Phenobarbital

Phenobarbital is a medication primarily used to control seizures in epilepsy. It works by enhancing the activity of a brain chemical called GABA, which helps calm nerve activity and prevent seizural bursts. By stabilizing electrical activity in the brain, phenobarbital reduces the frequency and severity of seizures. It has been used for many years and is effective, but it can cause side effects like drowsiness or dizziness. Because of its potency, it is typically prescribed and monitored carefully by healthcare providers, especially when starting or adjusting the dose.
