I have been told to avoid the sun while taking methotrexate. Why?

This and quite a few medications make your skin more sensitive to the sun, causing you to burn easily.

Kaismama is right. If you can't avoid the sun make sure you wear sunscreen and re-apply it frequently. Cover up as much as possible.

Cocoabean,
Not only does it make your skin more sensative to the sun as the others pointed out, it can also make you more easliy succeptible to bruising as well as cause you to have headaches. Hope this helps.
