Before Using

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.

Pediatric

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.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric specific problems that would limit the usefulness of zaleplon in the elderly.

If you think you need to take zaleplon for more than 7 to 10 days, be sure to discuss it with your doctor. Insomnia that lasts longer than this may be a sign of another medical problem.

Zaleplon may cause serious allergic reactions, including anaphylaxis and angioedema, which can be life-threatening and require immediate medical attention. Call your doctor right away if you have a rash, itching, hives, trouble breathing or swallowing, or any swelling of your hands, face, mouth, or throat while you are using this medicine.

This medicine will add to the effects of alcohol and other central nervous system (CNS) depressants (medicines that make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies or colds, sedatives, tranquilizers, or sleeping medicines, prescription pain medicine or narcotics, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the above while you are using this medicine.

This medicine may cause some people, especially older persons, to become drowsy, dizzy, lightheaded, clumsy or unsteady, or less alert than they are normally, which may lead to falls. Even though zaleplon is taken at bedtime, it may cause some people to feel drowsy or less alert on arising. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

If you develop any unusual and strange thoughts or behavior while using zaleplon, be sure to discuss it with your doctor. Some changes that have occurred in people using this medicine are like those seen in people who drink alcohol and then act in a manner that is not normal. Other changes may be more unusual and extreme, such as confusion, hallucinations (seeing, hearing, smelling, or feeling things that are not there), and unusual excitement, nervousness, or irritability.

This medicine may cause you to do things while you are still asleep that you may not remember the next morning. It is possible you could drive a car, sleepwalk, have sex, make phone calls, or prepare and eat food while you are asleep or not fully awake. Tell your doctor right away if you learn that any of these has happened.

Do not change your dose or stop using it without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping completely. Stopping this medicine suddenly may cause withdrawal side effects.

After taking zaleplon for insomnia, you may have difficulty sleeping (rebound insomnia) for the first few nights after you stop taking it.

If you think you or someone else may have taken an overdose of this medicine, get emergency help at once. Taking an overdose of zaleplon or taking alcohol or other CNS depressants with zaleplon may lead to breathing problems and unconsciousness. Some signs of an overdose include: clumsiness or unsteadiness, confusion, severe drowsiness, low blood pressure, unusual dullness or feeling sluggish, and troubled breathing.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
