Precautions

Tell your doctor if you are pregnant or planning to become pregnant. Using this medicine during the later pregnancy may cause problems in your newborn baby (eg, sedation or withdrawal symptoms). Tell your doctor right away if your baby has an abnormal sleep pattern, diarrhea, feeding problems, a high-pitched cry, irritability, low muscle tone, restlessness, shakiness or tremors, sluggishness, trouble breathing, weight loss, vomiting, or fails to gain weight. If you think you have become pregnant while using the medicine, tell your doctor right away.
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 and angioedema, which can be life-threatening and require immediate medical attention. Call your doctor right away if you have itching, hives, hoarseness, nausea or vomiting, trouble breathing, trouble swallowing, or any swelling of your hands, face, mouth or throat while you are using this medicine.
This medicine 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.
This medicine 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 this medicine. Check with your doctor before taking any of the above while you are using this medicine.
This medicine may cause some people, especially older persons, to become drowsy or less alert than they are normally, which may lead to falls. Even though quazepam is taken at bedtime, it may cause some people to feel drowsy or less alert on arising. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.
Do not stop using this medicine without checking first with your doctor. 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, including hallucinations, seizures, stomach or muscle cramps, tremors, or unusual behavior.
This medicine may cause you to do things while you are still asleep that you may not remember the next morning. It is possible you could drive a car, sleepwalk, have sex, make phone calls, or prepare and eat food while you are asleep or not fully awake. Tell your doctor right away if you learn that any of these has happened.
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 this medicine 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.
Symptoms of an overdose include: change in consciousness, changes in patterns and rhythms of speech, hallucinations, loss of consciousness, loss of strength or energy, mood or mental changes, muscle pain or weakness, nightmares, sleepiness or unusual drowsiness, shakiness and unsteady walk, slurred speech, trouble in speaking, trouble sleeping, unsteadiness, trembling, or other problems with muscle control or coordination, unusual drowsiness, dullness, tiredness, weakness or feeling of sluggishness, unusual excitement, nervousness, restlessness, or irritability, or unusual weak feeling. Call your doctor right away if you notice these symptoms.
