Tell your doctor or other health professional about all other medicines you are taking, including vitamins, herbal supplements and over-the-counter medicines. Notify your prescriber if you use alcohol or illegal drugs frequently as they may affect how your medicine works. Check with your doctor before starting or stopping any of your medicines.
What should I watch for while taking quazepam?
See your doctor or other healthcare professional regularly to assess your response to quazepam and to determine if you still need it. Quazepam may make you drowsy or dizzy and you should not operate machinery, drive or do anything that requires mental alertness until you see how quazepam affects you. Quazepam can have these effects even the day after you take it. Avoid alcoholic drinks because they can increase the dizziness and drowsiness that you experience. Check with your doctor or healthcare professional before taking other medicines that could make you drowsy such as sedatives, tranquilizers, narcotic pain medicine, other sleeping pills, or cold or allergy medicines.

Be sure to talk to your doctor if you think you are having memory problems while on this medication.
