Benzodiazepines: the complete list, ranked by safety record

All 12 benzodiazepines we track, ranked by our independent FDA recall-safety score. Unlike a plain list, every drug here carries its safety record, what it treats, whether a generic exists, and how long it stays in your body.

Benzodiazepines are central-nervous-system depressants that calm overactive nerve signaling. The FDA has approved them for anxiety disorders, seizures, insomnia, and managing alcohol withdrawal.

How they work: They act on benzodiazepine receptors that are part of the GABA-A receptor, a chloride channel. In the presence of the brain's own GABA, they increase how often that channel opens, letting chloride into the neuron, hyperpolarizing it, and producing CNS depression.

What everyone taking one should know

Benzodiazepines are habit-forming: regular use can lead to physical dependence, and stopping abruptly can trigger withdrawal reactions, including seizures. They also carry an FDA boxed warning that combining them with opioids can cause severe respiratory depression, coma, and death.

Ranked by our independent recall-safety score (higher is better), which reflects the FDA recall and enforcement record — not effectiveness. A higher score is not medical advice to switch; which drug is right for you is a prescriber’s decision. 5 are unrated (too little regulatory history to score) and sort last.

The list is built from the FDA’s Established Pharmacologic Class tags, so it reflects the drugs in this class that we track (one row per active ingredient). Safety scores come from the FDA recall and enforcement record. This is general reference information, not medical advice — do not start, stop or switch a medication based on it; talk to your prescriber or pharmacist.
