"Following the use of substance intoxication or withdrawal, may come:prominent anxiety, panic attacks, obsessions or compulsions."
from Diagnostic and Statistical Manual of Mental Disorders , ( DSM-IV-TR )Prominent anxiety, panic attacks, or obsessions and compulsions. Symptoms develop during, or within one month of intoxication or withdrawal from a substance Symptoms are not actually part of another disorder that is substance induced. For instance, if anxiety the symptoms began prior to substance or medication use, than another disorder is likely. Symptoms do not occur only during delirium Symptoms cause significant distress or impairment in functioning. Read More: Click Here
The disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.

A substance-induced anxiety disorder is caused by the effects of drugs. This can include, alcohol, medications and toxins. Anxiety symptoms arise from being intoxicated on all different type of substances. Anxiety can also arise from withdrawal of these substances.
Types of Drugs That May Cause Anxiety:
Antipsychotic medications
Nerve gases
Carbon Monoxide
There are many different types of drugs that can affect the nervous system and contribute to anxiety.

SpecifiersWith Generalized AnxietyThis specifier may be used if excessive anxiety or worry about a number of events oractivities predominates in the clinical presentation.
With Panic AttacksThis specifier may be used if Panic Attacks predominate in the clinical presentation.
With Obsessive-Compulsive SymptomsThis specifier may be used if obsessions or compulsions predominate in the clinical presentation.
With Phobic SymptomsThis specifier may be used if phobic symptoms predominate in the clinical presentation.
The development of the anxiety symptoms may be indicated by using one of the following specifiers:With Onset During IntoxicationThis specifier should be used if criteria for intoxication with the substance are met andthe symptoms develop during the intoxication syndrome.
With Onset During WithdrawalThis specifier should be used if criteria for withdrawal from the substance are met and the symptomsdevelop during, or shortly after, a withdrawal syndrome.

Diagnosis & Treatment

Medical conditions in Substance Induced Anxiety Disorders are what cause the anxiety in the first place, so to deal with this the
patient must be taking medication to deal with the medical problem. Than a diagnosis of the anxiety disorder can be made.
Clinical history and physical examinations are best to identify the anxiety disorder, but complete blood counts,
chemistry panels, and urine screens for drugs also work.


The cause of anxiety symptoms can determine what is needed for treatment. Treatment can often be similar to thoseused to treat generalized anxiety disorders, phobias, panic disorders, or even obsessive-compulsive disorders.Most all treatments work most effectively with medications.

Other Facts
The essential features of Substance-Induced Anxiety Disorder are prominent anxiety symptoms (Criterion A) that are judged to be due to the direct physiological effects of a substance (i.e., a drug of abuse, a medication, or toxin exposure) (Criterion B). Depending on the nature of the substance and the context in which the symptoms occur (i.e., during intoxication or withdrawal), the disturbance may involve prominent anxiety, Panic Attacks, phobias, or obsessions or compulsions. Although the clinical presentation of the Substance-Induced Anxiety Disorder may resemble that of Panic Disorder, Generalized Anxiety Disorder, Social Phobia, or Obsessive-Compulsive Disorder, the full criteria for one of these disorders need not be met. The disturbance must not be better accounted for by a mental disorder (e.g., another Anxiety Disorder) that is not substance induced (Criterion C). The diagnosis is not made if the anxiety symptoms occur only during the course of a delirium (Criterion D). The symptoms must cause clinically significant distress or impairment in social, occupational, or other important areas of functioning (Criterion E). This diagnosis should be made instead of a diagnosis of Substance Intoxication or Substance Withdrawal only when the anxiety symptoms are in excess of those usually associated with the intoxication or withdrawal syndrome and when the anxiety symptoms are sufficiently severe to warrant independent clinical attention. For a more detailed discussion of Substance-Related Disorders, see .

A Substance-Induced Anxiety Disorder is distinguished from a primary Anxiety Disorder by considering the onset, course, and other factors. For drugs of abuse, there must be evidence from the history, physical examination, or laboratory findings of Dependence, Abuse, intoxication, or withdrawal.

Substance-Induced Anxiety Disorders arise only in association with intoxication or withdrawal states, whereas primary Anxiety Disorders may precede the onset of substance use or occur during times of sustained abstinence. Because the withdrawal state for some substances (e.g., some benzodiazepines) can be relatively protracted, the onset of the anxiety symptoms can occur up to 4 weeks after cessation of substance use but is usually earlier. This information was received from the Diagnostic and Statistical Manual of Mental Disorders.
