Xanax is a tranquilizer used in the short-term relief of symptoms of anxiety or the treatment of anxiety disorders. Anxiety disorder is marked by unrealistic worry or excessive fears and concerns.

Xanax is also used in the treatment of panic disorder, which appears as unexpected panic attacks and may be accompanied by a fear of open spaces called agoraphobia. Only your doctor can diagnose panic disorder and best advise you about treatment. Anxiety associated with depression is also responsive to Xanax.

Some doctors prescribe Xanax to treat alcohol withdrawal, fear of open spaces and strangers, depression, irritable bowel syndrome, and premenstrual syndrome.
Tolerance and dependence can occur with the use of Xanax. You may experience withdrawal symptoms if you stop using the drug abruptly.

Only your doctor should advise you to discontinue or change your dose.
Xanax may be taken with or without food. Take it exactly as prescribed.

* If you miss a dose...

If you are less than 1 hour late, take it as soon as you remember. Otherwise skip the dose and go back to your regular schedule. Never take 2 doses at the same time.

* Storage instructions...

Store Xanax at room temperature.
Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking Xanax. Your doctor should periodically reassess the need for this drug.

If you are sensitive to or have ever had an allergic reaction to Xanax or other tranquilizers, you should not take this medication. Also avoid Xanax while taking the antifungal drugs Sporanox or Nizoral. Make sure that your doctor is aware of any drug reactions that you have experienced.

Do not take this medication if you have been diagnosed with the eye condition called narrow-angle glaucoma.

Anxiety or tension related to everyday stress usually does not require treatment with Xanax. Discuss your symptoms thoroughly with your doctor.
Xanax may cause you to become drowsy or less alert; therefore, driving or operating dangerous machinery or participating in any hazardous activity that requires full mental alertness is not recommended.

If you are being treated for panic disorder, you may need to take a higher dose of Xanax than for anxiety alone. High doses--more than 4 milligrams a day--of this medication taken for long intervals may cause emotional and physical dependence. It is important that your doctor supervise you carefully when you are using this medication.

Remember that withdrawal symptoms can occur when Xanax is stopped suddenly.
Xanax may intensify the effect of alcohol. Do not drink alcohol while taking this medication.

Never combine Xanax with Sporanox or Nizoral. These drugs cause a buildup of Xanax in the body.
