Hypersensitivity to gabapentin or to any of the excipients

Common: Ataxia, nystagmus, fatigue, dizziness, edema, drowsiness, amnesia; dyspepsia, dry mouth, constipation, abdominal pain, and diarrhea; peripheral edema; rhinitis, pharyngitis, cough, pneumonia; diplopia, amblyopia; myalgia, arthralgia; pruritus, rash; leucopenia; erectile dysfunction, viral infections.

Gabapentin should be used with caution in patients with a history of mental disorders, renal impairment and undergoing hemodialysis, driving vehicles or operating machines.

False positive readings have been reported with some urinary protein tests in patients taking gabapentin.

Adverse effects usually mild or moderate and tend to decrease within 2 weeks of continued therapy.

Ataxia is often related to dosage. If the symptom does not subside after reducing dose, the drug administration should be discontinued.

If Stevens-Johnson syndrome is suspected, the drug administration should be discontinued.

Neuronstad should not be discontinued abruptly because of the possibility of increasing seizure frequency. Before gabapentin is discontinued or an alternative anticonvulsant is added to the regimen, such changes should be done gradually over a period of at least 7 days.

Neuronstad should be used during pregnancy only if the potential benefits justify the risk to the fetus. Gabapentin should be administered to nursing women only if the potential benefits justify the risk to the infant.

Neuronstad acts on the central nervous system and may cause drowsiness, dizziness or other related symptoms. This is especially true at the beginning of the treatment and after increase in dose. Patients should avoid dangerous activities like driving or operating machines.
