms clearly.
Here is exactly what to do:
- Book an appointment with your GP. Say: “I’ve been reading about gabapentin for nerve pain/itching. Would it be suitable for me?”
- Bring this article to discuss the questions that matter to you. Your GP will order a kidney function blood test and may start you on a low dose at night.
- Be patient. Gabapentin works best when increased slowly over a few weeks. Do not stop it suddenly if you have been taking it regularly.
- Follow up. After 2–4 weeks, tell your GP what has improved and any side effects. The dose can be fine-tuned.
Do not buy gabapentin online without a prescription — in Australia that is illegal and unsafe. But do not wait to ask your doctor. Every day with uncontrolled nerve pain is a day lost. Take control. Talk to your GP about gabapentin today, and you could be sleeping peacefully and living fully again within weeks.
