The specific drug, the amount taken, and how it was taken all determine the effect. The set, i.e. what the person expects and previous exposure of the body to this and other drugs, can alter effects. Guidelines for use Tranquillizers and sleeping pills are widely used prescription drugs. They are generally recommended for short-term treatment of anxiety and insomnia because they become less effective when taken for more than a few weeks or, at most, a few months. Also, tolerance can develop, so larger doses are required to achieve the same effect.
Dependence can also occur, making it difficult to discontinue use.
Tranquillizers and sleeping pills are drugs that are both misused and abused. People with a history of abusing alcohol or other drugs are particularly prone to having difficulty controlling their use of these drugs. Increasingly, doctors and their patients are seeking other ways to deal with stress and sleeplessness. Alternatives to drug use include exercise, biofeedback, relaxation techniques, and counselling. Toxic effects The effects of tranquillizers and sleeping pills include incoordination and impaired mental functioning.
