Gabapentin 600 mg is a commonly prescribed dosage that helps manage nerve-related pain (neuropathy), partial seizures, and sometimes even off-label issues like anxiety or fibromyalgia. Typically, this dosage is part of a gradual titration plan, where the amount is increased over time based on how the patient responds and their tolerance. Depending on the condition being treated and the doctor's advice, it can be taken once or twice a day.
