Gabapentin is sometimes prescribed off-label for anxiety, especially when traditional treatments are ineffective or not well tolerated. It works by calming overactive nerve activity, which may help reduce physical symptoms of anxiety such as restlessness and tension. While some patients report improvement, gabapentin is not FDA-approved for anxiety, and its effectiveness varies. Common side effects include dizziness, fatigue, and coordination problems. It may also cause mood changes in some individuals. Gabapentin should not be stopped abruptly due to withdrawal risks. Patients should discuss the benefits, risks, and alternative treatments with their healthcare provider before using it for anxiety.
