What is alprazolam?
Alprazolam is a benzodiazepine (ben-zoe-dye-AZE-eh-peen). Alprazolam affects chemicals in the brain that may be unbalanced in people with 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 is the most important information I should know about alprazolam?
You should not use this medicine if you have narrow-angle glaucoma, if you also take itraconazole or ketoconazole, or if you are allergic to alprazolam or similar medicines (Valium, Ativan, Tranxene, and others).
Do not use alprazolam if you are pregnant. This medicine can cause birth defects or life-threatening withdrawal symptoms in a newborn.
Alprazolam may be habit-forming. Misuse of habit-forming medicine can cause addiction, overdose, or death.
What should I discuss with my healthcare provider before taking alprazolam?
It is dangerous to purchase alprazolam on the Internet or from vendors outside the United States. Medications distributed from Internet sales may contain dangerous ingredients, or may not be distributed by a licensed pharmacy. The sale and distribution of alprazolam outside the U.S. does not comply with the regulations of the Food and Drug Administration (FDA) for the safe use of this medication.
You should not take alprazolam if you have:
if you are also taking itraconazole or ketoconazole; 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:
seizures or epilepsy;
kidney or liver disease (especially alcoholic liver disease);
asthma or other breathing disorder;
a history of depression or suicidal thoughts or behavior;
a history of drug or alcohol addiction; or
if you also use a narcotic (opioid) medication.
Do not use alprazolam if you are pregnant. This medicine can cause birth defects. Your baby could also become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant. Use effective birth control to prevent pregnancy while you are taking alprazolam.
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.
Alprazolam is not approved for use by anyone younger than 18 years old.
