how should i use this medication?
the recommended adult dose of nitrazepam when taken for insomnia is 5 mg to 10 mg taken at bedtime.
seniors may be more likely to experience unwanted effects of this medication and should start with 2.5 mg taken at bedtime.
the lowest effective dose should be used. it is important that the dose be individualized to your specific needs to avoid excessive drowsiness during the day time or motor impairment.
this medication is normally used for a short period of time or as an "as required" medication. as it may be habit-forming, the treatment period should be as short as possible and not usually longer than 7 to 10 consecutive days. if you need this medication for more than 2 to 3 weeks, consult your doctor for a re-evaluation of this medication.
when taken for treatment of myoclonic seizures, the dose is based primarily on body weight. the dose for children (up to 30 kg of body weight) ranges from 0.3 mg per kilogram of body weight to 1 mg per kilogram of body weight daily in 3 divided doses. your doctor will calculate an appropriate dose.
many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. if your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
nitrazepam may be habit-forming when taken for long periods of time. it may not be appropriate for people who have a history of alcohol or substance abuse.
if you have been taking this medication regularly, even for a short period of time, do not stop taking the medication without speaking with your doctor. a gradual reduction in dose is recommended when stopping this medication to avoid withdrawal effects.

are there any other precautions or warnings for this medication?
before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. these factors may affect how you should use this medication.
alcohol and other medications that cause drowsiness: people taking this medication 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 and possibly fatal.
asthma and other respiratory conditions: nitrazepam may cause increased breathing difficulty for people having an acute asthma attack, or those with 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 this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
behavioural and mood changes: this medication 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.
complex sleep-related behaviours: there have been reports of complex sleep-related behaviours that have occurred while using nitrazepam and other similar medications to treat difficulty sleeping. people taking 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 this medication, 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 nitrazepam. people who have a history of dependence on alcohol or other medications may be more at risk of developing dependence on 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.
a temporary condition called rebound insomnia, where the symptoms that led to treatment with nitrazepam come back worse than before, may occur on withdrawal of the medication. it may be accompanied by other reactions including mood changes or anxiety.
depression: this medication can make some symptoms of depression worse. if you have depression or a history of depression, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. if you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, or 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 this medication, seek medical help immediately.
drowsiness/reduced alertness: 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 this medication affects you. drinking alcohol can increase the drowsiness effects and should be avoided.
falls and injuries: nitrazepam can cause drowsiness or dizziness that can affect your balance and increase your risk of falling. this can result in fractures or other injuries. your risk of falls is increased if you drink alcohol or take other sedatives while taking this medication, you are elderly or have a condition that causes weakness or frailty.
kidney function: if you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
liver function: people with reduced liver function or liver disease may experience a stronger effect from the medication than would normally occur. if you have reduced liver function or liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
pregnancy: nitrazepam, like other benzodiazepines, can cause harm to an unborn baby if the mother takes it while pregnant. this medication should not be used during pregnancy unless the benefits outweigh the risks. if you become pregnant while taking this medication, contact your doctor immediately.
breast-feeding: this medication passes into breast milk. if you are breast-feeding and are taking nitrazepam, it may affect your baby. talk to your doctor about whether you should continue breast-feeding.
children: the safety and effectiveness of nitrazepam for sleep difficulties have not been established for children and adolescents less than 18 years of age.
seniors: seniors are more likely to experience sedation and decreased coordination when taking nitrazepam. the lowest effective dose of this medication should be used for the shortest possible length of time.
