Median half life 32d: The median half life of Rituxan (rituximab) is 32 days. It takes approximately 5 half-lives before a drug is considered "gone" from the system.

Remember measurement of drug in the system is not the same as the side-effect of the drug or the length of time the lymphocyte population is affected. ...Read more
