Artvigil (armodafinil) effectively manages narcolepsy by increasing alertness and decreasing excessive daytime sleepiness. It works by changing neurotransmitters in the brain, particularly dopamine, to help users remain attentive. When compared to modafinil, Artvigil may have a longer duration of effect and is typically used once daily in the morning. While it does not cure narcolepsy, it does greatly improve daytime function for many people. Headache, sleeplessness, nausea, and anxiety are some of the potential side effects. Overall, Artvigil is regarded as a trustworthy alternative for narcolepsy therapy when administered under physician supervision, while its efficacy varies significantly from patient to patient.
