By the pharmaranks editorial teamReviewed against FDA, NHS & MedlinePlus sourcesHow we research

Both are benzodiazepines approved for anxiety, and they carry the same boxed warning. Valium's label also covers uses Ativan's oral label does not, and its contraindication list is longer.

The key difference

One difference that matters is what each label is approved for. Ativan's oral label is for management of anxiety disorders and short-term relief of anxiety symptoms. Valium's covers anxiety too, and additionally lists symptomatic relief in acute alcohol withdrawal, adjunctive use for skeletal muscle spasm and for spasticity from upper motor neuron disorders, and adjunctive use in convulsive disorders. Another labelled difference: Valium is contraindicated in myasthenia gravis, sleep apnea syndrome, severe respiratory insufficiency and severe hepatic insufficiency — conditions Ativan's contraindications section does not name. Both are contraindicated in acute narrow-angle glaucoma.

Both labels carry the same boxed warning. Taken with opioids, benzodiazepines can cause profound sedation, respiratory depression, coma and death. Both expose users to abuse, misuse and addiction. Both can cause physical dependence, and stopping abruptly after continued use can precipitate withdrawal reactions the labels call life-threatening — so the labels direct a gradual taper.

What favours Ativan (lorazepam)

For anxiety there is no patient-facing reason to prefer lorazepam — the labelled indication is the same, and the choice belongs to your prescriber, weighing your history, your other medicines and how long treatment is expected to last. What Ativan's oral label does not do is claim the extra uses Valium's does.

What favours Valium (diazepam)

Diazepam is the one whose label actually covers acute alcohol withdrawal, muscle spasm and spasticity, and adjunctive use in seizure disorders. If a prescriber is treating one of those, that is a labelled reason to reach for Valium. Its longer contraindication list has to be cleared first.

Bottom line

For anxiety, these two are more alike than the internet pretends: same class, same boxed warning, and both labels say effectiveness beyond four months has not been established in systematic studies. The real fork is Valium's broader set of approved uses against its longer contraindication list — a call your prescriber makes, not a preference you pick.

Two things to take away either way. Do not combine either with an opioid painkiller unless your prescriber has explicitly decided the combination is necessary. And do not stop either on your own: after continued use, abrupt discontinuation can trigger withdrawal reactions the labels call life-threatening, and both direct a gradual taper. Coming off one starts with your doctor.

We rate drugs on their FDA recall record and sell neither, which is why we can tell you the honest answer is "ask your prescriber" instead of steering you.

This is not a summary of either drug’s FDA label, and it is not complete. Both labels carry warnings, contraindications and interactions that are not on this page. Read the label for the drug you are actually taking — we link both above — and take the decision to your prescriber.

Possible drug interaction. ATIVAN and VALIUM are different prescription medicines. Combining or switching between them can cause interactions — talk to a pharmacist or prescriber before making changes. This page is not medical advice.

Valium costs pharmacies less to acquire — about $0.87 vs $1.14 for a 30-count supply, per the CMS NADAC survey. That gap is in the pharmacy's cost of goods, not necessarily in what you pay: your price is set afterwards by your insurer and the pharmacy.
