What Are the Side Effects of Xanax?

| last updated


Effects of Xanax Use

Xanax (alprazolam) belongs to a class of drugs called benzodiazepines. It is often prescribed to treat anxiety or panic disorders.

Xanax is sometimes abused because of its fast-acting, pleasantly calming effects. In fact, 6.6% of people aged 12 or older reported misusing alprazolam in the past year.1

Given that the drug can lead to tolerance, dependence, and addiction, it is important to understand all of the potential side effects of Xanax before using it.

Like other benzodiazepines, Xanax enhances the effect of GABA (gamma-aminobutyric acid), an inhibitory neurotransmitter in the brain. This depresses the central nervous system and slows down physical, mental, and emotional responses. The effects can last between 4 to 8 hours.3

Xanax’s effects will vary from person to person. Factors that influence Xanax’s effects include:

  • An individual’s physical condition, such as their height and weight.
  • Whether they mix Xanax with other drugs.
  • Whether the person has already developed a tolerance to the drug.

Xanax has a half-life of 6 to 26 hours depending on the dose. A half-life refers to the amount of time it takes for the body to get rid of half of the dose.2


Short-Term Effects

Xanax can also cause a number of unwanted side effects.

In most cases, the prescribing physician will discuss and go over what the person can expect when using the drug. The doctor will also take other factors into consideration, such as other medications the person is using. This will help them prescribe a safe and appropriate dose.

When someone buys or obtains Xanax without a doctor’s prescription or misuses it, they may experience harmful side effects because they may not know what dose they are taking or how it will interact with their body. This type of Xanax abuse also increases the risk of dependence and addiction.

Side effects of Xanax include: 5, 7

  • Nausea.
  • Constipation.
  • Dry mouth.
  • Fatigue.
  • Joint pain.
  • Headache.
  • Dizziness.

  • Changes in sex drive.

Long-Term Effects

Xanax is not intended for long-term use, and chronic use may indicate a substance use disorder. The prescribing doctor should re-evaluate a person’s condition after 4 months to determine if they need to continue taking Xanax.6

Studies have found impaired memory and visuospatial ability in long-term benzodiazepine users, and long-term users may experience cognitive deficits up to 6 months after stopping use.

Additionally, chronic users are at risk of accident or injury due to the drug’s effects on reaction time and driving skills.8,9 People who abuse Xanax may also exhibit disinhibited behavior such as getting into arguments or fights. 8,14

Long-term effects from using Xanax may include:8,9

  • Cognitive dysfunction.
  • Depression.
  • Delusions.
  • Hallucinations.
  • Impulsiveness.
  • Aggressive behavior.
  • Hostility.
  • Learning and memory problems.
  • Coordination problems.

Chronic Xanax abuse can also affect other aspects of a person’s life. In some cases, abuse of the drug may lead to: 14

  • Marital problems.
  • Missed time from work.
  • Relationship issues with family and close friends.
  • Neglecting family and work responsibilities.
  • Financial problems due to the expense of drug-seeking behavior.

Effects With Alcohol and Other Drugs

Mixing Xanax with other substances increases the risk of harmful side effects.

  • Mixing Xanax with alcohol – another central nervous system depressant – can lead to slowed or difficult breathing or liver damage, and places the user at an increased risk for overdose.15
  • People might use Xanax in combination with cocaine or amphetamines to help ease their “come down.” Alternatively, people may combine high doses of Xanax with methadone to “boost” its effects. 17
  • Using Xanax with opioids is especially dangerous, as it has the potential to enhance respiratory-depressant effects. This places the user at a much higher risk of overdose.18
  • Mixing Xanax with other medications can be fatal. For example, taking nefazodone (Serzone) can increase alprazolam levels.16

Tolerance, Dependence, and Addiction

Users can become dependent in as little as 2 weeks.


When a person takes Xanax for a prolonged period of time, their body can develop a tolerance. Tolerance can lead the person to take larger doses of Xanax or use it more often to achieve the desired effects.

As a person develops a tolerance to Xanax and takes more and more, their body quickly becomes dependent on the drug. Once dependence takes hold, a person’s system cannot function properly without it. Users can become physically and psychologically dependent on Xanax in as little as 2 weeks.6 Some users can even experience rebound or breakthrough anxiety after taking a dose.

Users who develop a dependence may experience withdrawal symptoms when they stop using. Dependence can also lead to Xanax addiction, which is characterized by compulsive use and continuing to use the drug despite negative consequences.
