What is the most important information I should know about zaleplon (Sonata)?

Some people using this medicine have engaged in activity such as driving, eating, or making phone calls and later having no memory of the activity. If this happens to you, stop taking zaleplon and talk with your doctor about another treatment for your sleep disorder.

Zaleplon can cause side effects that may impair your thinking or reactions. You may still feel sleepy the morning after taking the medication. Until you know how this medication will affect you during waking hours, be careful if you drive, operate machinery, pilot an airplane, or do anything that requires you to be awake and alert.

Do not drink alcohol while you are taking zaleplon. It can increase some of the side effects of zaleplon, including drowsiness.

Zaleplon may be habit-forming and should be used only by the person it was prescribed for. Zaleplon should never be shared with another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it.

You may have withdrawal symptoms if you stop taking zaleplon after taking it over several days in a row. Do not stop taking zaleplon suddenly without first talking to your doctor. You may need to use less and less before you stop the medication completely.
