Ativan, also known by its generic name lorazepam, is a frequently prescribed medication used to treat anxiety disorders, acute seizures, and as a sedative before medical procedures. While the name might ring a bell, the understanding of this medication often varies among individuals. In this comprehensive guide, we’ll delve into the specifics of Ativan (Lorazepam) 3mg tablets, exploring its various uses, precautions, and side effects. Whether you’re a healthcare professional, a patient seeking information, or someone simply curious about psychiatric medication, this article will provide the insights you need.

Understanding Ativan

Ativan belongs to the benzodiazepine class of drugs, which act on the central nervous system to produce a calming effect by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA). With a rapid onset of action, Ativan is commonly taken orally in the form of tablets, but it can also be administered intravenously for faster effect. The 3mg dose is significant and is usually administered in more acute or severe conditions.

When is Ativan 3mg Prescribed?

The 3mg dose of Ativan is prescribed for more severe anxiety, significant panic attacks, or as a pre-surgery sedative. It is common to see this dosage used in hospital settings for immediate, short-term relief of severe symptoms. It’s important to note that this is a high dose and should only be taken under strict medical supervision due to the increased risk of tolerance, dependency, and potential for abuse.

How Does Ativan Work in the Body?

Upon ingestion, Ativan 3mg is rapidly absorbed by the gastrointestinal tract and reaches peak levels in the blood within two hours. However, under the tongue, or sublingually, the medication gets absorbed more quickly, making it an efficient way to reduce severe anxiety episodes.

The drug binds to specific receptors on the GABA-A complex, which opens chloride channels leading to an influx of chloride ions. This influx causes hyperpolarization of the neuron, which inhibits the activity of the neuron, producing a calming effect on the CNS.

Medical Uses of Ativan 3mg

Here are the primary medical circumstances under which Ativan 3mg is administered:

Acute Anxiety Episodes

Severe, acute anxiety episodes or panic attacks that significantly interfere with daily life can be managed with a dosage of 3mg Ativan tablets, to provide immediate relief and calm to the patient’s central nervous system.

Pre-Surgery Sedation

As a preoperative medication, Ativan 3mg can help reduce anxiety and cause anterograde amnesia, meaning you won’t remember the details of the surgery which can be beneficial to mental health post- surgery.

Status Epilepticus

In cases of status epilepticus, a condition where an individual has continuous seizures, lorazepam can be given as a first-line treatment. It works by calming the excessive electrical and chemical activity in the brain.

Precautions and Considerations

Using Ativan, especially in higher doses like 3mg tablets, requires careful consideration due to the risks of dependency and other potential side effects.

Dependency and Tolerance

Benzodiazepines are known for their potential to lead to physical or psychological dependency. Regular use, especially at high doses, can lead to needing higher doses over time to achieve the same effect (tolerance).

Overdose Potential

An overdose of Ativan can be fatal, especially when taken with other medications or substances that depress the central nervous system.


Discontinuing Ativan after prolonged use can lead to withdrawal symptoms such as rebound anxiety, muscular pain, and in severe cases, seizures. It is important to gradually reduce the dosage under medical supervision.

Side Effects of Ativan 3mg

The 3mg dosage of Ativan, like any medication, is associated with side effects that range from common and less severe to potentially serious.

Common Side Effects

Common side effects might include drowsiness, dizziness, weakness, and unsteadiness. These effects are dose-dependent, which means they are more likely to occur and be more severe at a higher dose.

Less Common but Serious Side Effects

Serious side effects can include slowed breathing, severe allergic reactions, or paradoxical reactions such as increased anxiety, agitation, or hallucinations. If any of these occur, medical attention should be sought immediately.

Long-Term Effects

With prolonged use, especially at higher doses, Ativan can cause memory impairment, both anterograde (difficulty in forming new memories) and retrograde (difficulty in recalling past memories).

Ativan 3mg and Addiction

The use of Ativan 3mg, or any high dosage of lorazepam, must be approached with caution due to the risk of addiction. While benzodiazepines are effective when used appropriately, they are also widely abused drugs, often taken recreationally for their sedative effects.

Identifying Signs of Addiction

Signs of Ativan addiction include a strong desire to continue using the medication, unsuccessful attempts to stop using, spending a lot of time and/or money getting and using the drug, and giving up important social, occupational, or recreational activities because of use.

Getting Help

If addiction is suspected, it’s important to seek help from healthcare professionals. Treatment often involves a combination of therapy and gradual reduction of the drug dose under strict medical supervision to minimize withdrawal symptoms.


Ativan 3mg, as with any medication, is a powerful tool that should be used judiciously and under the care of a healthcare provider. It can provide significant relief for those suffering from severe anxiety, acute seizures, and as a pre-surgery sedative when used appropriately. However, due to the potential for dependency, tolerance, and other side effects, it must be monitored closely and used with caution. Understanding the uses and considerations of Ativan 3mg can empower patients and healthcare professionals to make informed decisions that lead to safe and effective treatment.
