Modafinil is sold under several brand names, with Provigil being the most well-known. Other brand names for modafinil include Alertec, Modalert, and Vigilance [1][2].
What other forms of modafinil are available?
Beyond branded versions, generic modafinil is also available, often at a lower cost [1].
When does the patent for Provigil expire?
The primary patents for Provigil, originally developed by Cephalon, have expired, allowing for the introduction of generic versions [3]. While initial patents expired around 2006, further patent litigation and extensions, particularly concerning formulations and methods of use, have influenced the market entry of generics over time [3].
Who makes generic modafinil?
Several pharmaceutical companies manufacture generic modafinil. Companies like Teva Pharmaceuticals, Mylan, and Sun Pharmaceutical Industries are among those that have produced generic versions [1].
What are the uses for modafinil?
Modafinil is a medication prescribed to improve wakefulness in adults who experience excessive sleepiness due to diagnosed sleep disorders such as narcolepsy, obstructive sleep apnea (OSA), or shift work sleep disorder (SWSD) [4][5]. It is not intended for use by individuals with mild or occasional daytime sleepiness [4].
Can modafinil be used off-label?
While primarily prescribed for specific sleep disorders, modafinil is sometimes used off-label for conditions like attention deficit hyperactivity disorder (ADHD) and to combat fatigue associated with other medical conditions or treatments [4]. It is also sometimes used by individuals without a prescription to enhance cognitive functions like focus and alertness, though this use is not FDA-approved [4].
What are the potential side effects of modafinil?
Common side effects of modafinil can include headache, nausea, nervousness, anxiety, insomnia, and dizziness [5]. Less common but more serious side effects can include severe skin reactions, such as Stevens-Johnson syndrome, and psychiatric symptoms like hallucinations or manic behavior [5].
How does modafinil work?
The exact mechanism by which modafinil promotes wakefulness is not fully understood. However, it is believed to affect neurotransmitters in the brain, such as dopamine and norepinephrine, to increase alertness [4][5]. It is chemically distinct from traditional stimulant medications like amphetamines [4].
How does modafinil compare to other wakefulness-promoting medications?
Modafinil is often considered a first-line treatment for excessive sleepiness associated with narcolepsy, OSA, and SWSD. Compared to amphetamines, it generally has a lower potential for abuse and a different side effect profile [4]. Other medications for these conditions may include stimulants or specific treatments for underlying causes of sleep apnea.
