What is Xanax?

Xanax is in a group of drugs called benzodiazepines (ben-zoe-dye-AZE-eh-peens). Alprazolam affects chemicals in the brain that may become unbalanced and cause anxiety.

Xanax is used to treat anxiety disorders, panic disorders, and anxiety caused by depression.

Xanax may also be used for other purposes not listed in this medication guide.

How should I take Xanax?

Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.

Your doctor may occasionally change your dose to make sure you get the best results from this medication.

Xanax may be habit-forming and should be used only by the person it was prescribed for. Alprazolam should never be shared with another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it.

Do not crush, chew, or break an extended-release tablet. Swallow the pill whole. It is specially made to release medicine slowly in the body. Breaking the pill would cause too much of the drug to be released at one time.

Measure the liquid form of Xanax with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.

To take Xanax orally disintegrating tablets (Niravam):

  • Using dry hands, remove a tablet from the bottle and place the tablet on your tongue. It will begin to dissolve right away.
  • Do not swallow the tablet whole. Allow it to dissolve in your mouth without chewing.
  • Swallow several times as the tablet dissolves. If desired, you may drink liquid after the tablet has completely dissolved.

Contact your doctor if this medicine seems to stop working as well in treating your panic or anxiety symptoms.

Your symptoms may return when you stop using Xanax after using it over a long period of time. You may also have seizures or withdrawal symptoms when you stop using alprazolam. Withdrawal symptoms may include blurred vision, trouble concentrating, loss of appetite, diarrhea, muscle twitching, numbness or tingling, or increased sensations.

Do not stop using Xanax suddenly without first talking to your doctor. You may need to use less and less before you stop the medication completely.

To be sure this medication is helping your condition, your doctor will need to check your progress on a regular basis. Do not miss any scheduled visits to your doctor.

Store Xanax at room temperature away from moisture, heat, and light. Remove any cotton from the bottle of disintegrating tablets, and keep the bottle tightly closed.

Keep track of how many pills have been used from each new bottle of this medicine. Benzodiazepines are drugs of abuse and you should be aware if any person in the household is using this medicine improperly or without a prescription.

What happens if I miss a dose?

Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at your next regularly scheduled time. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention if you think you have used too much of this medicine. An overdose of Xanax can be fatal.
