What is Zonegran
ZonisamideThe Generic name of this drug
Treatment SummaryZonisamide is a medication used to treat partial-onset seizures in adults. It works by blocking the activity of sodium channels in the brain, reducing the amount of calcium in the cells, and increasing the uptake of the excitatory neurotransmitter glutamate. It may also bind to GABA receptors, which regulates the amount of inhibitory neurotransmitters in the brain.

Effectiveness
How Zonegran Affects PatientsZonisamide is used to stop the spread of seizures, including tonic convulsions and focal seizures. It can also help protect against memory loss and lipid peroxidation caused by a lack of oxygen. However, taking zonisamide can lead to potentially fatal reactions, such as Stevens-Johnson syndrome, toxic epidermal necrolysis, fulminant hepatic necrosis, agranulocytosis, and aplastic anemia. Other side effects may include hematological events, drug reaction with eosinophilia and systemic symptoms, multi-organ hypersensitivity, acute myopia, angle closure gl
How Zonegran works in the bodyThe exact way that zonisamide works to control seizures is not yet known. It appears to work by blocking sodium channels and reducing the electrical activity in the brain. It does this by altering how neurotransmitters, such as glutamate, GABA, dopamine, serotonin, and acetylcholine are made, released, and broken down. Zonisamide also binds to the GABA/benzodiazepine receptor ionophore complex without changing how much chloride goes through. Studies have shown that it does not affect the way glutamate or GABA are used by the brain.

Zonegran Toxicity & Overdose RiskTaking more than 800mg of zonisamide in a day is not recommended. In three cases of overdose, patients experienced symptoms of the central nervous system, including coma and slowed heart rate. Treatment for an overdose involves inducing vomiting or performing gastric lavage. Monitoring the patient's vital signs and providing general support care is also recommended. Renal dialysis may be used to remove zonisamide from the body, though its effectiveness has not been studied. Tests have not found zonisamide to cause cancer in humans, although it may cause mutations in cells and reproductive toxicity in rats.

Zonegran Reviews: What are patients saying about Zonegran?
5Patient Review
4/29/2013 Dr. prescribed Zonegran for chronic migraine, didn't help my migraines at all and seven years later still dealing with side effect- Parosmia.
5Patient Review
12/27/2013 I've been on this medicine for over a decade and it has really helped me. I haven't had a seizure since I started taking it. The only downside is that you have to drink a lot of water or else you might get kidney stones, but that's only happened to me three times in ten years.
4Patient Review
10/16/2013 I had to stop taking dut because it caused me to experience depression, suicidal thoughts, decreased appetite, sleep deprivation, nausea and diarrhea.
4Patient Review
10/21/2013 At first, this medication made me very tired. Now I'm worried about hair loss and wondering if it's a side effect. I've also lost weight since starting to take this drug, but it has been great for my seizures.
2Patient Review
2/8/2022 I unfortunately experienced one of the rare side effects called metabolic acidosis. After a month or two, I started feeling really anxious and had to go to the ER multiple times. I also had headaches and weird sensations in my brain. Overall, this treatment did not work out for me at all.
