For example, a drug with a half-life of four hours will be half as effective at the four-hour mark, and its effects will continue to slowly decrease after that, becoming largely inactive around eight hours after it was taken. The absorption half-life was approximately 3 to 4 hours and the terminal half-life ranged from 40 to 50 days. The long half-life can be attributed to extensive tissue uptake rather than through decreased excretion. Peak plasma levels of hydroxychloroquine were seen in about 3 to 4 hours.
