Why Benzodiazepines Are Not Recommended for PTSD

If you take a benzodiazepine, read this first

This article is not a reason to worry or to change anything on your own. Many people were prescribed a benzodiazepine for a real need, and taking it as directed is not a failing. The National Center for PTSD says that benzodiazepines are sometimes prescribed for short-term use to treat extreme anxiety, panic or sleep problems.

The most important safety point comes first. The alprazolam (Xanax) label warns that stopping abruptly or reducing the dose quickly after continued use may cause acute withdrawal reactions, which can be life-threatening. It calls for a gradual taper. The National Center for PTSD says that if you take one for PTSD, work with your provider on a plan.

What the guideline says, in its own words

The statement reads: "We recommend against benzodiazepines for the treatment of PTSD." In the guideline's system, "we recommend against" means Strong against. It uses the same strength for cannabis or cannabis derivatives.

The panel's confidence in the evidence was very low, because very little research has tested these medicines for PTSD. Its conclusion rests on the balance: "The potential harms of these medications (e.g., cognitive changes, misuse) outweighed the benefits because no evidence of long-term benefit was found." So a strong recommendation does not mean there are many trials. It means the panel saw clear harms and no proven long-term gain.

The reasons, in plain language

• Short-term relief does not last. The guideline's patient focus group noted interest in these medicines because they are effective for short-term anxiety relief, and the guideline says they are ineffective in the long term and can be harmful.
• Other treatments may be affected. The guideline links them with decreased effectiveness of recommended PTSD treatments. The National Center for PTSD says they can make talk therapy less effective.
• Thinking and memory. The guideline names cognitive changes, especially in older adults. The National Center for PTSD also notes increased falls and mental clouding in older people.
• Misuse and dependence. The guideline names misuse, and the label covers abuse, misuse and addiction as well as physical dependence.

The boxed warning on these medicines

Benzodiazepines are FDA-approved for other conditions. The Xanax label, for example, lists acute treatment of generalized anxiety disorder and treatment of panic disorder in adults. PTSD is not on it, so use for PTSD would be off-label.

That label has a boxed warning with three parts. Taking benzodiazepines with opioids may cause profound sedation, slowed breathing, coma and death. Use exposes people to risks of abuse, misuse and addiction, which can lead to overdose or death. And continued use may lead to physical dependence, with the withdrawal risk described above. If you are pregnant, planning to become pregnant or breastfeeding, tell your prescriber.

The label also lists alprazolam as a Schedule IV controlled substance. As of November 2026, a temporary federal rule (Federal Register, Fourth Temporary Extension) allows DEA-registered practitioners to prescribe Schedule II to V medicines by audio-video telemedicine without a prior in-person evaluation, under set conditions, through December 31, 2026. Rules may change after that date.

Questions to bring to your prescriber

• What is this medicine treating for me, and how will we know whether it is still helping?
• How does the guideline's position on PTSD apply to my situation and my other conditions?
• If we ever change my dose, how would a gradual plan work, and what should I watch for?
• Do any other medicines I take, including opioids or sleep aids, raise my risk?
• What other treatments could help with what I feel, including therapy?
