Anxiety disorders are on the rise. According to the World Health Organization, the mental health condition characterized by excess worry and restlessness affects over 359 million people worldwide.
In the US, roughly 6.8 million adults are living with Generalized Anxiety Disorders (GAD), per the Anxiety and Depression Association of America. It’s also common for the condition to go hand in hand with other psychiatric issues, particularly depression.
SSRIs and SNRIs are standard prescriptions for treating GAD and panic disorders. In cases of severe anxiety, healthcare providers may recommend Benzodiazepines like Lorazepam and Xanax as a short-term intervention to manage acute GAD symptoms.
However, if you or any of your loved ones is undergoing treatment for anxiety, you may wonder how these drugs work and whether they’re safe.
In this guide, we’ll explain how Lorazepam and Xanax work in alleviating anxiety, comparing their effects. We’ll discuss both drugs’ potential for abuse, dependence, and withdrawal, as well as the best treatment options for benzodiazepine addiction.

How Do Lorazepam and Xanax Work?
Benzodiazepines, colloquially called “benzos,” are depressant drugs that affect the central nervous system (CNS). They’re under Schedule IV controlled substances and are legally available only with a doctor’s prescription.
Xanax and Lorazepam are benzodiazepines.
Lorazepam is commonly sold under the brand name Ativan, while Xanax is the brand name for the generic ingredient alprazolam. Valium, Restoril, and Klonopin are other well-known benzodiazepine medications.
How These Drugs Treat Anxiety
In simple words, benzodiazepines help with GAD and panic disorders by slowing down your central nervous system, making it less active, and helping in managing various conditions and symptoms.
They work differently from antidepressants, which target specific mood-related chemical imbalances in the brain.
“Benzos” enhance the effects of the neurotransmitter that regulates your brain activity, the gamma-aminobutyric acid (GABA). This is what makes it effective for panic attacks, mania, seizures, and similar illnesses.
Benzodiazepines can be used to achieve a range of effects, such as:
- Amnestic: Coming from the Greek word for “forgetfulness,” benzodiazepines can block the formation of new memories in the brain. This is a temporary state that can occur after taking the medication.
- Sedative: Sedation is among the key effects of benzodiazepines. This calming effect makes people feel more relaxed, which can help in episodes of acute anxiety and panic attacks.
- Hypnotic: Due to the substance’s sedative properties, medical professionals may recommend benzodiazepines to promote sleep in patients struggling with sleep disorders, such as insomnia.
- Anxiolytic: This term practically means “to loosen or dissolve anxiousness” in Greek. It relates to the medication’s ability to relieve restlessness and excessive worry, common symptoms of anxiety disorders.
While they share a similar set of medical effects, benzos are primarily classified by brand, depending on their strength and duration of action. This is where Xanax and Lorazepam mainly differ.
Uses and Effects of Xanax and Lorazepam
Xanax and Lorazepam have an identical mechanism of action. Both are FDA approved as treatment of anxiety, insomnia, social phobia, seizures, and panic disorders, but they’re not recommended for long-term use.
It’s worth noting that Lorazepam isn’t explicitly approved for panic disorders, but physicians can prescribe the drug off-label for this purpose.
Similarities
Both Xanax and Lorazepam are benzodiazepines, so the short-term reactions in patients who take them tend to be similar. Common side effects for both medications may include:
- Drowsiness
- Confusion
- Headache
- Dizziness
- Nausea
- Fatigue
- Poor coordination
Fatigue, slurred speech, mood swings, irritability, and appetite changes are observed more in patients who took Xanax. Allergic reactions and suicidal ideation are rare in both prescription medications.
If you or someone you know experiences shortness of breath, seizures, eye discoloration, skin rash, or difficulty speaking after ingesting benzodiazepine, promptly seek medical help.
Key Differences
One of the key differences between Xanax and Lorazepam is in their onset of action. Xanax is fast-acting and could take effect within 30 minutes. On the other hand, patients may notice the effects of Ativan 1 to 2 hours after intake.
However, if you’re using injectable Ativan for GAD and panic disorders, your symptoms can subside quickly in under 15 minutes, depending on the area of administration (vein or muscle).
Another notable contrast is the time it takes for your body to metabolize the medication. Lorazepam has a longer half-life of about 12 to 18 hours. Its effects are longer-lasting but stay in your system for several days.
Besides the slower onset, Xanax also has a shorter half-life of 11 hours.
The recommended dose of benzodiazepine can vary, too. Medical professionals typically prescribe them sparingly, often starting with the lowest possible dosage, slowly moving up the dose.
For anxiety disorders, Lorazepam is prescribed in 2 to 6 milligram doses per day. Chronic cases may require higher doses of 10 milligrams. Xanax is usually divided into portions of 0.25 to 0.5 milligrams.
Risks and Side Effects of Long-Term Use
There’s a reason benzodiazepine is only ever recommended for temporary use whenever possible. Some adverse effects associated with abusing Xanax and Lorazepam can include the following:
- Visual-spatial problems
- Learning issues
- Lowered IQ
- Dependence
- Inability to concentrate
- Decreased reaction time
The risk of overdose from benzodiazepines increases with extended periods of heavy use. Ingesting more than your body can handle can lead to CNS depression, mental confusion, and lethargy.
Severe cases can also result in extreme sedation, slowed breathing, muscle weakness, or coma, all fatal scenarios that could result in death. If you suspect you or someone near you is overdosing on Xanax or Ativan, call 911 immediately.
Benzodiazepine Drug Interactions
Combining benzos with other drugs is unsafe. Respiratory depression and low blood pressure may worsen. It also puts the person at a higher risk of fatal overdose.
Be honest and tell your healthcare provider about your medical history and the medicines or supplements you take. This includes opioid medications for alcohol withdrawal, antidepressants, painkillers, antihistamines, antiseizures, and anesthetics.
Are Lorazepam and Xanax Medications Addictive?
Yes, most benzodiazepine drugs, including Lorazepam and Xanax, have the potential to become addictive if used outside medical supervision.
It’s not common for patients to develop psychological and physical dependence after prolonged exposure to Lorazepam and Xanax. This is when the body becomes used to functioning with the substance’s presence.
While it doesn’t always lead to addiction, withdrawal symptoms typically follow dependence. Additionally, the person’s tolerance to the substance can increase, compelling them to use the drug more frequently and in higher amounts.
With continued abuse, the person can start losing control of their cravings, experiencing intense urges for the drugs. Impaired control is a key characteristic of addiction.
Signs of Benzodiazepine Misuse
Identifying signs of early substance abuse is crucial for early addiction treatment and intervention. Get help if you or any of your loved ones are exhibiting any of these signs after taking Lorazepam or Xanax:
- Taking more of the drug than the physician required
- Keeps talking and thinking about benzos
- Becomes angry or irritable when craving the drug
- Lying or stealing to get more of the substance
- Goes to great lengths to acquire benzodiazepines
- Inability to stop using despite its impact on their well-being
Chronic abuse of depressants can also present physically and mentally. Someone misusing Lorazepam or Xanax can develop anorexia, an eating disorder that causes excessive weight loss.
Difficulty sleeping, blurred vision, forgetfulness, cognitive impairments, tremors, sexual dysfunction, and recurring headaches are observed, too.
Lorazepam and Xanax Withdrawal Symptoms
Benzodiazepine withdrawal can vary from one person to another. Symptoms can range from mild to severe, life-threatening health complications.
Depending on the duration and frequency of use, as well as the patient’s age, gender, and overall health, they may experience:
- Heart palpitations
- Anxiety
- Depression
- Confusion
- Diarrhea
- Panic attacks
- Decreased appetite
- Muscle pains
- Abnormal sweating
Severe withdrawal symptoms of benzodiazepine withdrawal can include blacking out, paranoia, hallucinations, and delusions. Seizures are rare but can vary widely, from mild, single episodes to life-threatening complications.
Treatment Options For Benzodiazepine Addiction
Treatment centers offer evidence-based treatment plans to help you manage and recover from Lorazepam or Xanax addiction.
- Detox: Clinically supervised detoxification helps you manage withdrawal symptoms safely and in secure facilities. Tapering is usually recommended for benzodiazepines.
- Inpatient and Outpatient Care: Treatment programs are categorized between inpatient rehab in a residential setting and outpatient care, where you can live at home while receiving treatment.
- Behavioral Therapy: Counseling and talk therapy aim to resolve underlying issues that reinforce substance use. Cognitive behavioral therapy (CBT) is a popular intervention that teaches coping skills.
- Aftercare Programs: Continuing care is crucial to preventing relapse. This is offered as part of standard SUD interventions and can include support groups and other initiatives.
Bottom Line: Finding Expert Support
Lorazepam and Xanax are valuable medications for treating various mental health disorders. However, they also come with a substantial risk of dependence and addiction.
For people helplessly spiraling into benzodiazepine misuse, you’re not alone, and recovery is possible.
