Quick Answer
What are the side effects of lorazepam (Ativan)? Common side effects include drowsiness, dizziness, poor coordination, blurred vision, headache, nausea, and confusion or forgetfulness.

Lorazepam, commonly known by the brand name Ativan, is a prescription medication that belongs to a class of drugs called benzodiazepines.
Doctors often prescribe it to treat anxiety, sleep problems, and in some cases, seizures. While lorazepam can be effective in managing these conditions, it also comes with risks. Before taking this medication, it’s essential to understand the side effects of lorazepam, how it affects the body, and the dangers of long-term use.
What Is Lorazepam Used For?
Lorazepam works by calming the brain and nervous system. It increases the effects of a natural chemical in the body called GABA (gamma-aminobutyric acid), which helps reduce anxiety, promote relaxation, and improve sleep. Because of these calming effects, doctors commonly prescribe lorazepam for:
- Generalized anxiety disorder (GAD)
- Panic attacks
- Insomnia
- Seizures
- Alcohol withdrawal symptoms
- Pre-surgery sedation
Even though it is effective in the short term, lorazepam is usually recommended only for brief use because it carries real risks, including dependence and serious side effects.
Common Side Effects of Lorazepam
When someone takes lorazepam, certain side effects are common, especially during the first few days or with higher doses. These include:
- Drowsiness and fatigue
- Dizziness or lightheadedness
- Poor coordination or clumsiness
- Blurred vision
- Headaches
- Nausea
- Confusion or forgetfulness
- Feeling unsteady or off-balance
These symptoms often improve as the body adjusts. However, it is crucial to avoid activities that require full alertness, like driving, until you know how lorazepam affects you.
Serious Risks and Lorazepam Side Effects
Beyond the more common side effects, lorazepam can cause more serious health problems. These risks become even greater with long-term use or when combined with substances like alcohol, opioids, or other sedatives.
Some of the more serious Ativan side effects include respiratory depression, which is slowed or difficult breathing that becomes especially dangerous when mixed with other depressants. It can also cause severe sedation, leading to extreme tiredness or the inability to stay awake. People may experience cognitive problems, such as memory issues, confusion, or difficulty concentrating, especially with long-term use.
Depression and mood changes are also possible, with some individuals noticing a worsening of mental health symptoms over time. One of the most serious risks is dependence and addiction, as lorazepam is highly addictive even when taken exactly as prescribed. In addition, stopping lorazepam suddenly can trigger withdrawal symptoms like rebound anxiety, insomnia, sweating, tremors, seizures, and severe agitation.
Because lorazepam works by calming the nervous system, the body can become dependent on its effects. When the medication is removed, the nervous system can rebound into a state of overactivity, which is what leads to withdrawal symptoms.
Lorazepam Withdrawal Symptoms and Dependence
One of the biggest concerns with lorazepam is how quickly physical and psychological dependence can develop. Dependence means the body gets used to having the drug, and stopping suddenly causes lorazepam withdrawal symptoms.
Withdrawal symptoms may include:
- Severe anxiety or panic attacks
- Insomnia
- Irritability and mood swings
- Sweating and shaking
- Nausea and vomiting
- Muscle pain and stiffness
- Heart palpitations
- Seizures (in severe cases)
Because withdrawal can be dangerous, especially after long-term use, it is critical to follow a tapering process. This means slowly reducing the dose under medical supervision to allow the body to adjust safely.
Dangers of Long-Term Lorazepam Use
Long-term lorazepam use is rarely recommended. While it can provide short-term relief for anxiety or insomnia, the risks increase the longer someone uses it.
Long-term use can lead to:
- Cognitive decline: Problems with memory, learning, and attention.
- Emotional blunting: Feeling emotionally numb or detached.
- Physical dependence: Needing higher doses to feel the same effects.
- Increased anxiety: Over time, lorazepam can actually make anxiety worse when not taken.
- Depression: Some users report feeling more depressed after extended use.
- Risk of overdose: Especially if combined with alcohol or opioids.
Benzodiazepines like lorazepam should never be stopped suddenly if used for more than a few weeks. Medical detox may be needed to manage withdrawal safely.
Should You Take Lorazepam? Understanding the Risks
Lorazepam can be a helpful medication in the short term for specific conditions. However, the risks of lorazepam mean it’s not meant for long-term management of anxiety or sleep issues. Safer alternatives like therapy, non-addictive medications, or lifestyle changes can be more effective and sustainable over time.
If you or someone you love has become dependent on lorazepam or is struggling with misuse, you are not alone. Many people start using it under medical supervision and later find themselves trapped in a cycle of dependence.
Frequently Asked Questions
What are the most common side effects of lorazepam (Ativan)?
The most common side effects are drowsiness, dizziness, poor coordination, blurred vision, headache, nausea, and confusion or forgetfulness. They tend to be strongest in the first few days or at higher doses and often ease as your body adjusts. Because Ativan is a brand name for lorazepam, the side effects are the same.
What is the most serious side effect of lorazepam?
The most serious risks are slowed or difficult breathing (respiratory depression), heavy sedation, and dependence. Respiratory depression becomes especially dangerous when lorazepam is combined with alcohol, opioids, or other sedatives. Dependence can develop even when the medication is taken exactly as prescribed.
Is lorazepam the same as Ativan?
Yes. Lorazepam is the generic name and Ativan is a common brand name for the same medication, a benzodiazepine used for anxiety, sleep problems, and seizures. They share the same effects, risks, and side effects.
What are the long-term side effects of lorazepam?
Long-term use can lead to memory and attention problems, emotional blunting, physical dependence, and, over time, worsening anxiety or depression. Because of these risks, lorazepam is usually recommended only for short-term use.
What happens when you stop taking lorazepam?
Stopping suddenly after regular use can cause withdrawal symptoms such as rebound anxiety, insomnia, sweating, tremors, and, in severe cases, seizures. Benzodiazepines should be tapered slowly under medical supervision rather than stopped all at once.
How long do lorazepam side effects last?
The common side effects like drowsiness usually last a few hours per dose and often lessen within the first days of treatment as your body adjusts. Effects tied to dependence or withdrawal can last longer and are best managed with a provider.
