Drug Information: Zonisamide
URL of this page: http://www.nlm.nih.gov/medlineplus/druginfo/medmaster/a603008.html
(zoe nis' a mide)IMPORTANT WARNING:
| [Posted 01/31/2008] FDA informed healthcare professionals that the Agency has analyzed reports of suicidality (suicidal behavior or ideation) from placebo-controlled clinical studies of eleven drugs used to treat epilepsy as well as psychiatric disorders, and other conditions. In the FDA's analysis, patients receiving antiepileptic drugs had approximately twice the risk of suicidal behavior or ideation (0.43%) compared to patients receiving placebo (0.22%). The increased risk of suicidal behavior and suicidal ideation was observed as early as one week after starting the antiepileptic drug and continued through 24 weeks. The results were generally consistent among the eleven drugs. The relative risk for suicidality was higher in patients with epilepsy compared to patients who were given one of the drugs in the class for psychiatric or other conditions.Healthcare professionals should closely monitor all patients currently taking or starting any antiepileptic drug for notable changes in behavior that could indicate the emergence or worsening of suicidal thoughts or behavior or depression.The drugs included in the analyses include (some of these drugs are also available in generic form): Carbamazepine (marketed as Carbatrol, Equetro, Tegretol, Tegretol XR)Felbamate (marketed as Felbatol)Gabapentin (marketed as Neurontin) Lamotrigine (marketed as Lamictal) Levetiracetam (marketed as Keppra) Oxcarbazepine (marketed as Trileptal)Pregabalin (marketed as Lyrica) Tiagabine (marketed as Gabitril)Topiramate (marketed as Topamax) Valproate (marketed as Depakote, Depakote ER, Depakene, Depacon) Zonisamide (marketed as Zonegran) Although the 11 drugs listed above were the ones included in the analysis, FDA expects that the increased risk of suicidality is shared by all antiepileptic drugs and anticipates that the class labeling changes will be applied broadly. For more information visit the FDA website at: http://www.fda.gov/medwatch/safety/2008/safety08.htm#Antiepileptic and http://www.fda.gov/cder/drug/InfoSheets/HCP/antiepilepticsHCP.htm. |
Why is this medication prescribed?
Pending revision, the material in this section should be considered in light of more recently available information in the MedWatch notification at the beginning of this monograph.
Zonisamide is used in combination with other medications to treat seizures in adults with epilepsy. Zonisamide is in a class of medications called anticonvulsants. It works by decreasing abnormal excitement in the brain.
How should this medicine be used?
Zonisamide comes as a capsule to take by mouth. It is usually taken once or twice a day with or without food. To help you remember to take zonisamide, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take zonisamide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the capsules whole; do not split, chew, or crush them.
Your doctor will probably start you on a low dose of zonisamide and gradually increase your dose, not more than once every 2 weeks.
Zonisamide controls epilepsy but does not cure it. It may take 2 weeks or longer before you feel the full benefit of zonisamide. Continue to take zonisamide even if you feel well. Do not stop taking zonisamide without talking to your doctor. If you suddenly stop taking zonisamide, your seizures may become worse. Your doctor will probably decrease your dose gradually.
Other uses for this medicine
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
What special precautions should I follow?
Pending revision, the material in this section should be considered in light of more recently available information in the MedWatch notification at the beginning of this monograph.
Before taking zonisamide,
- tell your doctor and pharmacist if you are allergic to zonisamide, celecoxib (Celebrex), diuretics ('water pills'), oral medications for diabetes, sulfa drugs, or any other medications.
- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking. Be sure to mention any of the following: antifungals such as fluconazole (Diflucan), itraconazole (Sporanox), and ketoconazole (Nizoral); antihistamines; carbamazepine (Carbatrol, Tegretol), cimetidine (Tagamet); clarithromycin (Biaxin); cyclosporine (Neoral, Sandimmune); danazol (Danocrine); delavirdine (Rescriptor); dexamethasone (Decadron, Dexpak), diltiazem (Cardizem, Dilacor, Tiazac); ethosuximide (Zarontin), erythromycin (E.E.S., E-Mycin, Erythrocin); fluoxetine (Prozac, Sarafem); fluvoxamine (Luvox); HIV protease inhibitors such as indinavir (Crixivan) and ritonavir (Norvir); ipratropium (Atrovent); isoniazid (INH, Nydrazid); medications for irritable bowel disease, motion sickness, Parkinson's disease, ulcers, or urinary problems; metronidazole (Flagyl); nefazodone (Serzone); oral contraceptives (birth control pills); oral medications for glaucoma such as acetazolamide (Diamox); phenobarbital (Luminal, Solfoton); phenytoin (Dilantin); primidone (Mysoline); rifabutin (Mycobutin), rifampin (Rifadin, Rimactane); troglitazone (Rezulin); troleandomycin (TAO); valproic acid (Depakene, Depakote); verapamil (Calan, Covera, Isoptin, Verelan); and zafirlukast (Accolate). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- tell your doctor if you have or have ever had liver or kidney disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking zonisamide, call your doctor. Zonisamide may harm the fetus.

- you should know that zonisamide may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
- remember that alcohol can add to the drowsiness caused by this medication.
- you should know that you may be more likely to develop kidney stones while taking zonisamide. You should drink 6-8 glasses of water daily to help prevent kidney stones from forming.
- you should know that zonisamide can prevent you from sweating and make it harder for your body to cool down when it gets very hot. This happens most often in warm weather and to children who take zonisamide. (Children should not normally take zonisamide, but in some cases, a doctor will decide whether it is the best choice.) You should avoid exposure to heat and notify your doctor if you have a fever and/or are not sweating as usual.
What special dietary instructions should I follow?
Talk to your doctor about drinking grapefruit juice while taking this medicine.
What should I do if I forget a dose?
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
