Phenobarbital is a medication that belongs to the class of barbiturate drugs. It is primarily used as an anticonvulsant to treat seizures and as a sedative to induce sleep. Phenobarbital works by increasing the activity of a neurotransmitter called GABA, which reduces the excitability of neurons in the brain. It is available in various forms, including tablets and injectable solutions. Phenobarbital can cause a range of side effects, including drowsiness, dizziness, confusion, and skin rash. It can also lead to dependence and addiction, and its use must be carefully monitored to avoid withdrawal symptoms and overdose.
