If you are using gabapentin enacarbil, it's important to be aware of potential side effects. Although most people tolerate this medication well, reactions may include things like dizziness, drowsiness, and nausea.

If you develop any troublesome side effects during treatment, or if something "just doesn't seem right," contact your healthcare provider.

An Introduction to Gabapentin Enacarbil Side Effects

Just like any medicine, gabapentin enacarbil (Horizant™) can cause side effects. However, not everyone who takes the medication will have problems. In fact, most people tolerate it quite well.
