How does this medication work? What will it do for me?
Rufinamide belongs to the class of medications called antiepileptics (anti-seizure medications). It is used along with other seizure medications to help control the seizures associated with Lennox-Gastaut syndrome in adults and children 4 years of age and older. Lennox-Gastaut syndrome is a seizure disorder where the person experiences frequent seizures and different types of seizures. Rufinamide is not used to treat other seizure disorders.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Abnormal heart rhythms: Rufinamide can cause changes to the normal rhythm of the heart, including an irregular heartbeat called QT shortening. QT shortening is a serious condition that can cause fainting and life-threatening heart rhythm problems.
If you are at risk for heart rhythm problems or are taking medications that cause QT shortening (e.g., digoxin, mexiletine, phenytoin, magnesium sulfate), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. People who have or have had short QT syndrome or a family history of short QT syndrome should not take rufinamide.
Birth control: As with other anti-seizure medications, rufinamide may reduce the effectiveness of oral contraceptives or other female hormonal treatments. It is advisable to use a non-hormonal form of birth control while you are taking this medication. Contact your doctor immediately if you experience changes in your menstrual pattern such as breakthrough bleeding while taking rufinamide.
Drowsiness/reduced alertness: People with uncontrolled epilepsy should not drive or handle potentially dangerous machinery. Common side effects of rufinamide include dizziness, problems with muscle coordination, drowsiness, double vision, and blurred vision. Do not undertake activities requiring mental alertness or physical coordination until you determine how rufinamide affects you.
Galactose Intolerance/Glucose Malabsorption: This medication contains lactose. If you have lactose intolerance or galactose malabsorption you should not take this medication.
Hypersensitivity (allergic) reactions: Rarely, rufinamide can cause severe allergic reactions called "hypersensitivity syndrome," which may be life-threatening. This reaction involves a number of organs in the body and may be fatal if not treated quickly. Stop taking the medication and get immediate medical attention if you have symptoms of a severe allergic reaction, including fever, swollen glands, yellowing of the skin or eyes, or flu-like symptoms with skin rash or blistering.
Stopping the medication: Suddenly stopping any antiepileptic medication may cause rebound seizures. In general, the medication should be stopped gradually, as directed by your doctor, to minimize this risk. Before stopping rufinamide, contact your doctor for guidance.
Suicidal thoughts or behaviour and depression: Like other antiepileptic medications, rufinamide may cause thoughts of suicide or harming oneself. People with epilepsy may also experience depression.
If you experience agitation, restlessness, anxiety, aggressiveness, irritability, unusual changes in behaviour or mood, not feeling like yourself, or wanting to hurt yourself or others, contact your doctor immediately. If you notice these side effects in a family member who is taking this medication, contact their doctor immediately.
Vision problems: Rufinamide may cause vision changes or problems, including blurred vision, seeing double, dry eyes, and eye infections. Report any changes in your vision to your doctor as soon as possible.
Pregnancy: The effect of rufinamide on a developing baby when taken during pregnancy is unclear. This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Do not stop taking the medication until you’ve consulted your doctor, since doing so can cause rebound seizures that may be harmful to the mother and unborn baby.
Breast-feeding: This medication may pass into breast milk. If you are a breast-feeding mother and are taking rufinamide, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using rufinamide for children under 1 year of age have not been established.
Seniors: The use of rufinamide by people over 65 years of age has not been well studied. Seniors are at increased risk of side effects of many medications and a lower than normal dose of rufinamide may be appropriate.
