SONATA

Read the Medication Guide provided by your pharmacist before you start taking zaleplon and each time you get a refill. If you have any questions, consult your doctor or pharmacist.

Take this medication by mouth as directed by your doctor. Zaleplon works very quickly, so it is important to take it just before or when you get into bed. Your doctor will work with you to find the smallest dose that works for you.

Zaleplon should not be used for naps. Do not take a dose of this drug unless you have time for a full night’s sleep of at least 7 to 8 hours. If you have to wake up before that, you may have some memory loss and may have trouble safely doing anything that needs alertness, such as driving or operating machinery.

Rarely, after taking this drug, people have gotten out of bed and driven vehicles while not fully awake (“sleep-driving”). People have also sleepwalked, prepared/eaten food, made phone calls, or had sex while not fully awake. Often, these people do not remember these events. This problem can be dangerous (possibly fatal) to you or to others. If you find out that you have done any of these activities after taking this medication, tell your doctor right away. You should not take this medication or similar medications (such as eszopiclone, zolpidem) if you have this reaction to the medication.
