Uses For Sonata
Zaleplon belongs to the group of medicines called central nervous system (CNS) depressants (medicines that make you drowsy or less alert). Zaleplon is used to treat insomnia (trouble sleeping). In general, when sleep medicines are used every night for a long time, they may lose their effectiveness. In most cases, sleep medicines should be used only for short periods of time, such as 1 or 2 days, and generally for no longer than 1 or 2 weeks.
This medicine is available only with your doctor's prescription.
Before Using Sonata
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Sleep medicines may cause a special type of memory loss or "amnesia". When this occurs, a person does not remember what has happened during the several hours between use of the medicine and the time when its effects wear off. This is usually not a problem since most people fall asleep after taking the medicine. In most instances, memory problems can be avoided by taking zaleplon only when you are able to get at least 4 hours of sleep before you need to be active again. Be sure to talk to your doctor if you think you are having memory problems.
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of zaleplon in the pediatric population. Safety and efficacy have not been established .
Appropriate studies performed to date have not demonstrated geriatrics-specific problems that would limit the usefulness of zaleplon in the elderly. However, confusion and falling are more likely to occur in the elderly, who are usually more sensitive than younger adults to the effects of zolpidem. Elderly patients may require a lower dose to help reduce unwanted effects .
