ZONISAMIDE
About
ZONISAMIDE belongs to a group of medicines called anti-convulsants or anti-epileptics used to treat epilepsy (seizures/fits). Epilepsy is a sudden rush of electricity in the brain. In epilepsy the brain's electrical rhythms become imbalanced, resulting in recurrent seizures. In patients with seizures, the typical brain electrical pattern is disrupted by sudden bursts of electrical impulses that affect an individual’s consciousness, movements, or sensations.
ZONISAMIDE contains 'Zonisamide’ that reduces the abnormal and excessive activity of nerve impulses in the brain that cause fits or seizures. Thereby helps in controlling seizures. In patients with seizures, the typical brain electrical pattern is disrupted by sudden bursts of electrical impulses that affect an individual’s consciousness, movements, or sensations. ZONISAMIDE is used alone or in combination to treat and prevent partial seizures in adults and children above 6 years of age.
Take ZONISAMIDE as prescribed by your doctor. You are advised to take ZONISAMIDE for as long as your doctor has prescribed it for you depending on your medical condition. In some cases, you may experience certain common side-effects such as dizziness, irritability, loss of appetite, memory impairment, double vision, confusion, depression, constipation, nausea, headache, uncontrolled movements. Most of these side-effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side effects persistently.
To treat your condition effectually, continue taking ZONISAMIDE for as long as your doctor has prescribed. Please do not stop taking ZONISAMIDE without consulting your doctor to avoid worsening of seizures. Do not take ZONISAMIDE if you are pregnant or planning for pregnancy unless prescribed by the doctor. Avoid taking ZONISAMIDE while breastfeeding as it may cause side-effects in the breastfed babies. ZONISAMIDE should not be given to children unless prescribed. ZONISAMIDE causes drowsiness and dizziness, so drive if you are alert. ZONISAMIDE should not be given to children unless prescribed. Avoid consuming alcohol along with ZONISAMIDE as it could lead to increased dizziness and sleepiness. Consult your doctor immediately if you experience mood swings or suicidal tendencies. ZONISAMIDE can cause permanent vision loss, inform your doctor immediately if you have any eye pain, redness, or any changes in your vision. Keep your doctor informed about your health condition and medicines to rule out any side effects.
Uses of ZONISAMIDE
Medicinal Benefits
ZONISAMIDE belongs to a group of medicines called anti-convulsants or anti-epileptics. ZONISAMIDE is used to treat epilepsy/seizures/fits. Epilepsy is a sudden rush of electricity in the brain. ZONISAMIDE works by blocking the sodium and calcium current in the brain and suppress the abnormal and excessive activity of nerve impulses in the brain that cause fits and pain. Thereby help in controlling seizures. ZONISAMIDE is used alone or in combination to treat and prevent partial seizures and generalized seizures in adults. ZONISAMIDE may be used as solo therapy or in combination in treating and preventing seizures in children above 6 years of age. ZONISAMIDE is not associated with any psychological or physical dependence, and there is no potential for abuse.

Safety Advice
Alcohol
unsafeAvoid consumption of alcohol while taking ZONISAMIDE as it may increase dizziness and sleepiness.
Pregnancy
cautionAvoid taking ZONISAMIDE if you are pregnant unless prescribed by a doctor to lead to serious birth defects/congenital disabilities. Please consult your doctor if you have any concerns regarding this, your doctor will prescribe only if the benefits outweigh the risks.
Breast Feeding

Habit Forming
Diet & Lifestyle Advise
- A ketogenic diet (low in carbohydrates and high in fats) is recommended for children with epilepsy. This diet helps in utilizing fat instead of glucose for the generation of energy.
- Atkins diet (high fay and controlled carbohydrates) is recommended for adolescents and adults.
- Rest well, get plenty of sleep.
- Avoid smoking and alcohol consumption.
- Exercise, meditation, and yoga can help lower stress, decrease pain sensitivity, and improves coping skills.
- Prepare your living area; small changes may reduce the risk of physical injury during a seizure.
- Install an alarm or emergency device to get assistance during a seizure attack.
Special Advise
- Regular monitoring of bicarbonate levels while taking ZONISAMIDE is advised to prevent low blood bicarbonate levels.
- ZONISAMIDE may cause low blood cell count, so if you have any red or purple spots on the body, let your doctor know about this.
Patients Concern
Disease/Condition Glossary
Epilepsy: Epilepsy is a sudden rush of electricity in the brain. It is a disorder of the nervous system which occurs due to disturbed nerve cell activity in the brain. In epilepsy the brain's electrical rhythms become imbalanced, resulting in recurrent seizures. In patients with seizures, the typical brain electrical pattern is disrupted by sudden bursts of electrical impulses that affect an individual's consciousness, movements, or sensations. Seizures are of two types: generalized and partial seizures. Generalized seizures affect the entire brain, whereas partial seizures affect only a part of the brain. Seizures can cause uncontrollable muscle twitches and spasms. Stronger seizures may cause people to become confused or unconscious. Possible causes include high fever, trauma, genetic disorder, brain injury, or stroke.
FAQs
ZONISAMIDE consists of 'zonisamide' that decreases the brain's excessive and abnormal nerve activity by blocking sodium and calcium currents in your brain and body. This reduces abnormal electrical activity between your nerve cells.
