(zal' e plon)
WHY is this medicine prescribed?
Zaleplon is used to treat insomnia (difficulty falling asleep). Zaleplon does not help you to stay asleep longer or decrease the number of times that you awaken during the night. Zaleplon is in a class of medications called hypnotics. It works by slowing activity in the brain to allow sleep.
HOW should this medicine be used?
Zaleplon comes as a capsule to take by mouth. It is usually taken as needed at bedtime or after trying unsuccessfully to fall asleep. Do not take zaleplon with or shortly after a heavy, high-fat meal. Zaleplon may not work well if it is taken with high fat foods. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take zaleplon exactly as directed.
You will probably become very sleepy soon after you take zaleplon and will remain sleepy for some time after you take the medication. Plan to go to bed right after you take zaleplon and to stay in bed for 7 to 8 hours. Do not take zaleplon if you will be unable to go to bed right away and remain asleep for 7 to 8 hours after taking the medication. If you continue to walk around after taking zaleplon, you may experience dizziness, lightheadedness, problems with memory and coordination, or hallucinations (seeing things or hearing voices that do not exist). If you get up too soon after taking zaleplon, you may experience memory problems.
You should be sleeping well within 7 to 10 days after you start taking zaleplon. Call you doctor if your sleep problems do not improve during this time, if they get worse at any time during your treatment, or if you notice any changes in your thoughts or behavior.
Zaleplon can be habit-forming. Do not take a larger dose, take it more often, or take it for a longer time than prescribed by your doctor.
Do not stop taking zaleplon without talking to your doctor. If you suddenly stop taking zaleplon, you may experience withdrawal symptoms such as unpleasant feelings, stomach and muscle cramps, vomiting, sweating, shakiness, and rarely, seizures. Your doctor will probably decrease your dose gradually.
You may have more difficulty falling asleep or staying asleep on the first few nights after you stop taking zaleplon than you did before you started taking the medication. This is normal and usually gets better without treatment after one or two nights.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with zaleplon and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website ( Web Site) or the manufacturer's website to obtain the Medication Guide.
