What it is used for
- Short-term severe anxiety
- Short-term severe insomnia linked to anxiety
- Sedation before procedures
- Certain seizure emergencies (clinical use)
How it works
Lorazepam strengthens the action of GABA, a calming chemical messenger in the brain, reducing excessive nerve activity. This produces a fast calming and sedative effect.
How it is taken
Usually available as tablets and as injections used in clinical settings. It is intended for short-term use because of the risk of dependence. Take it exactly as your doctor or pharmacist directs and follow the label; do not increase the amount, prolong use, or stop suddenly after regular use.
No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.
