The capsule-shaped lorazepam tablets are for short-term use within 2-4 weeks only and provide relief from anxiety. The medication is used for children above 5 years of age for operative dentistry and general surgery. However, it is not recommended for children with moderate anxiety or insomnia.

Moreover, this medication should not be immediately stopped. The dosage must be gradually decreased, as there is a possibility of rebound occurrences. For adults, the dosage must be 1 mg to 4 mg daily to treat anxiety and insomnia, and must be taken before going to bed. This medication is not ideal as a primary treatment for depressive disorders and should not be used to treat patients who are depressed.

What is Xanax?

Xanax is a brand name of alprazolam, which also belongs to the benzodiazepine class like lorazepam. It also affects the chemicals in the brain that may be unstable in people suffering from nervousness. It is also used to treat anxiety caused by depression, anxiety disorders, and panic disorders. 

The abnormal excitement in the brain is reduced by the intake of Xanax. The medication slows down the activity of unbalanced brain chemicals, which results in a decrease in anxiety and nervous tension. Xanax works effectively by boosting the effects of gamma-aminobutyric acid (GABA), a natural chemical made in the brain. The drug is 10-20 times potent in comparison to Valium. The commonly used brand names of Xanax include Xanax XR extended-release tablets, Niravam orally disintegrating tablets, and Alprazolam Intensol solution.

Xanax is an oval and biconvex tablet indicated for short-term use. It should not be taken to treat tension that is associated with life's day-to-day stress. The overall duration of the treatment should not exceed more than 8-12 weeks. Taking Xanax can only be extended in certain cases and according to the doctor's advice.

There are only a few patients who require a higher dosage. To avoid any adverse side effects, it is very important to slowly increase its dosage. Patients who have previously received psychotropic medications must be treated with lower dosages of Xanax. The recommended daily reduction of Xanax dosage should not be more than 0.5 mg every three days. 

Similarities between Ativan (lorazepam) and Xanax

Both Ativan (lorazepam) and Xanax (alprazolam) are benzodiazepines, a class of psychoactive drugs. Benzodiazepine drugs are used as sedatives, muscle relaxants, tranquilizers, and sleep aids. They are basically used to relieve nervousness, anxiety, and tension, as well as stop seizures and other psychological symptoms.

The potency of both medications is similar. When they are administered as sedatives, their effect can be witnessed in just 30 minutes, as they are rapid onset medications.

The benzodiazepine class is very broad, which comprises 15 medications that are used to treat anxiety, insomnia, panic attacks, and alcohol dependence. The medications that belong to the benzodiazepine class work in the similar manner but differ in its attributes such as the duration of action, onset of action, and for how long the drug stays in the body.

Differences between Ativan (lorazepam) and Xanax

Lorazepam and Xanax both are particularly used for treating anxiety. The main difference between the two is that lorazepam is used for treating general anxiety disorders while Xanax is used to treat panic attacks and severe anxiety. A milligram of lorazepam is equivalent to 0.5 mg of Xanax. Both these medications are prescribed for short-term use only. The intake of lorazepam is approved for individuals above 12 years old while Xanax can only be taken by individuals who are 18 years old and above.

Ativan, which is a brand name of lorazepam, is a preoperative sedative. Its actions are different in comparison to Xanax. The amount of time when Ativan and Xanax are active is quite different. Overall, Xanax takes lesser time to peak but can only be active for a time. Xanax can take effect within 1-2 hours and its average half-life is about 11-12 hours. On the other hand, the time it takes for Ativan to take effect is 1-6 hours and its average half-life is 14-15 hours.

The other difference between Ativan and Xanax is their addictive qualities. Long-lasting use of any benzodiazepine can lead to addiction and on discontinuing the intake of the medicine, it causes withdrawal symptoms. The abuse potential of Xanax is higher than other benzodiazepines, including Ativan.


Lorazepam medications are available in the form of immediate-release tablets as well as injectable solutions. The injectable solution can be acquired when you are in a hospital and is only administered by a healthcare professional. Xanax is also available in immediate-release tablets that can be swallowed. You can also allow Xanax to dissolve in your mouth. The extended-release Xanax tablets are approved for use to treat panic attacks. Fewer doses of extended-release Xanax tablets must be taken. It is important that the medication is exactly taken according to the doctor's instruction and prescription. The medication should not be shared with any person who has a history of alcohol or substance abuse.
