Nitrazepam is a sedative drug which is used in the short-term to help people sleep.
Nitrazepam belongs to a group of drugs called benzodiazepines. Nitrazepam is used for the short-term treatment of difficulty in sleeping, which is severe, disabling or causing extreme distress.
The tablets should be swallowed preferably with a glass of water just before going to bed. To reduce the risk of loss of memory (amnesia), you should make sure that you are able to have an uninterrupted sleep of at least 7 hours after taking this medicine. The usual dose for dults is usually one 5 mg tablet before going to bed. Elderly or debilitated patients (including those with lung problems, kidney, or liver problems) should not exceed half of the recommended adult dose. You should not take these tablets for any longer than recommended by your doctor, as dependence may occur. It is generally recommended that nitrazepam should not be taken for longer than 4 weeks, including any tapering off period where the dose is gradually reduced.
Do not stop taking your tablets suddenly, or without your doctor telling you, as you may suffer from withdrawal effects. Do not drink alcohol whilst taking these tablets, as it may increase the sedative effect of the drug. Caffeine may reduce the effectiveness of these tablets. Nitrazepam may cause drowsiness, forgetfulness, dizziness, blurred vision, reduced concentration or co-ordination. These effects may be increased if you have not had enough sleep, or if you have taken other medicines or drunk alcohol whilst taking Nitrazepam (see section Taking other medicines). If affected, do not drive or operate machinery. The medicine can affect your ability to drive as it may make you sleepy or dizzy.

If you fall asleep without having taken a dose and wake up some hours later, do not take the missed dose. If necessary, return to your normal dose schedule the following night. Do not take a double dose to make up for a forgotten dose.
If you (or someone else) swallow a lot of the tablets all together, or if you think a child has swallowed any of the tablets, contact your nearest hospital casualty department or your doctor immediately. An overdose is likely to cause drowsiness, confusion, breathing difficulties, low blood pressure, difficulty in controlling movements and slurred speech. In children behavioural changes are likely to occur.
