Free-text change information supplied by the pharmaceutical company

Section 4.2 - the information has been re-formatted, however, no existing information has been removed, nor new information added

Section 4.3 - the following contra-indication has been added;

A hypersensitivty to any of the inactive ingrediants

Section 4.4 - this section has been re-formatted, however, the following information has also been added;

Respiratory Insufficiency

As hypnotics have the capacity to depress respiratory drive, precautions should be observed if zolpidem is prescribed to patients with compromised respiratory function.

Paediatric Patients:

Safety and effectiveness of zolpidem have not been established in patients below the age of 18 years. In an 8-week study in paediatric patients (aged 6-17 years) with insomnia associated with attention-deficit/hyperactivity disorder (ADHD), psychiatric and nervous system disorders comprised the most frequent treatment emergent adverse events observed with zolpidem versus placebo and included dizziness (23.5% vs. 1.5%), headache (12.5% vs. 9.2%), and hallucinations (7.4% vs. 0%). (See Section 4.2 Posology and method of administration). 

Pre-existing depression may be unmasked during use of zolpidem.  Since insomnia may be a symptom of depression, the patient should be re-evaluated if insomnia persists.

Somnambulism and associated behaviours:

Sleep walking and other associated behaviours such as “sleep driving”, preparing and eating food, making phone calls or having sex, with amnesia for the event, have been reported in patients who had taken zolpidem and were not fully awake. The use of alcohol and other CNS-depressants with zolpidem appears to increase the risk of such behaviours, as does the use of zolpidem at doses exceeding the maximum recommended dose. Discontinuation of zolpidem should be strongly considered for patients who report such behaviours (See Section 4.5 Interactions with other medicinal products and other forms of interaction; and Section 4.8 Undesirable effects).

Section 4.5 - this section has been re-formatted to include the CIOMS frequency rating, however, the following information has also been added;

Immune system disorders
Not known: angioneurotic oedema

Psychiatric disorders
Not known: dependence (withdrawal symptoms, or rebound effects may occur after treatment discontinuation), libido disorder
Most of these psychiatric undesirable effects are related to paradoxical reactions

Nervous system disorders:
Common: exacerbated insomnia, amnestic effects may be associated with inappropriate behavrious
Not known: depressed level of consciousness

Gastro-intestinal disorders
Common: diarrhoea

Hepatobiliary disorders
Not known: liever enzymes elevated

Skin and subcutaneous tissues disorders
Not known: rash, pruritus, urticaria

General disorders and administration site conditions
Not known: drug tolerance, fall (predominantly in elderly patients and when zolpidem was not taken in accordance with prescribing recommendation)


Section 4.9 - this section has been re-formatted, however, the following information has also been edited;

Removed: Individuals have fully recovered from zolpidem tartrate overdoses up to 400mg

Added: The value of dialysis in the treatment of an overdose has not been determined.  Dialysis in patients with renal failure receiving therapeutic doses of zolpidem have demonstrated no reduction in levels of zolpidem
