This may not be a complete list of all interactions that may occur. Ask your health care provider if Xanax may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

How to use Xanax:

Use Xanax as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • Xanax may be taken with or without food. If stomach upset occurs, take with food to reduce stomach irritation.
  • If you are taking Xanax regularly, do not suddenly stop taking it without checking with your doctor. You may have an increased risk of side effects, including seizure. If you need to stop Xanax, your doctor will gradually lower your dose.
  • Check with your doctor before eating grapefruit or drinking grapefruit juice while you use Xanax.
  • If you miss a dose of Xanax and you are using it regularly, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use Xanax.

Important safety information:

  • Xanax may cause drowsiness, dizziness, light-headedness, or blurred vision. Do not drive, operate machinery, or do anything else that could be dangerous until you know how you react to Xanax. Using Xanax alone, with certain other medicines, or with alcohol may lessen your ability to drive or to perform other potentially dangerous tasks.
  • Do not drink alcohol while you are using Xanax.
  • Check with your doctor before you use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using Xanax; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
  • Do not take more than the recommended dose or use for longer than prescribed without checking with your doctor.
  • Smoking may decrease Xanax's effectiveness. Tell your doctor if you smoke or if you have recently stopped smoking.
  • Tell your doctor or dentist that you take Xanax before you receive any medical or dental care, emergency care, or surgery.
  • Use Xanax with caution in the ELDERLY; they may be more sensitive to its effects, especially decreased coordination and drowsiness.
  • Xanax should be used with extreme caution in CHILDREN younger than 18 years old; safety and effectiveness in these children have not been confirmed.
  • PREGNANCY and BREAST-FEEDING: Xanax may cause harm to the fetus. If you think you may be pregnant, discuss with your doctor the benefits and risks of using Xanax during pregnancy. Xanax is found in breast milk. Do not breast-feed while taking Xanax.

When used for long periods of time or at high doses, Xanax may not work as well and may require higher doses to obtain the same effect as when originally taken. This is known as TOLERANCE. Talk with your doctor if Xanax stops working well. Do not take more than prescribed.

Some people who use Xanax may develop a need to continue taking it. People who take higher doses (eg, some patients with panic disorder) or use Xanax for a long time have a greater risk. This is known as DEPENDENCE or addiction. If you stop taking Xanax suddenly, you may have WITHDRAWAL symptoms. These may include blurred vision; burning, numbness, or tingling; changes in smell or other senses; decreased appetite; decreased awareness of your surroundings; decreased concentration; diarrhea; muscle cramps or twitches; seizures; or weight loss.
