If it is too late to get a full night of sleep, skip the missed dose rather than taking it late.

What to do if a bedtime nitrazepam dose is forgotten.

Medical information: Do not change or stop prescribed nitrazepam without speaking to your prescriber.

Key safety considerations

Nitrazepam can cause drowsiness, impaired coordination, memory problems and dependence. Avoid alcohol and unapproved sedatives, and do not drive if affected.

When to seek help

Call 999 for severe breathing difficulty, collapse, blue lips or a person who cannot be woken. Contact a prescriber or pharmacist for non-emergency concerns about dose, side effects or stopping.
