How long does prednisone stay in your system?
Medically reviewed by Drugs.com. Last updated on Nov 4, 2024.
You could expect a dose of prednisone to stay in your system for 16.5 to 22 hours.
The elimination half life of prednisone is around 3 to 4 hours. This is the time it takes for your body to reduce the plasma levels by half. It usually takes around 5.5 half lives for a drug to be completely eliminated from your system.
Other factors that can cause variation to the elimination time include:
- How much and how often you have taken the drug.
- Your metabolic rate – a slower metabolism will increase the time a drug remains in your system.
- Your age and health – older age and poor health will generally increase the time the drug stays in your system.
- Body mass – generally the bigger you are the longer a drug will remain in your system.
