Overview
What is Lorazepam?
Lorazepam is a benzodiazepine medicine used mainly in hospitals and emergency settings for managing severe acute agitation, seizures, and severe anxiety.
Its key clinical advantage over diazepam when given by injection is that its absorption into the muscle is more reliable and predictable. Unlike diazepam, it is broken down without going through the liver’s main processing pathway, making it safer in people with liver disease.
Like all benzodiazepines, lorazepam is intended for short-term use only.
How it works
What does it do in the brain?
Lorazepam works by enhancing the activity of GABA at GABA-A receptors, producing widespread nervous system calming. Its lack of active breakdown products means its effect is more predictable and it does not accumulate in the body over time.

Side effects
What might you feel while taking it?
These are the most commonly reported effects. Not everyone experiences them, and many settle within the first few weeks.
- Sedation and drowsiness
- Dizziness and unsteadiness
- Memory impairment around the time the medicine is working
- Confusion, particularly in elderly patients
- Dependence with regular use beyond a few weeks
Go to a doctor or emergency room straight away if you notice any of the following.
- Breathing difficulty. The risk is highest with injected forms and when combined with other sedating medicines. Resuscitation equipment must be immediately available whenever the injection is used.
- Dependence and withdrawal symptoms with prolonged use
Who should not take it
Important warnings before starting
Tell your doctor about all your medical conditions, allergies, and other medicines before starting Lorazepam.
- Significant breathing problems
- Myasthenia gravis

Special care needed
Situations that need extra attention

- Do not drive or operate machinery while taking it
- Elderly patients are particularly sensitive, lower doses and closer monitoring are needed
- Tell your doctor about any history of substance use problems
Pregnancy

Other medicines
Medicines and substances that can interact with it
Always tell your doctor and pharmacist about every medicine, supplement, and herbal remedy you take, including those bought without a prescription.

- Other sedating medicines: All sedating medicines amplify each other.
Tests and follow-up
What your doctor will monitor
- Breathing and level of consciousness with injectable use
- Duration of treatment, oral lorazepam should be reviewed by two to four weeks
- Signs of tolerance and dependence with ongoing use
Stopping this medicine
What happens if you stop taking it?
Do not stop lorazepam suddenly after regular use. Gradual reduction under medical supervision is needed to prevent withdrawal effects including rebound anxiety and, in severe cases, seizures.
In Kenya
What you should know about this medicine in Kenya
Lorazepam by injection is a valuable tool in Kenyan emergency psychiatric and general emergency settings, particularly because of its reliable muscular absorption.
In combination with haloperidol, lorazepam IM is a standard approach for managing severe acute agitation in Kenyan emergency psychiatric facilities.
As with diazepam, long-term prescribing of oral lorazepam for chronic anxiety is to be avoided.
