Patient Information Leaflet: Zopiclone
Introduction Zopiclone is a prescription medication used primarily for the short-term treatment of insomnia. As a hypnotic, it helps individuals fall asleep faster and stay asleep longer. It is generally prescribed for a maximum of four weeks to prevent dependency and tolerance.
Indications and Dosage Zopiclone is recommended for short-term use in treating insomnia, with the dosage varying based on the patient’s age and health condition:
- Adults: 7.5 mg taken orally at bedtime for up to 4 weeks.
- Elderly Patients: Initially, 3.75 mg at bedtime, which may be increased to 7.5 mg if necessary.
- Patients with Chronic Pulmonary Insufficiency: A starting dose of 3.75 mg, with potential adjustment to 7.5 mg as needed.
Contraindications Zopiclone should not be used in individuals with the following conditions:
- Severe respiratory failure
- Myasthenia gravis

Cautions and Special Considerations Zopiclone should be used cautiously in patients with:
- A history of depression
- Alcohol or drug dependence
- Chronic pulmonary insufficiency (increased risk of respiratory depression)

Special Considerations for Elderly Patients Elderly individuals are at a higher risk of excessive daytime drowsiness, falls, and coordination issues (ataxia). Regular medication reviews are necessary to ensure safety and efficacy.

Use in Patients with Liver and Kidney Impairment
- Mild to Moderate Hepatic Impairment: A reduced dose of 3.75 mg is recommended.

Patient and Carer Advice
- Driving and Skilled Tasks: Zopiclone may cause drowsiness that persists into the next day, affecting activities such as driving. Alcohol can amplify these effects.

Availability and Prescription Guidelines Zopiclone is available in tablet form (3.75 mg and 7.5 mg). Special-order manufacturers may provide oral suspension or solution for those with swallowing difficulties.
Since Zopiclone is a controlled medication, its prescription is subject to national regulations, which may limit long-term use due to the risk of dependence and withdrawal symptoms.
