What Are the Withdrawal Symptoms of Nembutal?  

Nembutal (phenobarbital) is a drug that belongs to the barbiturate class.

Barbiturates are central nervous system depressants that were originally designed to treat individuals who had severe anxiety, seizures, and issues with sleep. They are also sometimes still used as preanesthetic agents.

Barbiturates are classified as controlled substances by the United States Drug Enforcement Administration. Nembutal is classified as a Schedule II substance, meaning it has medicinal uses but is also a very strong candidate for the development of physical dependence and for abuse.

Withdrawal Syndrome

A withdrawal syndrome or discontinuation syndrome occurs in a person has developed physical dependence on a specific drug. Physical dependence occurs as a result of the development of both tolerance to the drug and a withdrawal syndrome.

Tolerance refers to the experience of no longer getting the effects from a particular amount or dose of a drug that one has been taking over a period of time. The individual’s system has become habituated to the drug, and the person needs to use more of the drug to get the same effects that they previously got at lower doses. Individuals who abuse drugs are often using them for their psychoactive (mind-altering) effects, and the development of tolerance becomes a nuisance to them. They will begin to take extreme doses of the drug to get the effects that they got when they initially began taking the drug. In the case of Nembutal, this can result in taking doses that would be dangerous or even fatal to other individuals who have not developed the same level of tolerance.

As tolerance develops, an individual’s system will begin to adjust itself to the presence of Nembutal in its tissues. It will alter certain aspects of its functioning, such as its production of hormones and neurotransmitters, to compensate for the drug being in the system. As time goes on and the person continues to use increasingly higher doses of the drug, the system has adjusted to the point where it can no longer function optionally without the drug in its tissues. When the person cannot use the drug or cuts down the dosage, the system is thrown out of balance, and the person experiences a number of very unpleasant physical and emotional side effects.

When an individual has developed both tolerance and withdrawal, they become physically dependent on the drug and can only operate or function normally when the drug is in their system at a specific level.

While the development of physical dependence can be a sign of addiction, physical dependence is not necessarily a sign that one has developed a substance use disorder. For example, a person with a severe seizure disorder, such as an individual who has epilepsy, may be prescribed regular doses of Nembutal and, over time, may develop physical dependence on the drug. However, as long as the person takes the drug as prescribed (for medicinal uses and under the supervision of a physician), they would not receive a diagnosis of a substance use disorder.

Substance use disorders occur when individuals use drugs for nonmedicinal reasons, have issues with control of their use, and continue using drugs despite experiencing a number of negative ramifications.
