It is also used to treat restless leg syndrome and pain associated with nerve disorders including shingles, and is sometimes prescribed to control pain after minor surgical procedures. According to WebMD, the oral medication Gabapentin is sold under the brand name Neurontin.
The medication is only available with a doctor's prescription and the dosage varies dependent on the patient and the condition being treated. Depending on the needs of the patient, Neurontin may be prescribed in one of three forms, including immediate-release, sustained-release and enacarbil sustained-release formulations.
