Klonopin vs. Xanax

Feelings of anxiety can cause mental symptoms like persistent fear and dread, in addition to physical symptoms such as sweating and a fast heartbeat.

Moreover, regarding their prevalence, anxiety disorders are the most common mental health condition among adults in the United States, affecting nearly 20% of adults annually.

There are various types of anxiety disorders, including:

Not all feelings of anxiety are necessarily linked to a disorder; however, if you feel that anxiety consistently affects your ability to maneuver throughout the day successfully, it may be wise to consult a healthcare provider,

Klonopin contains the active ingredient clonazepam. It is FDA-approved to:

Some healthcare providers prescribe medications off-label. This means prescribing a drug that is not FDA-approved for a particular use.

Sometimes, healthcare providers prescribe Klonopin off-label for conditions such as:

How Does Klonopin Work?

The exact way Klonopin works has yet to be understood entirely. However, it is thought to work on a receptor that binds a neurotransmitter (chemical messenger) typically in thecentral nervous system (CNS)calledgamma-aminobutyric acid (GABA), enhancing its activity.

Klonopin causes a slowing down of the CNS, which causes relaxation and sleepiness and can also help prevent seizures.

It is available in brand and generic forms as oral and orally disintegrating tablets (tablets that dissolve in a person’s mouth.

Xanax contains the active ingredient alprazolam. It is FDA-approved to:

Sometimes, healthcare providers prescribe Xanax off-label for conditions such as:

Dosing Comparison

With benzodiazepines, the healthcare provider will prescribe the lowest effective dose and monitor the individual closely.

When stopping a benzodiazepine, the dosage will be gradually tapered to lower the risk of withdrawal reactions.

Dosage is individualized, and the healthcare provider will determine the best dosage based on various factors. We will provide some general dosing guidelines here.

Klonopin

General dosing guidelines are as follows. However, some individuals may be prescribed one dose at bedtime rather than two daily doses.

For oral dosage forms (tablets or disintegrating tablets):

Seizures:

Panic disorder:

Xanax

The recommended starting dose for GAD is 0.25 or 0.5 mg thrice daily.

The healthcare provider may gradually increase the dosage to a maximum recommended total daily dose of 4 mg given in divided doses.

Anxiety:

For oral dosage forms (solution, tablets, or orally disintegrating tablets):

For oral dosage form (ER tablets):

The American Geriatrics Society publishes lists of medications that may be potentially dangerous in older adults. The list is called the Beers' Criteria for Potentially Inappropriate Medication (PIM) Use in Older Adults, and it helps healthcare providers make prescribing decisions.

The updated 2023 guidelines strongly recommend avoiding benzodiazepines in older adults (65 and older). This is because of the risks of these medications, such as abuse, misuse, addiction, severe sedation, impairment, falls, fractures, car crashes, breathing problems, coma, and death.

However, certain benzodiazepines may be appropriate in specific individuals if the healthcare provider weighs the risks and benefits and determines that the benefits outweigh the risks.

If you are 65 and older, talk to your healthcare provider about the benefits and risks before taking a benzodiazepine medicine.

In addition to medication (which may also include an antidepressant) for anxiety, you can try other things to help with anxiety symptoms.

Alternative options include:

Vistaril (Hydroxyzine) vs. Xanax (Alprazolam) for Anxiety

Summary

Klonopin (clonazepam) and Xanax (alprazolam) are two FDA-approved medications for treating adult anxiety disorders.

Klonopin can also be used to prevent seizures in adults and children. Both drugs are benzodiazepines and controlled substances. Therefore, these benzodiazepines have the potential for abuse and dependence and, thus, are not always safe for everyone.
