Medicines have benefits and risks. The risks are the chances that something unwanted or unexpected could happen to you when you use them. You can protect yourself by searching summaries of recent safety Zonegran alerts and medication adverse reports. Search for documented Zonegran side effects on the label or the drug's package insert. You may also want to speak with your pharmacist or healthcare provider. Sometimes there are risks that only come to light after a medical product gets on the market and is used in a larger number of patients, for a longer period of time, and in patients whose health characteristics are different from those of the patients studied before approval.

Zonisamide (marketed as Zonegran, and generics)

Audience: Neurological healthcare professionals

[Posted 02/23/2009] FDA notified healthcare professionals that updated clinical data has determined that treatment with zonisamide, indicated as adjunctive therapy in the treatment of partial seizures in adults with epilepsy, can cause metabolic acidosis in some patients. Patients with predisposing conditions or therapies may be at greater risk for developing metabolic acidosis and the risk of zonisamide-induced metabolic acidosis appears to be more frequent and severe in younger patients. FDA recommends that healthcare professionals measure serum bicarbonate before starting treatment and periodically during treatment with zonisamide, even in the absence of symptoms and is working with the makers of zonisamide to revise the product labeling to reflect this new safety information. The notification includes recommendations for healthcare providers, information for patients, and a data summary.
