What is Banzel?

Banzel (rufinamide) is a prescription medicine used to help treat seizures in people with Lennox-Gastaut Syndrome (LGS), a severe form of epilepsy that begins in childhood. 

It’s used alongside other seizure medications for adults and children who are at least one year old. Banzel comes in tablets and a liquid form.

Common side effects include headache, dizziness, tiredness, sleepiness, nausea, and vomiting.

Sometimes, doctors may also use Banzel as off-label to treat other types of seizures called partial seizures, which affect only one part of the brain.

How Does Banzel Work?

Banzel is a medicine that helps prevent seizures. It contains an ingredient called rufinamide, which is an anticonvulsant. Rufinamide works by targeting sodium channels in the brain. These channels can carry too much electrical activity, which can cause seizures. 

By acting on these sodium channels, Banzel helps to control and reduce the excessive electrical charges, making seizures less likely to happen.

Dosage Information and Usage

The dosage of Banzel depends on the patient’s age and weight, and it should always be taken with food. It’s important to follow the prescribed dosage and administration instructions for the best results and to reduce the risk of side effects.

Dosage Form and Strengths

Film-coated Tablets:

  • 200 mg (pink, scored on both sides)
  • 400 mg (pink, scored on both sides)

Oral Suspension:

  • 40 mg/mL (white to off-white opaque liquid)

Indications of Use for Banzel

Patients aged one year and older, including adults, can use Banzel to help reduce the frequency of their seizures.

  • For children (1 year to less than 17 years): The starting dose is about 10 mg for each kilogram of the child’s weight per day, split into two doses. The dose is increased by about 10 mg/kg every other day until it reaches a maximum of 45 mg/kg per day, not to exceed 3200 mg per day.
  • For adults (17 years and older): The starting dose is 400 to 800 mg per day, split into two doses. The dose is increased by 400-800 mg every other day until it reaches a maximum of 3200 mg per day.

Banzel should always be taken with food. The tablets can be swallowed whole, cut in half, or crushed. If using the oral suspension, shake the bottle well before each use and measure the dose with the provided dosing syringe.

Storage Information

Store Banzel tablets and oral suspension at room temperature, around 25°C (77°F). They can handle temperatures between 15°C and 30°C (59°F to 86°F). Keep the tablets in their bottle, and make sure the cap is tightly closed to protect them from moisture.

Store the oral suspension upright and always secure the cap after opening. Use the oral suspension within 90 days of opening the bottle, and discard any remaining liquid.

Side Effects

Banzel can help control seizures, but like all medications, it can cause side effects. It’s important to be aware of these side effects and to talk to your doctor if you experience any. Some side effects are common and mild, while others are rare but more serious.

Common Side Effects

  • Headache
  • Dizziness
  • Tiredness
  • Sleepiness
  • Nausea
  • Vomiting

Serious but Rare Side Effects

  • Allergic reactions (swelling of face, eyes, lips, or tongue)
  • Trouble swallowing or breathing
  • Skin rash or hives
  • Fever, swollen glands, or sore throat that do not go away
  • Yellowing of the skin or eyes (jaundice)
  • Dark urine
  • Unusual bruising or bleeding
  • Severe fatigue or weakness
  • Severe muscle pain
  • Increased frequency or worsening of seizures

If you experience any serious side effects, immediately contact your healthcare provider.

Warnings and Precautions

When taking Banzel, it’s important to be aware of potential risks and precautions to ensure the safe and effective use of the medication. Always consult your healthcare provider for personalized advice and report any unusual symptoms immediately.

General Precautions for Banzel Medication

  • Suicidal Thoughts and Behavior: Banzel, like other antiepileptic drugs, can increase the risk of suicidal thoughts and behavior. Patients should be monitored for any changes in mood, depression, or suicidal thoughts, especially when starting the medication.
  • Central Nervous System Reactions: Banzel may cause drowsiness, dizziness, and coordination problems. Patients should avoid driving or operating heavy machinery until they know how Banzel affects them.
  • QT Interval Shortening: Banzel can shorten the QT interval on an ECG, which measures the heart’s electrical activity. People with a family history of Short QT syndrome or those on other QT-shortening drugs should avoid using Banzel.
  • Multi-organ Hypersensitivity (DRESS): Banzel can cause a severe allergic reaction called DRESS, which may affect multiple organs. Symptoms can include fever, rash, and swollen glands. If you suspect DRESS, seek medical attention immediately.
  • Withdrawal: Banzel should not be stopped abruptly. Gradually reduce the dose under medical supervision to prevent increased seizures or status epilepticus.
  • Status Epilepticus: Some patients may experience status epilepticus, a condition where seizures last too long or occur too close together. Seek immediate medical help if this happens.
  • Leukopenia: Banzel can lower white blood cell counts, leading to an increased risk of infections. Regular blood tests may be required to monitor your white blood cell levels.


If you accidentally take too much Banzel, seek help immediately. Overdose management strategies can change, so it’s best to contact a Certified Poison Control Center for the latest advice. In one instance, an adult took a very high dose of 7200 mg of Banzel in a day without major symptoms and didn’t need medical treatment.

However, if necessary, the doctor might induce vomiting or flush out the stomach to remove any unabsorbed drug.

They will also monitor your vital signs and overall condition. While standard hemodialysis might not fully remove Banzel, it could be considered if needed.

Drug Interactions With Other Medications

When taking Banzel, it’s important to understand how it interacts with other medications you might be taking. Here’s a simplified overview of these interactions:

  • Effects of BANZEL on other AEDs: Banzel may have little impact on other antiepileptic drugs (AEDs) levels in the blood. However, in some cases, Banzel might decrease the levels of carbamazepine, and lamotrigine, or increase the levels of phenobarbital and phenytoin, especially in children or at higher Banzel doses.
  • Effects of Other AEDs on BANZEL: Some AEDs like carbamazepine, phenytoin, primidone, and phenobarbital can increase the clearance of Banzel from the body. This means Banzel might be removed from your body faster when taken with these drugs, particularly in children.
  • Valproate Interaction: If you’re taking valproate with Banzel, your doctor might start you on a lower dose of valproate to avoid side effects. Similarly, if you’re already on valproate, your doctor might start you on a lower dose of Banzel to reduce the risk of side effects.
  • Effects of BANZEL on Hormonal Contraceptives: Banzel might make hormonal contraceptives less effective. Female patients of childbearing age should consider using additional non-hormonal forms of contraception while taking Banzel to prevent unintended pregnancy.

Alternative Medications to Banzel

If Banzel isn’t the right fit for you, there are alternative medications to consider. Here are the following good alternatives to Banzel:

  • Clobazam
  • Cannabidiol
  • Fenfluramine
  • Fintepla
  • Sympazan

Communicate with your doctor to determine the best alternative based on individual needs and medical history.

Banzel is mainly approved for treating seizures linked to Lennox-Gastaut syndrome (LGS). However, it’s sometimes used off-label to manage partial seizures not related to LGS. These focal seizures occur in one area of the brain. Off-label use means the medication is prescribed for unapproved purposes based on the healthcare provider’s judgment and patient needs.
