Which companies manufacture lorazepam (brand and generic)?
Lorazepam is manufactured by multiple pharmaceutical companies, including both brand-name and generic manufacturers. The specific manufacturer depends on the product strength and dosage form (tablets, oral concentrate, injection) and on which labeled product a pharmacy dispenses.
How to find the exact manufacturer on your lorazepam bottle
To identify the manufacturer for the specific lorazepam you have, check the prescription label and the box insert for:
- The listed “manufacturer” or “labeled by” company
- The National Drug Code (NDC) number
- Whether it is a brand product or a generic from a specific company
If you mean the best-known brand: Ativan
Lorazepam is best known under the brand name Ativan. The manufacturer listed on your package is the one that matters for your specific product.
What to do if you need a particular manufacturer
If you are trying to avoid a specific manufacturer (for supply, cost, or personal preference), ask the pharmacy to use a specific NDC or request a particular generic manufacturer when available.
