Horizant Information:

What is Horizant?

The Horizant drug is the brand name for the extended release version of the drug gabapentin, an anticonvulsant of the gamma aminobutyric acid class; it is prescribed to treat restless leg syndrome (RLS), and nerve pain resulting from post-herpetic neuralgia (PHN). When prescribed for PHN (post-herpetic neuralgia), it changes how the body perceives pain; it is not known how it works in the treatment of RLS.

How do I take Horizant?

Horizant is dispensed in tablet form and taken orally, once a day, with or without food, usually with a full glass of water. These extended release tablets cannot be substituted for another formulation of gabapentin. 

Before taking Horizant, tell your doctor if:

  • You are allergic to gabapentin or any of the ingredients in the Horizant drug
  • You are pregnant, planning a pregnancy, or are nursing a child
  • You are taking any prescription or non-prescription medications, vitamins, or supplements
  • You are taking hydrocodone, naproxen, or other formulations of gabapentin
  • You are taking antihistamines, or any medications that may make your drowsy or dizzy
  • You are taking antacids, especially those whose formulation include aluminum or magnesium
  • You have, or have had, kidney disease

What are the possible side effects of taking Horizant?

Some individuals have reported side effects after taking Horizant. Less severe symptoms include vision problems, headache, tremors, changes in appetite, pain or swelling in the joints, back, or limbs, weight loss or gain, anxiety, dizziness, ear pain, confusion, weakness, malaise, memory loss, constipation, diarrhea, nausea, vomiting, or flu-like symptoms. If any of these conditions persist or worsen, contact your healthcare provider.

Severe side effects requiring immediate medical attention include seizures or symptoms of an allergic reaction (rash, hives, blistering skin, itching, swelling of the mouth, lips, tongue, or throat, or difficulty breathing or swallowing).

What if I forget to take a dose of Horizant?

If you forget to take the scheduled dose of your Horizant, take it as soon as you remember and are able, then resume the normal regimen. However, if the time is near for your next scheduled dose, forego the one missed and resume the regular schedule. Do not take multiple doses or change dosing intervals to make up for one that was missed.

How do I store Horizant?

Store Horizant in its original container, out of the reach of children and away from the extremes of temperature and humidity. Dispose of unused or expired quantities according to the directions of a pharmacist.

What happens if I overdose on Horizant?

If an overdose of Horizant is suspected, contact Poison Control at 1-800-222-1222. If the individual has stopped breathing or lost consciousness, contact Emergency Services at 911. Signs of an overdose include slurred speech, diarrhea, double vision, and drowsiness.


Contact your doctor if you become pregnant while taking this drug. Horizant can make you dizzy or drowsy; do not drive, operate heavy machinery or equipment, use power tools, or handle firearms until its effects are known. Speak with doctor before drinking alcohol while taking this medication. Horizant may have a negative effect on urine tests.

Brand Names

Horizant is the brand name of the extended-release formula of the drug gabapentin, which is also marketed as Neurontin, Gralise, and Gabarone.
