A member asked:

How long does methotrexate stay in your system?

A doctor has provided 1 answer

Not enough data: Methotrexate has a half life of 15 hours. It should be totally gone from the blood fairly quickly but can remain in the liver longer. We do not have human studies to say how long that it.

Hi, I'm on Plasmaquine and Methotrexate 7.5mg x 1 per week for arthritis. I'm concerned that the Methotrexate may weaken my immune system and make me more vulnerable to Covid-19. Would it not be safer to discontinue use untill the threat has passed?
