Pharmacist tips for Armodafinil (Nuvigil)
- Take armodafinil (Nuvigil) with or without food.
- For obstructive sleep apnea: Keep using your other sleep apnea treatments while taking armodafinil (Nuvigil). For example, if your sleep specialist told you to use a breathing machine like continuous positive airway pressure (CPAP) at night, continue using it. Armodafinil (Nuvigil) can help you feel less sleepy during the day. But it doesn't treat the cause of sleep apnea.
- For shift work disorder (working long or irregular hours): You only need to take armodafinil (Nuvigil) on the days you work. Take it about 1 hour before your shift starts. You don't need to take the medication on days when you aren't working.
- Wait to see how armodafinil (Nuvigil) affects you before doing anything that needs your full attention. This includes driving or using heavy machines. Even with armodafinil (Nuvigil), you might still feel sleepy. The medication might also make it harder to focus, think, or react. If you're worried about this, talk to your prescriber.
- It's best to avoid alcohol while taking armodafinil (Nuvigil). It isn't clear how they interact with each other. But alcohol might worsen side effects like dizziness.
- If you use birth control, talk to your prescriber about the best way to prevent pregnancy during treatment. Armodafinil (Nuvigil) can make hormonal options, like pills, patches, and vaginal rings, work less well. You might need to use an additional barrier method, such as condoms, or switch to a non-hormonal option. Follow this method while taking armodafinil (Nuvigil) and for 1 month after stopping it.
- If you become pregnant while taking armodafinil (Nuvigil), tell your care team right away. There isn't enough information to know if it's safe to take during pregnancy. If you take armodafinil (Nuvigil) while pregnant, you're encouraged to join a pregnancy registry that helps monitor the safety of this medication for you and your baby. To learn more, talk to your care team or call 1-866-404-4106.
- Make sure you still follow good sleep habits while taking armodafinil (Nuvigil). Even though the medication helps you feel more awake during the day, it doesn't replace getting proper rest. Good sleep hygiene is still an important part of treatment.
