Benzodiazepines: Do They Treat Anxiety?

Are benzodiazepines a quick fix or a long-term problem? They are frequently used as an anxiety treatment but have the potential for benzodiazepine side effects and withdrawal.  Learn more about when it may be reasonable to use a benzodiazepine and what the risks are.

What are Benzodiazepines?

There are several different medications in the benzodiazepine family of medicine. Some common ones are Xanax/alprazolam, Klonopin/clonazepam, Ativan/lorazepam, and Valium/diazepam. These medicines differ in how long they take to have an effect and how long the effect lasts. Xanax is short acting. It works quickly going in and out of your system so it can be helpful for a panic attack. Klonopin, on the other hand, is longer lasting so is more useful for people that have ongoing anxiety.

Here is a chart showing the relative strength of each benzodiazepine:


Benzodiazepines as Treatments for Anxiety

First the good news: Anxiety treatment

They can help! For anxiety, benzodiazepines can be helpful for short-term and as-needed relief of symptoms. Benzodiazepines work quickly and can ease anxiety symptoms temporarily. For people with a specific phobia (like fear of flying) they can be useful as an adjunct to skills learned in cognitive-behavioral therapy (although ideally, you won’t need medication once you learn skills!).

Benzodiazepines can also be helpful while waiting for an antidepressant to kick in. Antidepressants generally start to work 3-5 weeks from when you are at a therapeutic dose. This can feel like a lifetime for someone who is suffering from anxiety. In addition, some antidepressants can have an initial side effect of making people feel jittery. This is not pleasant for anyone but especially if you are already anxious! Benzodiazepines can be helpful for this temporary side effect.

Now the bad news: Benzodiazepine side effects

Yes, you can die from them! Some people wonder why I want to take them off their benzodiazepine when they feel it is helping. Unfortunately, benzodiazepines aren’t good as a long-term cure for anxiety. They can produce dependency and a growing tolerance to the effects of the medicine (where larger doses are needed to get the same effect). Here is great blog post on the history of benzodiazepines and concerns about their long-term effects:

Benzodiazepine withdrawal:

With regular use benzodiazepines need to be tapered. Dangerous withdrawal symptoms can happen if they are stopped abruptly (similar to what happens when people go into alcohol withdrawal). Many other unpleasant withdrawal symptoms including insomnia and rebound anxiety can happen once dependent. In addition to physical dependence, there is always a concern for psychological dependence and addiction. Here is additional information on benzodiazepine withdrawal:


Here is an infographic made by Addiction Blog demonstrating what day-to-day withdrawal from Ativan can be like:

Benzodiazepines for anxiety


Anxiety treatment:

There are many different approaches to treating anxiety and some of the most effective treatments aren’t medicine (cognitive-behavioral therapy is one). Benzodiazepines can be a helpful short-term management of anxiety in the right person but are not generally a great long-term solution. They work well as a band-aid but not as a cure!


If you are on a benzodiazepine and want to taper off make sure you do this with the help of a medical professional. The time it takes to get off of them will depend on how high your dose is. Let your doctor help you taper off in a safe way to minimize your withdrawal and come up with a treatment plan for your underlying anxiety.
