Lorazepam (Ativan)

Description

What is Lorazepam?

Lorazepam (commonly known by the brand name Ativan) is a prescription-only benzodiazepine medication used to treat anxiety-related conditions and certain neurological disorders. It works by calming the brain and central nervous system, helping to reduce symptoms such as anxiety, agitation, and insomnia.

Lorazepam is a short-to-intermediate acting benzodiazepine, meaning it works relatively quickly and is often used for short-term symptom relief.

What is Lorazepam Used For?

Lorazepam is commonly prescribed for:

• Anxiety disorders
• Short-term relief of severe anxiety symptoms
• Panic attacks
• Insomnia related to anxiety or stress
• Pre-operative sedation (to relax patients before procedures)

In some cases, it may also be used under specialist supervision for seizure control or alcohol withdrawal.

How Does Lorazepam Work?

Lorazepam enhances the effects of GABA (gamma-aminobutyric acid), a naturally occurring chemical in the brain that promotes calmness and relaxation.

This results in:

• Reduced anxiety and nervousness
• Sedative and calming effects
• Muscle relaxation
• Anticonvulsant activity (helps prevent seizures)

Due to its effectiveness, Lorazepam is typically prescribed for short-term use to minimise risks.

How to Take Lorazepam

Always follow your prescriber’s instructions when taking Lorazepam.

General guidance:

• Take the tablet with water
• Can be taken with or without food
• Usually taken 1–3 times daily, depending on the condition
• Take at the same time each day for consistency

Important:

• Do not exceed the prescribed dose
• Do not suddenly stop taking the medication
• Avoid alcohol while using Lorazepam

Dosage Information

Dosage will vary depending on your medical condition and response to treatment.

• For anxiety: Typically started at a low dose and adjusted gradually
• For insomnia: Usually taken at bedtime
• Elderly patients: Lower doses are recommended due to increased sensitivity

Your healthcare provider will determine the most appropriate dose for you.
