Does Ativan (lorazepam) cause respiratory depression?
Yes. Ativan (lorazepam) can cause respiratory depression, especially when doses are high or when it’s combined with other central nervous system (CNS) depressants (such as alcohol, opioids, or other sedatives). Benzodiazepines like lorazepam slow brain activity, which can reduce breathing drive in susceptible situations.
When is the risk highest?
Respiratory depression risk goes up when Ativan is used:
- With opioids (for example, oxycodone, hydrocodone, fentanyl) or other sedatives (sleeping pills, barbiturates, some antihistamines).
- At higher doses, or in patients who are elderly, have chronic lung disease (like COPD), or have sleep apnea.
- In people with other conditions that already impair breathing.
- As part of misuse or overdose (including taking more than prescribed).
What does “respiratory depression” look like in real life?
Patients may show signs of excessive sedation, slow or shallow breathing, unusual drowsiness, trouble staying awake, or bluish lips/fingertips (a late sign). In overdose, breathing can become dangerously slow.
What should you do if breathing becomes slow or labored?
Seek emergency care immediately if someone who took Ativan has slow breathing, is hard to wake, or shows cyanosis (blue/gray lips or skin). Overdoses involving benzodiazepines plus opioids or alcohol can progress quickly.
Can Ativan respiratory depression be reversed?
Medical teams may use supportive care (airway/breathing support). In some benzodiazepine overdoses, clinicians may use flumazenil as an antidote in selected cases, but it is not appropriate for everyone (for example, certain seizure risk situations or mixed overdoses).
Does this happen at normal prescribed doses?
It’s less common at typical prescribed doses used as directed, but it can still occur in high-risk patients or when combined with other depressants. The key risk factor is the combined effect on the CNS and breathing.
What patients commonly ask about: alcohol and opioids together
Mixing Ativan with alcohol or opioids is one of the most important risk scenarios for breathing suppression. If Ativan was prescribed, avoid alcohol and only use opioid pain medicines or other sedatives if the prescriber specifically approves it.
