If you take more Nitrazepam Tablets than you should
If you accidentally take too many tablets, you should contact your doctor or go to your nearest hospital casualty department immediately. Take this leaflet and any unused tablets with you to show the doctor.
The symptoms of mild overdose include feeling confused, drowsiness, reduction in your level of awareness, problems co-ordinating movement, slurred speech, feeling dizzy or light headed, especially when standing up, muscle weakness and breathing problems.
The symptoms of severe overdose include severe breathing difficulties, deep coma, inability to sleep and fits (convulsions). As the level of nitrazepam drops, you may become extremely agitated and have serious difficulty sleeping. You may also experience other withdrawal effects (see section below “If you stop taking Nitrazepam Tablets”).
The doctor will assess your condition and decide how to treat your overdose. You will be monitored and you may be given a medicine called flumazenil to reduce the effects of the overdose. In addition you may be given activated charcoal to reduce the absorption of nitrazepam. When taken alone in overdose, nitrazepam presents few problems in management and should not present a threat to life unless combined with other CNS depressants (including alcohol).
