Here is My Question:
How long does Plegridy remain in your system once you stop?
Plegridy’s half life is ~78 hours (meaning it takes 78 hours for the body to remove 50% of the Plegridy in your system). It is primarily removed by the kidneys, so if there is kidney disease, it may take longer. Given the half life of the drug, it is reasonable to assume it would take approximately 2 weeks to be removed from the body.
