Gabapentin, an anticonvulsant for epilepsy and nerve pain, comes as tablets in 100mg to 800mg strengths under its own name and as the brand Neurontin.
Gabapentin
100/300/400/600/800mg
Gabapentin tablets in 100mg, 300mg, 400mg, 600mg and 800mg strengths, used for nerve pain and to help control seizures in epilepsy.
Gabapentin is an anticonvulsant, a medicine that calms overactive electrical signalling in the brain and spinal cord. It has two main jobs: helping control certain types of seizures in epilepsy, where it is used alongside other epilepsy medicines, and easing nerve pain — the burning, stabbing or aching kind that can follow shingles (postherpetic neuralgia) or come with diabetes or an old injury. It dampens the pain rather than repairing the nerve, so it is usually taken long term.
Think of it as breakfast, mid-afternoon and bedtime rather than three tablets at once: the doses are evenly spaced, and the gap overnight should not run past 12 hours. Swallow with water, with or without a meal. Nobody begins at a full dose; it starts small and is raised over a week or more.
Stopping gabapentin abruptly is the part to avoid. Anxiety, poor sleep, nausea, sweating and aches can set in, and people taking it for epilepsy may have more seizures. Reducing it slowly over days avoids this.
Sleepiness, tiredness and dizziness are the ones people notice most, often in the first days, and they tend to settle as the body adjusts. Swollen ankles or feet can appear too. A severe allergic reaction — swelling of the face or throat, a rash with breathing trouble — needs urgent treatment. Gabapentin can also change mood or behaviour, and some people find it habit-forming.
Anything else that slows the brain makes gabapentin's drowsiness and unsteadiness stronger: opioid painkillers, sleeping tablets and benzodiazepines among them. Alcohol has a similar effect. Antacids that contain aluminium or magnesium can stop gabapentin being absorbed if taken at the same time, so leave a gap of a few hours between the two.
Both products hold the same active ingredient in immediate-release tablet form. Gabapentin is the plain version, covering 100mg, 300mg, 400mg, 600mg and 800mg. Neurontin is the brand name for the same medicine and runs from 100mg to 600mg. If your dose is 800mg, only the plain range has a single tablet for it; the brand stops at 600mg. Neither comes as a capsule or liquid.
Gabapentin can be ordered online for delivery in Hong Kong. The range covers Gabapentin tablets in 100mg, 300mg, 400mg, 600mg and 800mg, and generic Neurontin tablets in 100mg, 300mg, 400mg and 600mg. A parcel that arrives damaged or misses the delivery window is sent again free, or refunded if that is not possible.
It depends on the product, strength and pack size. Each of the two gabapentin products listed here shows its current prices in HKD or the currency you select.
Yes, generic Neurontin is listed as 100mg, 300mg, 400mg and 600mg tablets and contains gabapentin. Plain Gabapentin tablets are also available, reaching up to 800mg. Both are tablet versions of the same ingredient.
Neurontin is a brand name of gabapentin, which is also sold as Gabantin, Gabapin and Gralise. Here, gabapentin can be bought online as generic Neurontin and gabapentin tablets. These are generics, not the original brand.
Expect a gradual change. In the first week most people are still on a low starting dose, so little may happen yet; nerve pain eases over the weeks that follow as the dose reaches its working level. For seizures, the sign is fewer of them over time, not something felt after one tablet.
Alcohol adds to the drowsiness, dizziness and unsteadiness gabapentin can cause, and the pair together can hit harder than either alone. If you do drink, keep it to a minimum and see how the tablets affect you before having more.
Stopping abruptly can bring withdrawal effects such as anxiety, trouble sleeping, nausea, sweating and aches, and seizures may become more frequent. Gabapentin is normally stepped down over a week or longer so the body can adjust.
Food does not change how gabapentin works, so you can take it with a meal or on an empty stomach. A full glass of water with each dose helps, and if the tablets make you feel queasy, taking them after food is often easier.
