Clinicians also prescribe it off-label to treat depression. Benzodiazepines are sedatives that typically produce feelings of relaxation or sleepiness. Like all medications, Xanax can cause side effects, which may include: Changes in appetiteDizziness or light-headednessDrowsinessDry mouthHeadacheIrritabilityJoint painProblems concentratingTiredness For people with generalized anxiety disorder, Xanax is commonly prescribed alongside an antidepressant to relieve the nervousness that antidepressants initially cause in some people. Experts do not recommend using Xanax for an extended time. Like other benzodiazepines, Xanax can be habit-forming. You may become dependent on this medication, even if you take it exactly as prescribed. If you're taking Xanax, be aware of the potential side effects, and know when to contact your doctor or healthcare professional. Common Xanax Side Effects Xanax is one of the most commonly prescribed benzodiazepines in the United States. However, many side effects are associated with it, including: Drowsiness or fatigue Dizziness Dysarthria (slurred or slow speech) Headache Memory impairment Depression Although mild side effects are common, keep a close eye on any you experience, and stay in contact with your healthcare professional, Severe Side Effects You shouldn't use benzodiazepines for more than two to four weeks. Chronic, long-term use of Xanax risks serious effects and health issues, including: Decreased motor coordination Impaired concentration Memory loss Poor reaction time Slower processing of information Loss of sex drive Increased anxiety and depression If you experience any of these, contact your healthcare provider immediately. Never stop taking Xanax on your own; it has the most severe withdrawal effects of all benzodiazepines. Instead, speak with your clinician about tapering off Xanax gradually to avoid serious withdrawal effects. Benzodiazepine withdrawal can be life-threatening and must be supervised by a trained medical professional. Potential for Addiction One study found that, after four to eight months of treatment with benzodiazepines, 40% of patients became dependent on them. Xanax falls into this category and thus poses a risk for addiction. The problem typically arises when a patient develops a tolerance to the drug over time. The Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR) lists the following as the criteria for drug tolerance: You feel diminished effects of a drug over time when taking the same amount.You require larger amounts of the drug over time to feel the same effects. Because this tolerance might compel you to increase your dose, Xanax can be highly addictive. Xanax has a high "misuse liability," meaning individuals often develop a physical dependence on it. Those who chronically use benzodiazepines such as Xanax non-orally (such as via injection) experience significant respiratory distress and a tranquilizing effect on the central nervous system (CNS). If you or a loved one are dealing with substance abuse or addiction, contact the Substance Abuse and Mental Health Services Administration (SAMHSA) National Helpline at 1-800-662-4357 for information on support and treatment facilities in your area. For more mental health resources, see our National Helpline Database. Xanax Warnings and Interactions Before taking Xanax, tell your doctor about pre-existing health conditions, any history with addiction, and other medications you're taking. Liver Function Xanax is metabolized by the liver. If you have liver disease or your liver isn't fully functioning, you must be closely monitored for liver damage while taking Xanax. Your doctor might order a blood test to measure your liver function before you start Xanax, or might choose not to prescribe it for you at all. Substance Use Disorder Given Xanax's high potential for misuse and/or addiction, it's important to consult your doctor before taking it if you have a substance use disorder or a history of substance misuse. Those with substance use disorders may be at higher risk of developing an addiction to Xanax. People who are withdrawing from opiates sometimes self-medicate with Xanax. Likewise, people with addictions to other benzodiazepines such as Valium (diazepam) and Ativan (lorazepam) are also more likely to misuse Xanax because they produce a similar sedating effect. Misusing Xanax or mixing it with other substances has life-threatening consequences, including overdose. Be sure to talk to a healthcare professional before taking Xanax with other substances to avoid potentially dangerous drug interactions. People Over Age 65 People over age 65 should exercise caution when taking Xanax. Older adults have a greater risk for negative side effects, particularly if they combine Xanax with other medications affecting the central nervous system. These effects include: Unsteady gaitMemory problemsLoss of balanceCognitive impairmentRisk of fallingRisk of motor vehicle collision If you're an older adult, your doctor or healthcare professional should monitor you closely if you're taking Xanax. Pregnancy and Breastfeeding Xanax can harm a developing fetus if taken during pregnancy. Potential effects include: Respiratory and feeding difficultyConvulsionsHypotonia (floppy baby syndrome)Neonatal drowsinessLow birth weightIrritabilityWithdrawal symptoms High doses of Xanax taken in the third trimester are associated with fetal benzodiazepine syndrome. This includes floppy baby syndrome, withdrawal symptoms, and problems regulating temperature. Breastfeeding isn't recommended while taking Xanax or other benzodiazepines. An infant can be exposed to Xanax through breast milk. The potential side effects in a baby include sedation, poor temperature regulation, and lethargy. Other Medications Do not take Xanax with other CNS depressants, such as Valium, Klonopin (clonazepam), alcohol, barbiturates, tricyclic and tetracyclic drugs, dopamine receptor antagonists, opioids, and antihistamines. This can result in excessive sedation, respiratory depression, and in some cases, overdose. If you or someone you're with is experiencing side effects from mixing Xanax and other substances, dial 911 and request an ambulance. The person's healthcare provider should be notified that they are in the emergency room. Effects of Xanax Withdrawal One found that after six months of treatment, 40% of people taking benzodiazepines have moderate to severe withdrawal symptoms once they quit taking the medication. Common effects of withdrawal include: Malaise Dizziness Insomnia Tachycardia (fast heart rate) Severe sleep disturbance Rebound Effects Though tapering off Xanax may help with the intensity of withdrawal, certain symptoms are still common when you discontinue Xanax. Patients who experienced anxiety prior to starting Xanax may feel more anxious after stopping it. This is known as "rebound anxiety." One study found that 15 out of 17 patients with panic disorder experienced a "reoccurrence or increase" in their panic attacks after tapering off Xanax. Similarly, people with post-traumatic stress disorder (PTSD) who gradually discontinued Xanax experienced effects such as irritability, nightmares, worsened anxiety, hyper-alertness, rage, and homicidal ideation. Multiple case studies have reported delirium and psychosis in patients who discontinued Xanax. These withdrawal effects have not been linked to any other benzodiazepine. If you have experienced these or any other concerning side effects as a result of withdrawing from Xanax, seek medical attention right away. Tapering Off Xanax Tapering off a drug means that you gradually reduce the dosage until you stop taking it altogether. This process can help minimize the severity of withdrawal effects. Consult with your doctor if you are tapering off Xanax; they will provide you with specific instructions on how to do so safely. Generally, you can expect to decrease your Xanax dosage by no more than 0.5 mg every three days. Effects of Xanax Overdose Overdose can happen when a person takes larger doses of Xanax than prescribed, they take it more frequently than prescribed, they inject the drug, and/or they mix it with other CNS depressants. Signs of an overdose vary with the person. However, the following are common: Trouble breathingConfusionDizzinessBlurred visionImpaired motor skillsBluish lips or fingernailsTremorsComa Other serious complications from overdose include pneumonia, muscle damage, brain damage, and even death. If you or someone you know is experiencing signs of overdose from Xanax, call 911 immediately. Anyone experiencing an overdose requires immediate medical attention. Once at the hospital or with emergency services, they are often given intravenous fluids, respiratory support, and/or medications to help combat the effects. Treatment and Recovery for Xanax Addiction If you think you might be dependent or addicted to Xanax, treatments are available that can help. Talk to your doctor about a tapering schedule that will help you stop using Xanax. In some instances, your doctor may recommend switching to a longer-acting benzodiazepine in conjunction with tapering to help manage withdrawal symptoms. Next, discuss your options for long-term treatment. Treatments for Xanax addiction typically focus on the use of cognitive behavioral therapy (CBT) to help people change thoughts and behaviors that influence substance use. Therapy can also help people develop healthier coping mechanisms for managing life's stresses. There are also self-help strategies you can use to care for yourself while you are recovering. To aid in recovery and prevent relapse: Seek support from friends and family Avoid triggers that can contribute to cravings and drug use Get regular exercise Build healthy habits, such as eating a balanced diet and getting enough sleep Find ways to stay busy Engage in hobbies and activities that you enjoy Utilize relaxation techniques such as deep breathing and mindfulness meditation to manage stress You might also consider joining a support group. Such groups can be a great way to get support and encouragement from others who have faced similar challenges. Frequently Asked Questions How long do side effects of Xanax last? You'll feel the effects of Xanax in about 10 minutes to an hour after taking a dose, and they'll peak by the two-hour mark and subside by four. However, Xanax remains in your system for about 11 hours, so you can feel side effects during this time. Does Xanax cause headaches? You might experience headaches while taking Xanax, after taking it, or as you taper off of it. Some people report a hangover-like feeling after taking Xanax. How do you quit Xanax without side effects? Don't stop taking Xanax suddenly. Instead, consult your healthcare provider before quitting it. They will show you how to safely taper down your dosage gradually to minimize withdrawal effects. 12 Sources Verywell Mind uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles.
