However, side effects are possible and may include things like dizziness, headache, and drowsiness.
Horizant™ (gabapentin enacarbil) is a prescription medication approved for treating the following conditions:
How Does Horizant Work?It is not known exactly how this medication works to treat restless legs syndrome or postherpetic neuralgia. Preliminary data suggests that Horizant binds to certain parts of calcium channels in the central nervous system, and this may be how it works for RLS and postherpetic neuralgia.
Some general considerations to keep in mind during treatment with Horizant include the following:
- Horizant comes in extended-release tablet form. It is usually taken by mouth once a day, with food, at approximately 5 p.m. (for RLS) or twice a day (for postherpetic neuralgia).
- You must swallow the tablets whole; do not chew, cut, crush, or dissolve them, as this causes the medication to be released too quickly.
- For this medication to work properly, it must be taken as prescribed.
