Alcohol and other medications that cause drowsiness: People taking Nitrazadon (Nitrazepam) should not combine it with alcohol and avoid combining it with other medications, such as narcotic pain relievers, or other sedatives that cause drowsiness. Doing so can cause additional drowsiness and reduced breathing as well as other side effects, which can be dangerous.
Asthma and other respiratory conditions: Nitrazadon (Nitrazepam) may cause increased breathing difficulty for people having an acute asthma attack, or those with COPD (Chronic Obstructive Pulmonary Disease) (chronic Bronchitis, emphysema) or other conditions that affect breathing. If you have asthma or any other breathing disorder, discuss with your doctor how Nitrazadon (Nitrazepam) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Nitrazadon (Nitrazepam), and whether any special monitoring is needed.
Behavioural and mood changes: Nitrazadon (Nitrazepam) may cause mood and psychiatric changes, including aggressiveness, confusion, anxiety, restlessness, and memory lapses. Tell your doctor as soon as possible if you notice any unusual changes in your behaviour.

People taking Nitrazadon (Nitrazepam) have been reported to talk, walk, cook, eat, and drive while they were not fully awake, and did not remember doing these things afterwards. If you experience similar events, or notice them in a family member who is taking Nitrazadon (Nitrazepam), contact your doctor as soon as possible.
Dependence and withdrawal: Physical dependence (a need to take regular doses to prevent physical symptoms) has been associated with benzodiazepines such as Nitrazadon (Nitrazepam). Severe withdrawal symptoms may be experienced if the dose is significantly reduced or suddenly discontinued. These symptoms include seizures, irritability, nervousness, sleep problems, agitation, tremors, Diarrhea, abdominal cramps, vomiting, memory impairment, headache, muscle pain, extreme anxiety, tension, restlessness, and confusion. Reducing the dose gradually under medical supervision can help prevent or decrease these withdrawal symptoms.

Depression: Nitrazadon (Nitrazepam) can make some symptoms of depression worse. If you have depression or a history of depression, discuss with your doctor how Nitrazadon (Nitrazepam) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Nitrazadon (Nitrazepam), and whether any special monitoring is needed. If you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, decreased interest in activities, contact your doctor as soon as possible. If you experience feelings of wanting to harm yourself, or notice this in a family member who is taking Nitrazadon (Nitrazepam), seek medical help immediately.
Drowsiness/reduced alertness: Nitrazadon (Nitrazepam) causes drowsiness and sedation. Avoid activities requiring mental alertness, judgment, and physical coordination such as driving or operating machinery until you have determined how Nitrazadon (Nitrazepam) affects you. Drinking alcohol can increase the drowsiness effects and should be avoided.
Kidney function: If you have reduced kidney function or Kidney Disease, discuss with your doctor how Nitrazadon (Nitrazepam) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Nitrazadon (Nitrazepam), and whether any special monitoring is needed.

Pregnancy: Nitrazadon (Nitrazepam), like other benzodiazepines, can cause harm to an unborn baby if the mother takes it while pregnant. Nitrazadon (Nitrazepam) should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Nitrazadon (Nitrazepam), contact your doctor immediately.
Breast-feeding: Nitrazadon (Nitrazepam) passes into breast milk. If you are a breast-feeding mother and are taking Nitrazadon (Nitrazepam), it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of Nitrazadon (Nitrazepam) for sleep difficulties have not been established for children and adolescents less than 18 years of age.
