Alprazolam (Xanax®)

This article provides a comprehensive overview of alprazolam, including how it works, the conditions it’s used for, side effects, interactions, and precautions. It also covers important information about the potential for misuse, dependence, and addiction with alprazolam.

Key Takeaways:

• Alprazolam is a benzodiazepine medication used primarily for anxiety and panic disorders. It works by increasing the effects of GABA, which relaxes the mind and body via its effects on the nervous system.
• Alprazolam works rapidly, but also may cause dependence and addiction, even when it is used as prescribed. Because of this, alprazolam is mainly recommended for short-term use, although it may be deemed necessary in some cases of chronic anxiety and panic disorders.
• Alprazolam interacts with many other medications, and has potentially dangerous and life-threatening effects when combined with alcohol and certain medications that slow down the nervous system.

Understanding Alprazolam

Alprazolam is a prescription anti-anxiety medication that belongs to the class of medications called benzodiazepines. It produces calming effects in the brain and nervous system, which is why it’s often used for panic and anxiety. Alprazolam may also be used for other symptoms and mental health conditions as well, such as insomnia. ^[1]

How it Works

Alprazolam works by reducing overactivity in the brain and nervous system. Specifically, alprazolam increases the activity of GABA, which is a neurotransmitter that offers inhibitory effects in the central nervous system (CNS), leading to decreased mental activity and muscle relaxation. In turn, this helps to control the symptoms of panic and anxiety, such as racing thoughts, worry, muscle tension, and rapid heart rate. ^{[1] [2]}

Brand Names

The most common brand name of alprazolam is Xanax®.

Other brand names of alprazolam include: ^[3]

• Niravam
• Xanax XR®

There are many other brand names for alprazolam that vary depending on which country you are in.

Conditions Alprazolam is Used For

Alprazolam is approved for the treatment of certain anxiety-related conditions, including: ^{[1] [2]}

• Generalized anxiety disorder (GAD)
• Panic disorder, with or without agoraphobia

GAD involves excessive or unrealistic anxiety or worry about certain life circumstances, which lasts longer than 6 months. Other symptoms include restlessness, muscle tension, trouble sleeping, difficulty concentrating, and being easily startled, among others.

Panic disorder involves recurrent, unexpected panic attacks, which are characterized by intense feelings of fear and/or discomfort. They often involve pounding heart rate, shortness of breath, chest pain, dizziness, a sense of being detached from one’s body, and a fear of dying, among other symptoms.

Alprazolam has been clinically researched to help with these conditions, in which it controlled symptoms significantly better compared to placebo. ^[2]

Off-Label Uses

Alprazolam is also used off-label for several conditions and symptoms, including: ^{[1] [4]}

• Insomnia
• Depression (Particularly symptoms of anxiety that are involved with or caused by depression)
• Premenstrual syndrome
• Agoraphobia (which is an intense fear of situations where escape or help feels impossible, often leading to avoiding public places or leaving home)

How Common is It?

Alprazolam is one of the most commonly prescribed mental health medications in the United States and worldwide, with millions of prescriptions being made annually. It accounts for over one-third of all benzodiazepine prescriptions in the United States. ^{[1] [5]}

Alprazolam Side Effects

There are many possible side effects of alprazolam. Common side effects of alprazolam include: ^{[1] [2] [3] [4]}

• Drowsiness
• Tiredness
• Dizziness
• Decreased mental alertness
• Headache
• Nausea
• Vomiting
• Upset stomach
• Sleep problems
• Memory problems
• Diarrhea
• Blurred vision
• Increased sweating
• Changes in appetite
• Weight changes
• Swelling of hands or feet
• Dry mouth
• Stuffy nose

Other less common (but still reported) side effects of alprazolam are: ^{[1] [2]}

• Slurred speech
• Irritability
• Trouble concentrating
• Anorexia
• Issues with balance or coordination
• Fatigue
• Sedation
• Muscle weakness
• Jaundice
• Decreased libido/interest in sex

Make sure to tell your doctor as soon as possible if you experience any of these side effects. Some of these may require prompt medical attention.

Dangerous and Rare Side Effects

There are certain rare side effects to be aware of with alprazolam as well, some of which are dangerous and potentially life-threatening. This includes: ^{[1] [2] [4] [6]}

• Severe allergic reactions: Signs include hives, difficulty breathing, and swelling of the lips, tongue, face, or throat.
• Mania and hypomania: This involves periods of increased energy, abnormally elevated mood (sometimes with euphoria), racing thoughts, increased impulsivity, and other symptoms.
• Respiratory depression (slowed or shallow breathing): This results in decreased oxygen intake, which can be serious or even fatal in severe instances. This risk is greater when using an excessive dose or when combining alprazolam with other CNS depressants.
• Seizures
• Severe skin rash
• New or worsening depression
• Suicidal thoughts and behaviors
• Severe sedation or impaired coordination: This may increase the risk of falls, injuries, and accidents

If you have any signs of these side effects, report them to your doctor immediately.

Misuse, Dependence, and Addiction

Like other benzodiazepines, alprazolam has risks of misuse, dependence, and addiction. It is classified as a Schedule IV controlled substance under the Drug Enforcement Administration's (DEA’s) Controlled Substances Act. ^[2]

While short-term use of alprazolam is generally considered safe, long-term and consistent use may lead to physical dependence and addiction, even when used as prescribed. This risk increases with longer treatment time and higher daily doses, especially over 4mg per day. ^{[1] [2] [3]}

Furthermore, the risks are greater if alprazolam is misused, such as taking a higher dose than prescribed, or combining alprazolam with alcohol or other drugs, such as opioids, stimulants, and/or muscle relaxants. Taking these drugs/substances together is actually quite common and, especially when it involves opioids, accounts for many drug-related overdoses and deaths. ^[5]

There are several reasons why alprazolam has a higher potential for dependence and addiction. For example, it has a relatively short half-life, acts quickly, and increases dopamine significantly. It also produces hypnotic, sedative, and relaxation effects, which are all pleasant effects that can lead to drug cravings, especially when used recreationally. ^{[2] [7]}

Precautions

There are several important precautions with alprazolam, including the ones mentioned thus far. Alprazolam may hold greater risks when used in the following populations: ^{[1] [3] [4] [6]}

• Elderly adults: There is an increased risk of oversedation and risk of falls and injuries. Thus, a lower dose is needed, if it is used at all.
• Individuals with impairments in kidney, liver, or lung function: Use cautiously
• Obese individuals: May require a lower dose
• Pregnant and breastfeeding women: Use is not recommended
• Individuals with a current or history of severe depression/suicidal ideation:
• Alprazolam may increase the risk of suicide in these individuals

Also, alprazolam can cause significant drowsiness that may make it unsafe to drive, operate machinery, or perform complex tasks. Do not engage in any of these activities until you know how alprazolam affects you and after consulting with your doctor. ^[1]

Furthermore, alprazolam has a higher tendency than many other medications to produce emotional and physical dependence, which may also make it difficult to taper off or stop using. More information is included in the section below, “Alprazolam Cessation and Withdrawal”.

Drug Interactions

Alprazolam interacts with several other medications. Some interactions may be dangerous or even life-threatening.

Firstly, it is important to note that combining alprazolam with other drugs that depress CNS activity increases the risk of severe side effects, such as slow/shallowed breathing and severe drowsiness or dizziness. Examples of these drugs are: ^{[1] [2] [4] [6]}

• Other benzodiazepines (e.g. diazepam, lorazepam)
• Sleep medications (e.g., zolpidem, eszopiclone)
• Muscle relaxants (e.g., carisoprodol, cyclobenzaprine)
• Opioids (e.g., codeine, hydrocodone)
• Antihistamines (e.g., diphenhydramine)

Several other drugs and substances may interact with alprazolam, including: ^{[1] [2] [3] [4] [6]}

• Selective-serotonin reuptake inhibitors (SSRIs) (e.g., fluoxetine, fluvoxamine, sertraline)
• Tricyclic antidepressants (TCAs) (e.g., imipramine, desipramine)
• Other antidepressants, such as nefazodone
• Anti-seizure medications (e.g., carbamazepine, phenytoin)
• Certain antifungals (e.g., ketoconazole)
• Certain antibiotics (e.g., clarithromycin, erythromycin)

This list does not list all possible interactions. Be sure to tell your doctor all of the medications you currently take or have taken.

Other Interactions

In addition to medications, alprazolam may also interact with other substances, such as:

• Alcohol
• Marijuana
• Tobacco
• St. John’s wort
• Kava
• Grapefruit and grapefruit juice
• Caffeine

Of these, alcohol in particular poses a significant risk for CNS depression, which can cause slowed breathing, sleepiness, or coma or even death in severe instances. ^[2]

Alprazolam Dosage

Alprazolam is most often administered as an oral tablet, either as immediate-release (IR), disintegrating, or extended-release (XR) form. The IR and disintegrating forms are available in strengths of 0.25 mg, 0.5 mg, 1 mg, and 2 mg, while the ER tablets are available in strengths of 0.5 mg, 1 mg, 2 mg, and 3 mg. Alprazolam is also available as an oral solution, with strengths of 0.5 mg/5 mL and 1 mg/10 mL. ^{[1] [3]}

Listed below are the common dosages for the treatment of specific conditions: ^[1]

• Anxiety Disorders:
• Oral form: IR tablets, disintegrating tablets, and solution:
• Adult: Initial dose of 0.25 mg to 0.5 mg three times per day. Maximum dose of 4 mg/day
• Geriatric: 0.25 mg two or three times per day
• Panic Disorders:
• Oral form: XR tablets
• Adult: Initial dose of 0.5 mg to 1 mg once per day. Maintenance dose of 3 mg to 6 mg per day. Maximum dose of 10 mg/day.
• Geriatric: 0.5 mg once per day
• Oral form: IR tablets, disintegrating tablets, and solution:
• Adult: Initial dose of 0.5 mg three times per day. Maximum dose of 10 mg/day.
• Geriatric: 0.25 mg two to three times per day

Alprazolam Cessation and Withdrawal

Some individuals have significant difficulty stopping treatment with alprazolam due to its ability to create physical and psychological dependence, as well as addiction. It’s essential to come off of alprazolam only under medical supervision and guidance from your doctor. Suddenly stopping alprazolam can cause severe and potentially life-threatening withdrawal symptoms. ^[2]

Even when done under medical supervision, there is a risk of withdrawal symptoms when tapering off alprazolam. Lowering your dose of alprazolam may cause symptoms of anxiety and panic to reappear. Furthermore, you may experience new symptoms that may not have been present before. These are more indicative of true withdrawal and include: ^{[1] [2] [4]}

• Heightened sensory perception.
• Muscle cramps and twitching.
• Impaired concentration.
• Blurred vision.
• Decreased appetite.
• Weight loss.
• Insomnia.
• Paresthesias (e.g., skin tingling, numbness, prickling, or burning).
• Clouded thinking.

To help minimize or avoid these symptoms, your doctor will gradually reduce the dose of alprazolam over time. Typically, the dosage reduction is not by more than 0.5 mg every three days, and is often slower than this. More recent guidelines suggest a dose reduction of no more than 0.125mg weekly, with a total duration of at least 8 weeks. ^[7]

If you’ve been taking alprazolam for a long period of time, your doctor may also have you switch over to a longer-acting benzodiazepine to help reduce the chance of withdrawal side effects. ^{[1] [2]}

Alprazolam and Integrated Therapy

Alprazolam is primarily recommended for short-term use. Therefore, it is often combined with other forms of therapy, such as psychotherapy and other anti-anxiety treatments.

Psychotherapy offers many potential benefits because it helps individuals to better understand their thoughts, emotions, and behaviors, and leads to the development of key skills, such as emotional regulation, stress management, mindfulness, and cognitive restructuring. In turn, this can reduce anxiety and distress in daily life, improve overall functioning, and may minimize the need to rely on alprazolam for symptom relief.

Alprazolam is also sometimes combined with other mental health medications such as SSRIs. SSRIs are considered safer and have a lower risk of addiction, but they take several weeks to work fully. Thus, alprazolam may be prescribed simultaneously with an SSRI (e.g., sertraline, fluoxetine, escitalopram), so that you can experience the necessary relief while the SSRI takes effect. After two to four weeks, alprazolam is discontinued.

Alprazolam FAQs

Listed below are frequently asked questions about the use of alprazolam.

Can alprazolam be dangerous?

Yes, alprazolam can be dangerous, especially when you take more than prescribed or combine it with alcohol, other drugs, or medications that slow CNS activity. There is also a risk of dependence and addiction, and there are many possible side effects and interactions.

Is alprazolam a controlled substance?

Yes, alprazolam is a Schedule IV controlled substance under the DEA’s Controlled Substances Act, due to its potential for misuse, abuse, dependence, and addiction.

Can you take alprazolam for sleep?

Alprazolam is sometimes used off-label for trouble sleeping (insomnia), but typically only for short-term situations. Do not take alprazolam for sleep if that is not why you were prescribed it initially.

Is alprazolam hard to stop using?

Alprazolam can be difficult to stop using, in part due to its ability to create dependence. Tapering off of alprazolam takes several weeks, and sometimes up to 12 months. Some individuals may not be able to stop using it, especially after taking it continuously for several months to years.
