Formulations and product identification
The active ingredient alone does not describe a finished product. These distinctions matter when reading a label or comparing prescriptions.
| Product or formulation | Important distinction |
|---|---|
| Oral tablets or concentrate | Product concentration and measuring instructions matter. |
| Injectable lorazepam | Used with clinical monitoring for specific indications. |

Monitoring and treatment follow-up
Treatment review considers anxiety relief, alertness, falls, breathing risk and the other medicines involved. Concentrated liquid requires a suitable measuring device rather than an estimated household volume.

Dependence and stopping treatment
Regular exposure can lead to physical dependence. Stopping suddenly can produce severe withdrawal, including seizures. A withdrawal plan is individualized and is not determined solely by whether the prescribed dose seems small.

How it differs from related medicines
A hospital lorazepam injection is not a model for routine oral dosing. Ativan is a brand name for lorazepam, while other benzodiazepine brands may contain entirely different active ingredients.
