Drug Detail:Alprazolam (Alprazolam)
Generic Name: alprazolam [ al-PRA-zoe-lam ]
Drug Class: Benzodiazepines
Risks from Concomitant Use with Opioids; Abuse, Misuse, and Addiction and Dependence and Withdrawal Reactions
Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs for patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation.
The use of benzodiazepines, including alprazolam, exposes users to risks of abuse, misuse, and addiction, which can lead to overdose or death. Abuse and misuse of benzodiazepines commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with an increased frequency of serious adverse outcomes. Before prescribing alprazolam and throughout treatment, assess each patient's risk for abuse, misuse, and addiction.
The continued use of benzodiazepines, including alprazolam, may lead to clinically significant physical dependence. The risks of dependence and withdrawal increase with longer treatment duration and higher daily dose. Abrupt discontinuation or rapid dosage reduction of alprazolam after continued use may precipitate acute withdrawal reactions, which can be life-threatening. To reduce the risk of withdrawal reactions, use a gradual taper to discontinue alprazolam or reduce the dosage .
Uses for alprazolam
Alprazolam is used to relieve symptoms of anxiety, including anxiety caused by depression. It is also used to treat panic disorder in some patients.
Alprazolam is a benzodiazepine. Benzodiazepines belong to the group of medicines called central nervous system (CNS) depressants, which are medicines that slow down the nervous system.
This medicine is available only with your doctor's prescription.

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Appropriate studies have not been performed on the relationship of age to the effects of alprazolam in the pediatric population. Safety and efficacy have not been established.
Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of alprazolam in the elderly. However, elderly patients are more likely to have unwanted effects (eg, severe drowsiness, dizziness, confusion, clumsiness, or unsteadiness) and kidney, liver, or lung problems, which may require caution and an adjustment in the dose for patients receiving this medicine.

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Precautions while using alprazolam
It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly. Blood and urine tests may be needed to check for any unwanted effects.
Tell your doctor if you are pregnant or planning to become pregnant. Using this medicine during the later pregnancy may cause problems in your newborn baby (eg, sedation or withdrawal symptoms). Tell your doctor right away if your baby has an abnormal sleep pattern, diarrhea, feeding problems, a high-pitched cry, irritability, low muscle tone, restlessness, shakiness or tremors, sluggishness, trouble breathing, weight loss, vomiting, or fails to gain weight. If you think you have become pregnant while using the medicine, tell your doctor right away.
Do not take itraconazole (Sporanox®) or ketoconazole (Nizoral®) while you are using this medicine. Using any of them together with this medicine may increase the chance of serious side effects.
This medicine will add to the effects of alcohol and other CNS depressants (medicines that slow down the nervous system, possibly causing drowsiness). Some examples of CNS depressants are antihistamines or medicine for hay fever, allergies, or colds, sedatives, tranquilizers, or sleeping medicine, prescription pain medicine or narcotics, barbiturates or seizure medicines, muscle relaxants, or anesthetics (numbing medicines), including some dental anesthetics. This effect may last for a few days after you stop using this medicine. Check with your doctor before taking any of the above while you are using this medicine.
If you develop any unusual and strange thoughts or behavior while you are taking alprazolam, be sure to discuss it with your doctor. Some changes that have occurred in people taking this medicine are like those seen in people who drink alcohol and then act in a manner that is not normal. Other changes may be more unusual and extreme, such as confusion, worsening of depression, hallucinations (seeing, hearing, or feeling things that are not there), suicidal thoughts, and unusual excitement, nervousness, or irritability.
Alprazolam may cause some people, especially older persons, to become drowsy, dizzy, or less alert than they are normally. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy, or are not alert or able to see well.
Do not change your dose or stop taking this medicine without checking first with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help prevent a worsening of your condition and reduce the possibility of withdrawal symptoms including changes in behavior, discouragement, feeling sad or empty, irritability, lack of appetite, loss of interest or pleasure, nausea or vomiting, seeing or hearing things that others do not see or hear, seizures or tremors, stomach or muscle cramps, sweating, thoughts of killing oneself, trouble concentrating, trouble sleeping, unusual movements, responses, or expressions.
This medicine may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.
Symptoms of an overdose include: change in consciousness, confusion, dizziness, faintness, or lightheadedness when getting up suddenly from a lying or sitting position, drowsiness, hallucinations, lack of coordination, loss of consciousness, loss of strength or energy, muscle pain or weakness, shakiness and unsteady walk, sleepiness, trouble in speaking, trouble sleeping, unsteadiness, trembling, or other problems with muscle control or coordination, unusual excitement, nervousness, restlessness, or irritability, or unusual weakness.
