Diazepam is a prescription medication that is used to treat anxiety, muscle spasms, and seizures. It belongs to a class of drugs known as benzodiazepines. Diazepam works by increasing the activity of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. GABA is involved in regulating the activity of nerve cells, and by increasing its activity, diazepam can help to reduce anxiety, muscle spasms, and seizures. Diazepam comes in tablet, capsule, and liquid forms, and is typically taken 2-4 times per day. The dosage is usually adjusted based on the individual's response to the medication and their medical condition. It is important to take diazepam exactly as prescribed and to follow the instructions of your healthcare provider.
