Lorazepam (Ativan) is a benzodiazepine used for short-term treatment of anxiety. The oral tablets and solution are taken by mouth, typically 1 to 3 times daily, depending on the formulation. Lorazepam is also available as an injectable medication that's given by healthcare professionals in a hospital setting to control seizures. Sleepiness and dizziness are the most common side effects of lorazepam (Ativan).

Lorazepam (Ativan) is a fast-acting benzodiazepine. It slows down activity in your brain, to help control anxiety) and stop seizures.
Lorazepam (Ativan) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Taking with opioid pain medications or alcohol | Taking for a longer time and at higher doses than prescribed
Taking lorazepam (Ativan) with opioid pain medications or alcohol can cause severe drowsiness, tiredness, and difficulty breathing, which can be life-threatening.
Some people with long-term pain might already be taking opioid medications. If this applies to you, let your care team know. The combination of lorazepam (Ativan) with opioid medication should be avoided because this raises the chance of overdose. Ask your care team if safer medication options are available. If you or a loved one notices that you're having trouble breathing or waking up easily, get medical help right away.
Risk factors: Taking higher doses of lorazepam (Ativan) over a longer period of time | Stopping lorazepam (Ativan) suddenly
Additionally, taking lorazepam (Ativan) over longer periods of time can raise the risk for physical dependence. If so, suddenly stopping lorazepam (Ativan) can lead to withdrawal symptoms, including hallucinations, a change in behavior, and trouble sleeping. Sometimes, withdrawal symptoms can last weeks to years. Don't stop taking lorazepam (Ativan) without first talking to your HCP. Take lorazepam (Ativan) only as instructed to lower the risk of dependence and overdose.
Risk factors: Severe depression | Psychosis
Taking benzodiazepines, like lorazepam (Ativan), can make depression worse. Watch for new or worsening signs of depression, suicidal thoughts or behavior, or any unusual changes in mood or behavior while taking lorazepam (Ativan). Get medical help right away if you notice any of these changes. Your care team will likely ask you to consider other medications for your anxiety.
Risk factors: Drinking alcohol | Also taking other medications that cause drowsiness | Older adult
Lorazepam (Ativan) can make you feel sleepy and affect your concentration and focus. Drinking alcohol while taking lorazepam (Ativan) and taking additional medications that make you feel drowsy can make this effect worse. Avoid activities that require you to be alert, like driving or operating machinery, until you know how the medication affects you.
Risk factors: Ages 65 years or older | Liver problems | Medical conditions that affect breathing
If you're over the age of 65, you might be more likely to experience side effects from lorazepam (Ativan). Too high of a dose can cause you to have trouble breathing. Your HCP will most likely start you on a very low dose of lorazepam (Ativan). This will help prevent more dangerous side effects. Let your HCP know if you've trouble breathing after taking lorazepam (Ativan).
This medication should also be used with caution in people with certain breathing problems like chronic obstructive pulmonary disease (COPD) or sleep apnea. Lorazepam (Ativan) can affect your breathing, so it can be more dangerous for people with already existing breathing problems.
Risk factors: Ages 65 years or older
In some rare cases, taking medications like lorazepam (Ativan) have led to side effects such as agitation, feeling irritable, violent behavior, confusion, and excitement. If you experience these side effects, let your healthcare team know right away because they'll need to help you stop this medication safely.
Risk factors: Taking lorazepam (Ativan) while pregnant
Lorazepam (Ativan) can cause harm to your baby if you take the medication while you're pregnant. Newborn babies whose parent took lorazepam (Ativan) during pregnancy have experienced serious issues like breathing problems, excessive drowsiness, irritability, and feeding difficulties. If you're planning to have a baby or are currently pregnant, speak with your HCP about the best options for your anxiety or panic disorder.
