How it works

From the US prescribing label for the same active substance (Azathioprine). It describes the substance, not this exact product.

Azathioprine is well absorbed following oral administration.

Maximum serum radioactivity occurs at 1 to 2 hours after oral 35 S-azathioprine and decays with a half-life of 5 hours.

Half-life5 h
Mostly cleared after≈ 25 hfive half-lives — our arithmetic
How the body breaks it down

Azathioprine is metabolized to 6-mercaptopurine (6-MP).

How it leaves the body

Both compounds are rapidly eliminated from blood and are oxidized or methylated in erythrocytes and liver; no azathioprine or mercaptopurine is detectable in urine after 8 hours.
