If your condition does not improve within 7 to 10 days, or if it becomes worse, check with your doctor.

Quazepam may cause serious allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention.

Quazepam may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.
Quazepam will add to the effects of alcohol and other central nervous system (CNS) depressants. CNS depressants are medicines that slow down the nervous system, which may cause drowsiness or make you less alert. Some examples of CNS depressants are antihistamines or medicine for hay fever, allergies, or colds, sedatives, tranquilizers, or sleeping medicine, prescription pain medicine or narcotics, barbiturates or seizures medicine, muscle relaxants, or anesthetics (numbing medicines), including some dental anesthetics. This effect may last for a few days after you stop taking quazepam. Check with your doctor before taking any of the above while you are using quazepam.
Quazepam may cause some people, especially older persons, to become drowsy or less alert than they are normally. Even though quazepam is taken at bedtime, it may cause some people to feel drowsy or less alert on arising. Make sure you know how you react to quazepam before you drive, use machines, or do anything else that could be dangerous if you are dizzy, or are not alert or able to see well.
Do not stop taking it without checking with your doctor first. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help prevent a worsening of your condition and reduce the possibility of withdrawal symptoms, such as convulsions (seizures), hallucinations, stomach or muscle cramps, tremors, or unusual behavior.
Quazepam may cause sleep-related behaviors such as driving a car (sleep-driving), walking (sleep-walking), having sex, talking, or preparing and eating food while asleep or not fully awake. If these reactions occur, tell your doctor right away.
If you develop any unusual and strange thoughts or behavior while you are taking quazepam, be sure to discuss it with your doctor. Some changes that have occurred in people taking quazepam are like those seen in people who drink alcohol and then act in a manner that is not normal. Other changes may be more unusual and extreme, such as confusion, worsening of depression, hallucinations (seeing, hearing, or feeling things that are not there), suicidal thoughts, and unusual excitement, nervousness, or irritability.
