Banzel is a prescription medication approved by the FDA to treat seizures in patients with Lennox-Gastaut Syndrome (LGS). It contains the active ingredient rufinamide. Rufinamide is in a class of medications called anticonvulsants. It works by acting on the sodium channels in the brain that may cause seizures. Banzel is taken with other medications to prevent or control seizures associated with LGS.

Uses and Dosage

Banzel is an oral tablet medication that is generally taken with food, usually twice a day at around the same time every day. The tablets may be swallowed whole, broken in half on the score mark, or crushed. While the tablet may help control your condition, it will not cure it. Even if you feel well, continue taking Banzel, and do not stop suddenly without consulting your doctor. If you suddenly stop taking Banzel, your seizures may worsen. Your doctor will likely decrease your dose gradually.

Generally, your doctor will begin with a low dose of Banzel and gradually increase your dose, but not more than once every other day. Take the tablet exactly as directed by your doctor, neither more nor less, nor more often than prescribed.

The recommended starting daily dose of Banzel in adults with Lennox-Gastaut Syndrome is 400 to 800 mg per day administered in two equally divided doses. The target dosage was achieved in 88% of patients, and most patients reached the target dose within 7 days. However, the specific dosage may be adjusted based on the patient's needs and response to the medication.
