Zaleplon is a sedative-hypnotic medication used for the short-term relief of insomnia by promoting sleep onset.
Zaleplon belongs to the class of medicines called non-benzodiazepine hypnotics. It is used to help people who have trouble falling asleep at the start of the night. The ingredient is found in a few products that are marketed in Hong Kong, such as Hyplon and Zaleplon tablets.
In Hong Kong the two most common products containing this active ingredient are:

The medication is intended for adult patients who need a temporary aid to start sleeping. It is not meant for long-term treatment of chronic insomnia without medical supervision.
Zaleplon encourages the brain’s natural calming pathways, helping to reduce the time it takes to fall asleep. It acts quickly, usually producing sleep within about 15 minutes, and its effects wear off fairly soon after waking.

Store tablets in a dry place at room temperature, away from direct sunlight and out of reach of children. Treatment is usually short-term; prolonged use without a clinician’s review is not advised. Because each brand (Hyplon, Zaleplon) may have slight formulation differences, always follow the specific instructions that come with the medication you receive. For detailed dosing, administration, and monitoring, consult the product label or your health professional.
