Zopiclone · UK information guide

Missed zopiclone dose

What to do if you forget zopiclone and why a late dose can be unsafe.

Medical information: This page provides general educational information and is not a substitute for personal medical advice.
Quick answer: If it is too late to get a full night of sleep, skip the missed zopiclone dose rather than taking it late.

At bedtime

If you remember at your normal bedtime and can allow a full night of sleep, follow the prescribed instructions.

During the night

Do not take a late dose if you need to wake soon; next-day drowsiness and impaired reactions may make this unsafe.

Never double dose

Do not take two tablets to make up for a missed dose.

If too much was taken

Call NHS 111 for urgent advice, or 999 for collapse, abnormal breathing or inability to wake.
