Get emergency medical help if you have signs of an allergic reaction to Ativan: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Lorazepam can slow or stop your breathing, especially if you have recently used an opioid medication, alcohol, or other drugs that can slow your breathing. A person caring for you should seek emergency medical attention if you have weak or shallow breathing, if you are hard to wake up, or if you stop breathing.
Call your doctor at once if you have:
severe drowsiness;
unusual changes in mood or behavior;
sudden restless feeling or excitement;
thoughts of suicide or hurting yourself;
confusion, aggression, hallucinations;
sleep problems;
vision changes; or
dark urine, or jaundice (yellowing of the skin or eyes).
The sedative effects of lorazepam may last longer in older adults. Accidental falls are common in elderly patients who take benzodiazepines. Use caution to avoid falling or accidental injury.
Common Ativan side effects may include:
dizziness, drowsiness;
weakness; or
feeling unsteady.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
