How does lorazepam work?
Lorazepam enhances the effects of gamma-aminobutyric acid (GABA), a neurotransmitter that calms the nervous system. This reduces anxiety, promotes sleep, and relaxes muscles.

Lorazepam is commonly prescribed for:
- Anxiety disorders
- Panic attacks
- Insomnia (short-term treatment)
- Seizures or epilepsy (including status epilepticus in emergencies)
- Sedation before medical procedures
Who can take lorazepam?

Can I take lorazepam if I’m pregnant or breastfeeding?
Lorazepam isn’t usually recommended during pregnancy or while breastfeeding, as it may affect the baby. If you are pregnant or planning to conceive, speak to your doctor about alternative treatments.
What if I miss a dose?
If you forget a dose, take it as soon as you remember. If it’s close to your next dose, skip the missed one—do not take two doses at once.
