Gabapentin can cause life-threatening breathing problems, especially if you already have a breathing disorder or if you use other medicines that can make you drowsy or slow your breathing. Seek emergency medical attention if you have very slow breathing.

Some people have thoughts about suicide or behavior changes while taking gabapentin. Stay alert to changes in your mood or symptoms. Report any new or worsening symptoms to your doctor.

Do not stop using gabapentin suddenly, even if you feel fine.

Tell your doctor if you have ever had:

  • breathing problems or lung disease, such as chronic obstructive pulmonary disease (COPD);
  • kidney disease (or if you are on dialysis);
  • diabetes;
  • depression, a mood disorder, or suicidal thoughts or actions;
  • a drug addiction;
  • a seizure (unless you take gabapentin to treat seizures);
  • liver disease;
  • heart disease; or
  • (for patients with RLS) if you are a day sleeper or work a night shift.

Seizure control is very important during pregnancy, and having a seizure could harm both mother and baby. Do not start or stop taking gabapentin for seizures without your doctor's advice, and tell your doctor right away if you become pregnant.

Both Gralise and Horizant should be taken with food.
