How Long Does Lisinopril/ Hydrochlorathiazide Stay In Your System
How long a drug stays in one's system will vary somewhat depending on a person's size, weight, metabolism, etc. A good rule of thumb is that a drug stays in the system for five to six times the half-life of the drug. Lisinopril's half-life is 12 hrs., so it would stay in the system for about 3 days. Hydrochlorathiazide's half-life ranges from 5.6 - 14.8 hrs., so it could be in the system for as little as 28 hours or as much as 88.8 hrs.
