Anti-anxiety medications are one of the most common treatment options for panic disorder. Xanax (alprazolam) is one popular type of anti-anxiety medication that is often used in the treatment of panic disorder and other conditions.

What is Xanax?

Xanax is the trademark name for alprazolam, an anti-anxiety drug belonging to a group of medications known as benzodiazepines. These medications are also called tranquilizers due to their sedative and calming effects. Other commonly prescribed bezodiazepines include Klonopin (clonazepam), Valium (diazepam), and Ativan (lorazepam). Xanax can help reduce the severity of anxiety and panic attacks.

Xanax is primarily used for the treatment of panic disorder (with or without agoraphobia). It is often used in the treatment of other anxiety disorders, including generalized anxiety disorder, social anxiety disorder, and post-traumatic stress disorder (PTSD). Xanax can also be prescribed for the treatment of seizures, sleep disturbances, depression, bipolar disorder, and other conditions.

How Does Xanax Treat Panic Disorder?

Like other benzodiazepines, Xanax impacts the gamma-aminobutyric acid (GABA) receptors, a neurotransmitter in the brain that is involved in sleep regulation, relaxation, and anxiety. This action can assist in slowing down the central nervous system (CNS), decreasing agitation and over-excitement while creating a tranquilizing or relaxing effect. Depressing the central nervous system also helps alleviate feelings of anxiety and lessen the severity of panic attacks. Xanax typically produces fast-acting results, rapidly eliciting feelings of calm and quickly decreasing panic disorder symptoms. Xanax has a short half-life, meaning it gets in and out of your system quickly. This has advantages and drawbacks, including the fact that you have to take it frequently, and it may result in ups and downs in anxiety control in some people.

What Are the Side Effects of Xanax?

Some of the most common side effects of Xanax include:

  • Drowsiness
  • Dry mouth
  • Dizziness and lightheadedness
  • Lack of coordination or unsteadiness
  • Slurred speech
  • Confusion
  • Memory impairment

Is Xanax Addictive?

As controlled substances, all benzodiazepines, including Xanax, have the potential to be both physically and emotionally addictive, and can be abused. It can be hard to discontinue Xanax if a dependence to the drug develops, as a person may experience withdrawal symptoms. Some typical withdrawal symptoms include increased anxiety, tremors, sleep disturbances, fatigue, difficulty concentrating, and muscle pain or tension.

To minimize the risk of addiction, Xanax is often prescribed for a limited period of time. Your doctor may regulate your prescription by only providing a certain amount of medication so that your condition can be periodically reevaluated before continuing on Xanax. Never increase or decrease your dosage without first consulting your doctor. To prevent withdrawal symptoms, your doctor may gradually reduce your dosage.

What Other Precautions Are There to Taking Xanax?

There are several precautions and contraindications to consider when taking Xanax:

Medical History: Caution should be taken if you have a history of certain medical conditions. Consult your doctor before taking Xanax if you have been diagnosed with these or any other medical condition:

Drug Interactions: Xanax slows down the central nervous system. A person may experience side effects when taking Xanax with certain other medications that similarly depress the central nervous system. These symptoms may include increased depression, sleep issues, or extreme fatigue. Alcohol should also be avoided. Before starting on Xanax, tell your doctor if you are taking any prescribed or over-the-counter medications.

Pregnancy and Nursing: It is possible for Xanax to be passed to a child during pregnancy or while breastfeeding. Talk to your doctor about the risk of using Xanax while pregnant or nursing.

Older Adults: Older adults are often more susceptible to the effects of Xanax. Prescribing doctors may need to adjust dosage to assist in limiting these effects.
