Xanax Dosages, Side Effects, Risks, and Withdrawal

Xanax is the trade name for the anti-anxiety medication alprazolam. 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.

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.

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 day
• Reduced rebound effect
• Potential 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.

• Allergic reactions (including skin rash, itching or hives, swelling of the face, lips, or tongue)
• Changes in appetite
• Changes in sex drive
• Confusion and forgetfulness
• Depression
• Difficulty sleeping
• Difficulty speaking
• Drowsiness
• Feeling faint or lightheaded (which can increase the risk of falls)
• Mood changes
• Trouble passing urine
• Feeling unusually weak or tired

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.

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.
