What is the most important information I should know about modafinil?

Use caution when driving, operating machinery, or performing other hazardous activities. Modafinil may affect your judgment, thinking, or motor skills. If you experience any of these effects, avoid hazardous activities.
It is best to avoid alcohol while taking modafinil. Alcohol or modafinil may have altered effects if taken together.
Modafinil may decrease the effects of hormonal methods of birth control including birth control pills and depot and implantable formulations (e.g., Norplant, Depo-Provera). Use a second, nonhormonal form of birth control while taking modafinil, and for one month after stopping modafinil, if prevention of pregnancy is desired.
Modafinil may be habit forming. You should discuss the abuse and dependence potential of modafinil with your doctor. Do not stop taking modafinil without first talking to your doctor. Your doctor may want to gradually lower the dose of the medication before stopping treatment.

What is modafinil?
The exact way that modafinil works is not known.
Modafinil is used to improve wakefulness in patients with excessive daytime sleepiness associated with narcolepsy, obstructive sleep apnea/hypoapnea syndrome (OSAHS), and shift work sleep disorder (SWSD).
Modafinil may also be used for purposes other than those listed in this medication guide.

What should I discuss with my healthcare provider before taking modafinil?
Before taking modafinil, tell your doctor if you have
  • left ventricular hypertrophy (enlarged left heart ventricle);
  • chest pain, irregular heartbeats, or other symptoms of mitral valve prolapse due to central nervous system stimulant use;
  • a recent history of a heart attack;
  • high blood pressure;
  • angina (chest pain);
  • abused medicines called stimulants or street drugs;
  • a history of mental illness;
  • kidney disease; or
  • liver disease.
You may not be able to take modafinil, or you may require a dosage adjustment or special monitoring during treatment if you have any of the conditions listed above.
Modafinil is in the FDA pregnancy category C. This means that it is not known whether it will be harmful to an unborn baby. Do not take modafinil without first talking to your doctor if you are pregnant or could become pregnant during treatment.
It is not known whether modafinil passes into breast milk. Do not take modafinil without first talking to your doctor if you are breast-feeding.
If you are older than 65 years of age, you may be more likely to experience side effects from modafinil. You may require a lower dose or special monitoring during treatment.

How should I take modafinil?

Take modafinil exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.
Take each dose with a full glass of water.
Modafinil can be taken with or without food.
Modafinil is usually taken once a day. Follow your doctor's instructions.
It is important to take modafinil regularly to get the most benefit.
Modafinil is not a replacement for sleep. Modafinil may reduce the signs of sleepiness, but may not completely treat this problem. Some drowsiness may continue. Potentially hazardous activities such as driving or operating machinery should only be performed if the level of wakefulness achieved is sufficient to permit such activities.
Other treatments such as CPAP (continuous positive airway pressure) use should be continued as directed by your doctor if you have obstructive sleep apnea/hypoapnea syndrome (OSAHS) and are taking modafinil.
Modafinil may be habit forming. You should discuss the abuse and dependence potential of modafinil with your doctor. Do not stop taking modafinil without first talking to your doctor. Your doctor may want to gradually lower the dose of the medication before stopping treatment.
Store modafinil at room temperature away from moisture and heat.

What happens if I miss a dose?
Take the missed dose as soon as you remember as directed by your doctor. A missed dose taken late in the waking day may cause insomnia. If you don't remember until it is almost time for the next dose, skip the missed dose and take only the next regularly scheduled dose. Do not take a double dose of this medication unless otherwise directed by your doctor.

What happens if I overdose?
Seek emergency medical attention if an overdose is suspected.
Symptoms of a modafinil overdose may include excitation, agitation, insomnia, sleep disturbances, anxiety, irritability, aggressiveness, confusion, nervousness, tremor, palpitations, nausea, and diarrhea.

What should I avoid while taking modafinil?

It is best to avoid alcohol while taking modafinil. Alcohol or modafinil may have altered effects if taken together.
