Valium (diazepam), falls within the drug classification of benzodiazepines. Valium, along with the other benzodiazepines are by far the drugs most often prescribed to treat anxiety problems. Also in addition to being good for anxiety, Valium is frequently used as a muscle relaxant and for sleeping difficulties. Sometimes the benzodiazepines are also used to treat seizures in some patients with epilepsy. It is considered a long-acting benzodiazepine, in that you may take one dosage to last all day. Valium is frequently prescribed for individuals with generalized anxiety disorder, problems with muscle relaxation (such as if you have back problems), and even for a condition called night terrors that occurs with children.

How Does Diazepam Work?
Valium (diazepam) produces depression in the central nervous system. It contains anticonvulsant, amnesic, anxiolytic, sedative and muscle relaxant properties. Valium also affects areas on the limbic system, the thalamus and hypothalamus contributing to the relief of anxiety. Valium is long lasting and can be given intravenously, orally, intra muscularly and also as a rectal suppository. Due to Valium producing dependence and tolerance, short term use is recommended.

However, these side effects are not common when taking diazepam.
