Modafinil is used to help people who have narcolepsy, obstructive sleep apnea/hypopnea syndrome (OSAHS), or shift work sleep disorder (SWSD) to stay awake during the day. Modafinil does not cure these conditions and will only work as long as you continue to take it .
modafinil is available only with your doctor's prescription.
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For modafinil, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to modafinil or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of modafinil in children below 16 years of age. Safety and efficacy have not been established .
Although appropriate studies on the relationship of age to the effects of modafinil have not been performed in the geriatric population, geriatrics-specific problems are not expected to limit the usefulness of modafinil in the elderly. However, elderly patients may have a slower removal of modafinil from the body, which may require an adjustment of dosage in patients receiving modafinil .

modafinil does not take the place of getting enough sleep. It should not be used for occasional sleepiness that has not been diagnosed as narcolepsy, sleep apnea, or shift work sleep problems. Ask your doctor for advice about good sleep habits .
If you have sleep apnea and use a continuous positive airway pressure (CPAP) machine at night, continue using this machine with the medicine .
