It takes approximately 16.5 to 22 hours for Prednisone to be out of your system.
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 x half-life for a drug to be completely eliminated from your system.
This is (5.5 x 3) 16.5 hours to (5.5 x 4) 22 hours for Prednisone.
Other factors also need to be taken into account and include:
1. How much and how often you have taken the drug.
2. Your metabolic rate – a slower metabolism will increase the time a drug remains in your system.
3. Your age and health – older age and poor health will generally increase the time the drug stays in your system.
4. Body mass – generally the bigger you are the longer a drug will remain in your system.
