Ativan, also known as lorazepam, is a commonly prescribed medication that belongs to the benzodiazepine class of drugs. It is primarily used to treat anxiety disorders, insomnia, seizures, and alcohol withdrawal symptoms. However, one lesser-known side effect of Ativan is its potential to cause low blood pressure or hypotension in some individuals. In this article, we will explore the relationship between Ativan and low blood pressure, its causes, symptoms, and how to manage this side effect effectively.

Understanding Low Blood Pressure

Low blood pressure, or hypotension, occurs when the pressure exerted by the blood against the walls of the arteries is lower than normal. This can lead to inadequate blood flow to vital organs, resulting in symptoms such as dizziness, fainting, and fatigue. While low blood pressure can be a temporary condition caused by factors like dehydration or medication side effects, it can also be a chronic condition that requires medical attention.

Causes of Low Blood Pressure

Low blood pressure can be caused by various factors, including:

  • Dehydration
  • Heart problems, such as weak heart muscles or heart valve issues
  • Endocrine problems, such as thyroid disorders or adrenal insufficiency
  • Nervous system disorders, such as Parkinson’s disease or multiple system atrophy
  • Medications, including certain antidepressants, diuretics, and benzodiazepines like Ativan

Ativan and Low Blood Pressure

Ativan works by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain, which helps reduce anxiety and induce relaxation. While Ativan is generally safe and well-tolerated, it can cause a drop in blood pressure as a side effect. This occurs because Ativan has a sedative effect on the central nervous system, which can lead to vasodilation and decreased heart rate.

Symptoms of Ativan-induced Low Blood Pressure

Individuals who experience low blood pressure as a side effect of Ativan may exhibit the following symptoms:

  • Dizziness or lightheadedness
  • Fainting or near-fainting episodes
  • Blurred vision
  • Weakness or fatigue
  • Nausea

Managing Ativan-induced Low Blood Pressure

If you are prescribed Ativan and experience low blood pressure as a side effect, it is essential to discuss your symptoms with your healthcare provider. They may adjust your dosage or recommend alternative medications to minimize the risk of hypotension. Here are some tips to manage Ativan-induced low blood pressure:

1. Stay Hydrated

Dehydration can exacerbate low blood pressure, so it is crucial to drink an adequate amount of water throughout the day. Avoid excessive caffeine or alcohol consumption, as they can contribute to dehydration.

2. Change Positions Slowly

Rapid changes in position, such as standing up quickly, can cause a sudden drop in blood pressure. To prevent this, take your time when transitioning from lying down to sitting or standing. This allows your body to adjust gradually and reduces the risk of dizziness or fainting.

3. Avoid Hot Environments

Exposure to hot temperatures can cause blood vessels to dilate, leading to a drop in blood pressure. Try to stay in a cool and well-ventilated environment, especially during hot weather or when taking hot showers.

4. Monitor Blood Pressure Regularly

If you are prone to low blood pressure, it is essential to monitor your blood pressure regularly. This can help you identify any significant changes and allow your healthcare provider to adjust your medication dosage if needed.


While Ativan is an effective medication for managing anxiety and other conditions, it can cause low blood pressure as a side effect. If you experience symptoms of low blood pressure while taking Ativan, it is crucial to consult your healthcare provider for proper evaluation and management. By following the tips mentioned above and working closely with your healthcare team, you can effectively manage Ativan-induced low blood pressure and ensure your overall well-being.
