Let's take a minute to talk about your medication.

This is modafinil, also known as Provigil. This medicine can help you to stay awake. It helps to treat sleepiness that can be caused by shift work, sleep apnea, or narcolepsy. It may have other uses, too. 

It is often taken one time each day. You should take it exactly as your doctor tells you to. Your doctor will determine what dose is right for you and what time of day you should take your dose. Call your doctor if your dose does not control your condition. You should not change your dose unless your doctor says it's okay.

Most people tolerate this medicine well. Common side effects include nausea, diarrhea, and an upset stomach. It can also cause a headache, back pain, or stuffy nose.  Some people will also feel nervous and anxious, have trouble sleeping, or dizziness. You should wait until you know how this medicine affects you before you do activities that require you to be alert, like driving.  If these or other effects become reasons you want to stop taking it, please talk to your doctor or pharmacist. 

As with any medicine, rare but more serious side effects could occur. With modafinil, this can include serious skin or allergic reaction. You should read the Medication Guide to know what to watch for and when to report changes. 

Modafinil can interact with other medicines. You should always check with your doctor or pharmacist before taking other medicines. Also, do not drink alcohol. 

Women should talk to their doctors before becoming pregnant and before breastfeeding.
