Read this Medication Guide before you start taking modafinil tablets and each time you get a refill. There may be new information. This information does not take the place of talking with your doctor about your medical condition or treatment.
What is the most important information I should know about modafinil tablets?
Modafinil tablets may cause serious side effects including a serious rash or a serious allergic reaction that may affect parts of your body such as your liver or blood cells. Any of these may need to be treated in a hospital and may be life-threatening.
Stop taking modafinil tablets and call your doctor right away or get emergency help if you have any of these symptoms:
- skin rash, hives, sores in your mouth, or your skin blisters and peels
- swelling of your face, eyes, lips, tongue, or throat
- trouble swallowing or breathing

What are modafinil tablets?
Modafinil tablets are a prescription medicine used to improve wakefulness in adults who are very sleepy due to one of the following diagnosed sleep disorders:
- narcolepsy
- obstructive sleep apnea (OSA). Modafinil tablets are used to treat excessive sleepiness, but not the obstruction or medical condition that is causing OSA. You should talk with your doctor about treatments for OSA before you start taking modafinil tablets and during treatment with modafinil tablets. Modafinil tablets do not take the place of treatments that your doctor has prescribed for OSA. It is important that you continue to use these treatments as prescribed by your doctor.
- shift work disorder (SWD)
Modafinil tablets will not cure these sleep disorders. Modafinil tablets may help the sleepiness caused by these conditions, but it may not stop all your sleepiness. Modafinil tablets do not take the place of getting enough sleep. Follow your doctor’s advice about good sleep habits and using other treatments.
| Modafinil is a federally controlled substance (C-IV) because it can be abused or lead to dependence. Keep modafinil tablets in a safe place to prevent misuse and abuse. Selling or giving away modafinil tablets may harm others, and is against the law. Tell your doctor if you have ever abused or been dependent on alcohol, prescription medicines or street drugs. |
