Gabapentin Dosage Chart, Gabapentin Dosage for Adults and Gabapentin Dosage for Children

Gabapentin is a generic prescription drug that is FDA-approved as an add-on treatment with other medications for partial seizures in those with epilepsy.

It can also be used to treat nerve pain from postherpetic neuralgia (a complication of shingles). Gabapentin is frequently prescribed off-label for many other conditions, such as diabetic peripheral neuropathy, fibromyalgia, and alcohol dependence.

Gabapentin is typically prescribed as a generic, but the drug is also available under the brand names Neurontin and Gralise. Some patients may be prescribed drugs very similar to gabapentin—such as Horizant (gabapentin enacarbil) or Lyrica (pregabalin)—instead of gabapentin.

The usual dose for epilepsy starts at 300 mg on the first day. The dose can then be increased until an effective dose is reached, which is usually 300 to 600mg taken three times per day.

What should you know before you buy gabapentin Online

Gabapentin (Generic Neurontin ) was developed to treat epilepsy, but it is now used to treat various forms of chronic pain. It works by reducing the number of signals sent through the nerves. If the signals are reduced then the pain will be reduced. Research has shown that Gabapentin can help in treating various types of nerve pain.

Some Research Team performed searches to look for clinical trials where gabapentin was used to treat neuropathic pain or fibromyalgia. They found that 5633 participants had been involved in 37 studies of reasonable quality.  They tested gabapentin against placebo for four weeks or more.  Studies lasting only one or two weeks are unhelpful when pain can last for years.

Neuropathic pain is pain coming from damaged nerves. It differs from pain messages carried along healthy nerves from damaged tissue (a fall, cut, or arthritic knee). Neuropathic pain is treated by different medicines than pain from damaged tissue.

Medicines like paracetamol or ibuprofen are not effective in neuropathic pain, while medicines that are sometimes used to treat depression or epilepsy can be very effective in some people with neuropathic pain.  Our understanding of fibromyalgia (a condition of persistent, widespread pain and tenderness, sleep problems, and fatigue) is poor, but fibromyalgia can respond to the same medicines as neuropathic pain.

Gabapentin is helpful for some people with chronic neuropathic pain or fibromyalgia. Gabapentin comes as a capsule, tablet, or solution. You take it by mouth. Gabapentin is available as the brand-name drugs Neurontin, Gralise, and Horizant.  It’s also available as a generic drug.
