NEURONTIN may cause serious side effects

Gabapentin (Generic Neurontin ) is used to help control partial seizures (convulsions) in the treatment of epilepsy. This medicine cannot cure epilepsy and will only work to control seizures for as long as you continue to take it.

Gabapentin (Generic Neurontin ) is also used to manage a condition called postherpetic neuralgia, which is pain that occurs after shingles. It’s also taken for nerve pain. Nerve pain can be caused by different illnesses, including diabetes and shingles, or it can happen after an injury.

Gabapentin (Generic Neurontin ) works in the brain to prevent seizures and relieve pain for certain conditions in the nervous system. It is not used for routine pain caused by minor injuries or arthritis. Gabapentin is an anticonvulsant.

Occasionally, gabapentin (Generic Neurontin ) is used to prevent migraine headaches. Gabapentin (Neurontin) and pregabalin (Lyrica) are anticonvulsants and nerve pain medicines which have structural similarities to the inhibitory neurotransmitter GABA.

Gabapentin (Generic Neurontin ) is available only with your doctor’s prescription.

Gabapentin (Generic Neurontin ) was developed in 1993 and has indications for shingles (‘postherpetic neuralgia’) and partial-onset seizures. It has had a growing popularity in off-label uses for fibromyalgia, pain from a variety of causes, migraine, cocaine withdrawal, anxiety, and insomnia. A related compound, gabapentin encarbil (Horizant), is approved for shingles and restless leg syndrome. Pregabalin was developed in 2004 and is approved for nerve pain from diabetes and spinal cord injuries, fibromyalgia, and adjunctive treatment of partial-onset seizures. Although prescribed off-label for anxiety in the U.S., it is approved for this purpose in the U.K., where it is sometimes called the ‘new Valium’.
