In brief: Depends on…
Dose & how long you were on it.
Mtx's half life (amount of time for active med to be reduced by 1/2) is given as 3-15 hours but varies according the dose. It takes at least 4-5 half lives for a drug to be eliminated from the system, assuming there is normal liver & kidney function.
