Opdivo stays in your system for a very long time, up to 3 to 4 months (100 to 125 days). This is based on the half-life of Opdivo, which is 25 days. The half-life is the time it takes for half of a drug to be removed from the body, and experts have agreed it takes 4 to 5 half-lives for a drug to be completely removed from the body. This calculates out to 100 to 125 days for Opdivo. This means that side effects can still occur because of Opdivo a few months after you stop taking the drug.
