Why was serax discontinued?

Serax is a brand name for the benzodiazepine oxazepam. Whether it’s been discontinued depends on the country and the manufacturer. In many places the Serax brand has been phased out or replaced, but oxazepam remains available as a generic under its chemical name (oxazepam) or sold under other brand names.

The reasons are usually business-related (company portfolio changes, marketing decisions, or supply chain issues) rather than a universal safety or regulatory ban. There isn’t a single global recall or safety issue that caused all Serax products to disappear.

If you tell me your country (and ideally the year you’re asking about), I can look up the exact status for that market. If you’re trying to fill a prescription, your pharmacist or prescriber can confirm current availability and alternatives.
