Valium is frequently prescribed by doctors as a sedative and a muscle relaxant. Taking Valium generally produces a soothing, calming effect. This pleasant feeling can be addictive over time, and the abuse of Valium was considered to be a wide-spread but silent problem during the 1980s.
Doctors freely prescribed Valium because it was thought to be non-addictive and is certainly non-toxic. But today, doctors tend to prescribe Valium and other depressants with more caution.

Valium is primarily a sedative and a muscle relaxant. It belongs to the benzodiazepine class of central nervous system depressants.
Valium has the interesting characteristic of a "flatter" dose-response slope than many other depressants. This refers to the speed and amount of effect the dosage of Valium has. Valium doesn't hit as hard, nor do its effects taper off as quickly, as similar drugs.
Valium is absorbed in the stomach and maximum effect takes place 1-2 hours after ingestion. Valium stays in the blood and has a half-life of 6-8 hours. Thus, it is a relatively long-term drug.
Valium is classed as a sedative-hypnotic drug. It has some or all of the following effects: sedative, disinhibitory, anticonvulsant, muscle relaxant, and hypnotic effects. As you can see from this list, Valium is an ideal treatment for anxiety and/or nervous tension.
Valium is non-toxic and cannot be used to commit suicide by deliberate overdose. When combined with other depressants, however, Valium could be fatal.
Doctors generally prescribe Valium for the management of mild to moderate anxiety or nervous tension. The following symptoms may be indicated: tension, excitation, agitation, fear or aggressiveness.
Valium is sometimes prescribed to counteract the tremors and agitation associated with acute alcoholic withdrawal.
Valium must be prescribed by a doctor. If you think you have a disorder or a complaint that requires Valium or a similar drug for treatment, talk to your doctor.
