It is part of a group of prescription drugs called benzodiazepines. Xanax is also a controlled drug, which means it has the potential to cause dependence or to be misused. These medications are regulated by law and it is illegal to take Xanax without a prescription from a medical doctor. Why Are Benzodiazepines Controlled Substances? Effects and Dosage The effects of Xanax depend on several factors. To ensure that you get the correct dose, you should clearly and honestly answer all of your doctor's questions. You need to take the Xanax dose exactly as prescribed. If you feel that your current dosage isn't having the intended effect, talk to your healthcare provider. The main effect of Xanax is feeling calmer. This effect can occur relatively quickly after the drug is taken. For people with anxiety disorders, taking Xanax can quickly offset the intense anxiety they experience (which can be debilitating). Xanax will make you feel calmer even if you do not have anxiety. This effect can attract people to misusing Xanax. The drug can also cause a pleasurable feeling or euphoria in some individuals, potentially contributing to abuse. Xanax is also available in an extended-release version called Xanax XR. There are several benefits to this version: Only one dose per dayReduced rebound effectPotential for decreased misuse Side Effects Xanax has many side effects. If you experience side effects, let your healthcare provider know. In some cases, you might need medical attention or a prescription for an alternative medication.

If you have been prescribed Xanax, it's very important for your safety and the safety of others that you do not drive or operate heavy machinery until you know how the drug makes you feel. Withdrawal As with other benzodiazepines, withdrawing from Xanax carries significant risks and should only be done under the supervision of a physician. Do not try to quit or cut down on Xanax without telling your healthcare provider—even if you have been taking a low dose or only taking the medication for a short time. The greatest risk of Xanax withdrawal is life-threatening seizures. How Long Does Benzodiazepine Withdrawal Last? Risks Xanax can interact with other drugs and medications. You should not take Xanax if you are taking another medication, including birth control, unless your provider has told you that it is safe. There are some medications or substances that you should never mix with Xanax, including ketoconazole, itraconazole, and alcohol. Herbs, nicotine, illicit drugs, dietary supplements, and non-prescription drugs all have the potential to be dangerous if taken with Xanax. You should not take Xanax with grapefruit and grapefruit juice, or herbal or dietary supplements such as kava kava, melatonin, dehydroepiandrosterone, DHEA, St. John's wort, and valerian. Xanax is not recommended if you are pregnant and/or breastfeeding. If you become pregnant while you are taking Xanax, contact your provider right away. An overdose of Xanax is a significant risk, especially for people who are not taking the medication as prescribed or are mixing it with other substances. Overdoses of medications like Xanax can be fatal and require immediate medical attention. If you or someone you love overdoses on Xanax, call 911 or go to the nearest emergency room. If you or a loved one are struggling with substance use 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.
