how long does methylin, or ritalin 10 mg stay in your system? how long before it wont show up in a drug screen?
Although it depends on how well your liver and kidneys are functioning, the half-life is between two to four hours, meaning it will be out of your system in less than a day. Certain long-acting forms of Ritalin have the same half-life, but stay in your system longer because it takes longer for them to be absorbed into the body.
