How long does it take glipizide to leave the system?

Glipizide has a half-life of about 2 to 4 hours in healthy individuals, meaning it takes that long for half of the drug to be eliminated from the body. Generally, it takes about 5 half-lives for a drug to be considered cleared from the system, so glipizide would typically be eliminated within 10 to 20 hours after the last dose. However, individual factors such as kidney function and dosage may affect this timeframe.
