Gabapentin is a medication primarily used to treat nerve pain and seizures. It works by affecting the way nerves send messages to the brain, helping to reduce pain and prevent seizures. Doctors often prescribe it for conditions like neuropathic pain and epilepsy. In addition to its main uses, Gabapentin may also be prescribed for other conditions, such as anxiety disorders and restless leg syndrome. It is available in various forms, including capsules and tablets, and is usually taken several times a day. As with any medication, it is important to follow a doctor's instructions and be aware of potential side effects.
