Gabapentin is a medication primarily used to treat epilepsy and certain types of neuropathic pain. It works by affecting the way nerves transmit pain signals. In addition to its approved uses, gabapentin is sometimes prescribed off-label for conditions like anxiety, and migraines, and as an adjunctive therapy for various chronic pain conditions. It's important to take gabapentin as prescribed by a healthcare provider and be aware of potential side effects, including dizziness, drowsiness, and in some cases, a risk of dependence.
