While it can be highly effective in managing excessive daytime sleepiness, like all medications, Provigil can cause side effects. It is crucial for patients to be aware of these potential effects, both common and serious, and to know how to manage them effectively. This guide aims to provide comprehensive information for Indian readers on Provigil side effects, their management, and when to seek medical attention. What is Provigil and How Does it Work?
