Key takeaways
Gabapentin (Neurontin) and fluphenazine are both medications that require a prescription, but they belong to different medication classes and treat different conditions. Gabapentin is an antiepileptic medication used to treat certain seizures and nerve pain, including off-label use for nerve pain from diabetes. It is typically taken three times a day in tablet, capsule, or liquid form. Common side effects include dizziness and sleepiness. Fluphenazine, on the other hand, is a typical antipsychotic used to treat psychotic disorders. It is available in oral and injectable forms, with the injectable form being long-acting and administered every 4 to 6 weeks. Fluphenazine can cause side effects like drowsiness and movement problems. Unlike gabapentin, fluphenazine is not a controlled substance and does not have a risk of misuse. However, it can cause serious side effects like neuroleptic malignant syndrome and tardive dyskinesia, especially with long-term use. Both medications are available as a lower-cost generic.
