✅ Indications
Zunestar 3 mg is prescribed for the short-term treatment of insomnia, particularly to help with:

⚙️ Mechanism of Action
Eszopiclone, the active ingredient in Zunestar, is a non-benzodiazepine hypnotic. It works by enhancing the activity of gamma-aminobutyric acid (GABA) at GABA-A receptors in the brain. This action induces sedation, helping both with sleep initiation and maintenance, making it a reliable treatment for insomnia.
💊 Dosage & Administration
- Recommended Dose: 3 mg, taken orally just before bedtime.
- Administration: For best results, take Zunestar on an empty stomach, approximately 30 to 45 minutes before sleep.
- Duration: Intended for short-term use only (2 to 4 weeks). Long-term use is not recommended.
- Caution: Ensure you get 7–8 hours of sleep after taking the medication to avoid residual drowsiness the next day.
⚠️ Warnings & Precautions
- Dependence Risk: Prolonged use can lead to physical and psychological dependence. It should only be used for the prescribed duration.
- CNS Depression: Zunestar may impair coordination, judgment, and alertness. Avoid activities like driving or operating heavy machinery until you understand how it affects you.
- Alcohol Interaction: Avoid alcohol while taking Zunestar, as it can significantly increase sedation and the risk of adverse effects.
