Clobazam is a medication used to help treat seizures associated with Lennox-Gastaut syndrome in patients who are 2 years old or older. It works by enhancing the effects of a natural calming substance in the brain, which helps reduce seizure activity. The medication comes as an oral suspension and is usually taken once or twice a day, starting at 5 mg for patients weighing 30 kg or less, and 10 mg for those over 30 kg, with a maximum dose of 20 mg or 40 mg daily, depending on weight. It's important to know that clobazam should not be taken by anyone who has had a serious allergic reaction to it or its ingredients. Additionally, if you are taking strong medications that affect liver enzymes, such as ketoconazole, you may need a dose adjustment while using clobazam.
