What is the most important information I should know about alprazolam?

Multum nopreg

Do not use alprazolam if you are pregnant. It could harm the unborn baby.

Multum donot

Do not use this medication if you are allergic to alprazolam or to other benzodiazepines, such as chlordiazepoxide (Librium), clorazepate (Tranxene), diazepam (Valium), lorazepam (Ativan), or oxazepam (Serax).

Before you take alprazolam, tell your doctor if you have asthma or other breathing problems, glaucoma, kidney or liver disease, a history of alcoholism, or a history of depression, suicidal thoughts, or addiction to drugs or alcohol.

Multum noalcohol

Do not drink alcohol while taking alprazolam. This medication can increase the effects of alcohol.

Multum habit

Alprazolam may be habit-forming and should be used only by the person for whom it was prescribed. Keep the medication in a secure place where others cannot get to it.

What is alprazolam?

Alprazolam is a benzodiazepine (ben-zoe-dye-AZE-eh-peen). Alprazolam affects chemicals in the brain that may become unbalanced and cause anxiety.

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

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

What should I discuss with my healthcare provider before taking alprazolam?

Multum emt

It is dangerous to try and purchase alprazolam on the Internet or from vendors outside of the United States. Medications distributed from Internet sales may contain dangerous ingredients, or may not be distributed by a licensed pharmacy. Samples of alprazolam purchased on the Internet have been found to contain haloperidol (Haldol), a potent antipsychotic drug with dangerous side effects. For more information, contact the U.S. Food and Drug Administration (FDA) or visit www.fda.gov/buyonlineguide.

Multum donot

You should not take alprazolam if you have:

  • narrow-angle glaucoma;
  • if you are also taking itraconazole (Sporanox) or ketoconazole (Nizoral); or
  • if you are allergic to alprazolam or to other benzodiazepines, such as chlordiazepoxide (Librium), clorazepate (Tranxene), diazepam (Valium), lorazepam (Ativan), or oxazepam (Serax).

To make sure alprazolam is safe for you, tell your doctor if you have any of these conditions:

  • asthma, emphysema, bronchitis, chronic obstructive pulmonary disorder (COPD), or other breathing problems;
  • glaucoma;
  • kidney or liver disease (especially alcoholic liver disease);
  • a history of depression or suicidal thoughts or behavior; or
  • a history of drug or alcohol addiction.
Multum habit

Alprazolam may be habit forming and should be used only by the person for whom it was prescribed. Never share alprazolam with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.

Multum nopreg

FDA pregnancy category D. Do not use alprazolam if you are pregnant. It could harm the unborn baby. Alprazolam may also cause addiction or withdrawal symptoms in a newborn if the mother takes the medication during pregnancy. Use effective birth control, and tell your doctor if you become pregnant during treatment.

Multum nobrfeed

Alprazolam can pass into breast milk and may harm a nursing baby. You should not breast-feed while you are using alprazolam.

The sedative effects of alprazolam may last longer in older adults. Accidental falls are common in elderly patients who take benzodiazepines. Use caution to avoid falling or accidental injury while you are taking alprazolam.

Multum nochild

Do not give this medication to anyone under 18 years old.

How should I take alprazolam?

Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results.

Multum nocrush

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 alprazolam 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.

Do not swallow the orally disintegrating tablets whole. Allow it to dissolve in your mouth without chewing.

Multum emt

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

You may have seizures or withdrawal symptoms when you stop using alprazolam. Ask your doctor how to avoid withdrawal symptoms when you stop using alprazolam.

Keep track of the amount of medicine used from each new bottle. Alprazolam is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.

Multum rt

Store at room temperature away from moisture and heat.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Multum emt

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of alprazolam can be fatal. Overdose symptoms may include extreme drowsiness, confusion, muscle weakness, loss of balance or coordination, feeling light-headed, and fainting.

What should I avoid while taking alprazolam?

Multum noalcohol

Multum dizzy

Alprazolam may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.

Grapefruit and grapefruit juice may interact with alprazolam and lead to unwanted side effects. Discuss the use of grapefruit products with your doctor.
