Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Oxazepam 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;
a light-headed feeling, like you might pass out;
unusual changes in mood or behavior;
confusion, anger, paranoia, problems with memory or concentration;
tremors, slurred speech, problems with balance or muscle movement;
a seizure;
trouble breathing;
fever, chills, sore throat; or
upper stomach pain, dark urine, jaundice (yellowing of the skin or eyes).
The sedative effects of oxazepam 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 side effects may include:
drowsiness;
dizziness, spinning sensation; or
headache.
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.
