What should I watch for?
Tell your doctor or health care professional if your symptoms do not start to get better or if they get worse.
Do not stop taking except on your doctor's advice. You may develop a severe reaction. Your doctor will tell you how much medicine to take.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you. To reduce the risk of dizzy and fainting spells, do not stand or sit up quickly, especially if you are an older patient. Alcohol may increase dizziness and drowsiness. Avoid alcoholic drinks.
If you are taking another medicine that also causes drowsiness, you may have more side effects. Give your health care provider a list of all medicines you use. Your doctor will tell you how much medicine to take. Do not take more medicine than directed. Call emergency for help if you have problems breathing or unusual sleepiness.
After taking this medicine for sleep, you may get up out of bed while not being fully awake and do an activity that you do not know you are doing. The next morning, you may have no memory of the event. Activities such as driving a car ("sleep-driving"), making and eating food, talking on the phone, sexual activity, and sleep-walking have been reported. Call your doctor right away if you find out you have done any of these activities. Do not take this medicine if you drink alcohol or have taken another medicine for sleep, since your risk of doing these sleep-related activities will be increased.
Do not take this medicine unless you are able to stay in bed for a full night (7 to 8 hours) before you must be active again. You may have a decrease in mental alertness the day after use, even if you feel that you are fully awake. Tell your doctor if you will need to perform activities requiring full alertness, such as driving, the next day. Do not stand or sit up quickly after taking this medicine, especially if you are an older patient. This reduces the risk of dizzy or fainting spells.
If you or your family notice any changes in your behavior, such as new or worsening depression, thoughts of harming yourself, anxiety, other unusual or disturbing thoughts, or memory loss, call your doctor right away.
After you stop taking this medicine, you may have trouble falling asleep. This is called rebound insomnia. This problem usually goes away on its own after 1 or 2 nights.
Women should inform their doctor if they wish to become pregnant or think they might be pregnant. There is a potential for serious side effects to an unborn child. Talk to your health care professional or pharmacist for more information.
