It is generally not recommended to abruptly stop taking gabapentin, especially if you have been taking it for a long period of time or at high doses. Suddenly stopping gabapentin can lead to withdrawal symptoms, such as anxiety, insomnia, nausea, sweating, and seizures. It is important to work with your doctor to gradually taper off gabapentin to minimize the risk of withdrawal symptoms. Your doctor can provide you with a safe and effective plan to discontinue gabapentin.
