After taking a dose of Methylprednisolone it should be out of your system after 28 hours (just over a day).
The half life of Methylprednisolone varies from 1.8 to 5.2 hours. This is the time it takes for the drug levels in your plasma to reduce by half. For a drug to be totally eliminated from your system it takes around 5.5 times the half life.
Other factors to consider 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.
